Travis, Thank you!!! I have an 85 Trac that has been sitting for a decade. I watched your video and learned a great deal! I WD-40'd cables & moving parts, and shot a few squirts into the spark plug hole. I then sprayed lithium grease on the chains. I turned the engine over by hand as you had done, then used sand paper on the points. After that I air sprayed and sprayed electric connection cleaner on the points and wire connections. Then I cleaned the carb, and sanded the spark plug. It fired up on the 5th kick! I let it run then adjusted the idle. The best news is I am doing 32mph (I weigh 240)!! So again, thank you very much for this video!!
Just got my first project 'ped. Even though it's not a Puch this video has been a huge help in knowing what I should check. I know UA-cam comments can be a disaster (though it doesn't look too bad here, guess moped'ers are good peeps) so I wanted to leave a nice comment and tell you how much I appreciate you making this vid!
Thank you, I learned a whole lot watching you go through the steps that I'm taking now with my Tomos A3. First two-stroke, first bike with points. I'm an avid motorcyclist and a home wrench but this older Moped is a great new challenge. Thanks for being so concise and clear for us!
I finnally fixed the problem. It was tedious. I exposed the whole wiring system. I checked all wires for puncture marks etc. Cleaned all grounds and disconected the taillights. Had a bad connection which inturn burned out the circuit in the connection box. Cleaned and resaltered. Works fine.I changed the design to ensure that it wouldn't happen agin. Thanks alot. You the man....
I had one bike that the tank was so rusty on the inside that I just took a plastic gas tank off one of my junk riding mowers and made it work. I used an inline fuel filter and shut off valve. It worked great for years.
same my older brother bought one at an action and gave it to me for a suprise and i've never messed with two strokes so i had no idea what to do with it
Thanks a lot travis, used your video to help start and get running my fathers vintage puch that hasn’t run in 30 years, after following the video it ran perfectly.
I've really been enjoying watching your videos. This one especially was done very professionally for an instructional video done alone. You're very knowledgeable, light up, and you edit them very well. Thank you. 👌😜👍🛵🛵
Dude your voice cracks just as much as mine! love it as a deep voiced guy who gets flack for it from time to time. More importantly, I searched a lot after getting a couple very rough Moby's for free and am just getting started. Your videos are concise and easy to follow. Thanks for making good stuff!
After watching several of your videos I can proudly say that my 1978 puch maxi is running like a top my kids love it thanks guys. And I would like to mention that it was free because he could not figure out how to make it run!!!!!
I was hoping you'd point out Evaporust! It's the best. I've used it on several bikes. I also really liked your method of removing the kickstand spring! Nice work.
Thanks for responding. Looks like I may have do some serious rewiring to do. My bulbs are good. My swithes are cleand and good. Icleaned all ground connections. Checked for pinch points. Everything.... still no luck. Thanks agin. Ill be back at it tomorrow.
Ah bummer, it's nice when the fix is easy. The switches are funny...the test for them is to tape the two connectors going into them together and see if it still dies when you hit the brake lever. Obviously the bike can't be ridden like this for safety reasons/no brake light - but even if the switch contacts are good and clean it could still be bad. Beyond scuffing up the grounds with sandpaper I would also look for a simplified Tomos A3 wiring guide on MopedArmy for when you do go to re-wire, less wiring makes troubleshooting e-z!
Supertech oil works just fine. Been running it in my F150 for years and it's pushing 300k miles. Project Farm has done loads of oil and other tests on various brands.
Omg!! I had one of those exact models..my aunt gave it to me my last trip to Maine when I was 15 and hauled it back to Kansas... man the thing was a blast!!!
I got my 1970 moped from an old chicken house from my fathers land and we replaced the engine but when we first looked inside the gas can there wasn’t any liquid at all inside and I was amazed that it didn’t rust through at all
Definitely going to have to use these methods to get my newly acquired mopeds running 😎 CL ad, picked up a ‘75 & ‘85 motobecane roadrunner, and scored an old angel ‘moped II’ for free more or less. Paid $150 for the set of (3) of them :p
Years ago I had a flathead V8 in a 53 Ford most cylinders had around 90 a couple had 50 and one or two had 25 lbs per square inch and it was still run a hundred. It was bad valve seats that I could not grind out without doing a complete valve job and on a flat head there is no valve adjustment you have to grind off of the stem or lap it down into the seat
Can you use naval jelly to remove tank rust,and some never dull to clean and polish away surface rust,bikes that sit a long time,you can use stable gas treatment ,so the gas won't turn to varnish.
travis thank you for this video .my story is i found a 1982 honda express out by the curb . it's old and rusty playing a round with it . im new to mophed and how to get them running .
HI! I purchased an old TOMOS STREET MATE last week (yes, from Craigslist) so I can teach myself how to ride before jumping on my other bikes (Yamaha xs400 maxim n Honda Shadow VT700). (I promised my family I'd practice on something "little"). Before I purchased it, I saw the ex-owner ride the heck out of it, kicked it back and off he went, so I loaded it in the back of my sedan and off "I" went! I don't know crap about bikes and I'd like to get it street ready (registered, insured, etc.) by fixing it myself. This little moped has been "suped up" to a 70cc with a different engine, a fancy muffler and ... it has no odometer (?) It has no KEY. I didn't notice that before I got home (oopsie) It's been jury rigged like crazy, but it works like a charm. It has a new battery, the tires are ok, but it has a mess of wires sticking out of the oddest places all jumbled together and placed together with plastic ties. So, where do I start? I'd like to do the work myself given I paid two cents for it. I don't want to start throwing money into it. I'm pretty good with electricity, mechanics and I'm not afraid to get dirty. I cannot tell what year it is cuz the VIN is covered right now by a junk load of jury-rigged wires. I can send you pictures, etc. My question is ... where do I start, what do you suggest and thank you, thank you, thank you for any advice. JG
+Janet Grace-Alvarado It sounds like you're off to a pretty good start. That Tomos will have an A55 engine, year will be 2005+. My understanding is the wiring for A55 motors was borrowed from some Chinese scooter and has a lot of extra wires from the factory. If someone has messed with it even further, but everything works (lights, turn signals, horn, etc) I would recommend leaving it. Myrons has a great guide to modern Tomos electrical linked below: www.myronsmopeds.com/category/service/new-tomos-electrical/ The trouble with buying modified mopeds is that most people don't take the time to property tune after installing a 70 kit. If the previous owner didn't reject the carb there is a danger of it seizing from getting too hot. If you only bought it to get comfortable on two wheels, then it's whatever, but if you plan on riding it as a real form of transportation it'd be worth it to read up on performance tuning since modifying a moped from stock has a lot of different variables (torque specs, carb jetting, exhausts, gearing, clutches). At the very least, I'd exercise caution if the stock oil injection system has been left in place, as a 70 kit will keep the RPMs much higher than the stock pump is used to. www.mopedarmy.com/wiki/Category:For_Newbies www.mopedarmy.com/wiki/Category:Performance_Tuning
Thanks SO MUCH, Travis, for your response and links. I am absolutely not going to be riding this as a mode of transportation. It's solely for practicing and getting my footing on something I can handle until I'm completely comfortable. (ride like a pro dot com) I'd rather practice techniques than "go for a spin". I am very thankful for your response and expertise. THANK YOU!!! Brightest Wishes. JG :D
Ok so Travis I could hug you. Im on my very first project and I needed this video. I bought two mopeds for $450. A Moto Guzzi Robin and a Pacer Super sport. I could only keep one so I sold the Moto Guzzi that was running by the way but it didn't have that awesome top tank. Now Im taking that money and plunking it in to the pacer that wasn't running, good or bad. I didn't watch this video (kicking myself) before I started to tear in to the Pacer. I was very meticulous about bagging and labeling all the screws and so forth so getting this back together will be pretty easy. I have several issues. First when I took the head off I noticed that the cylinder had a lot of burnt crud all over it. (I will check for scoring thanks to your video) Is that something I can clean? or do I replace the cylinder? Next question. Do you know anything about the Morini M01 engine? If so how do you check the points? I cant seem to see them through the fly wheel.
I would say you made the right choice! The M01 is a better motor than the G2 motor on the Moto Guzzi to start out with. As far as the cylinder, carbon buildup is pretty normal because all two strokes are just dirty, plus the oil they had back in the day was pretty crude, so long it wasn't seized it is probably fine. I had an M01 on a Bianchi moped a few years ago, fairly robust little motor. Italian mopeds always have little bitty flywheel windows, you'll have to really fiddle with it, but you should be able to check/adjust without having to buy a flywheel puller.
This is a very good information. But my scooter is a 2008 Scooter 60 miles on it it's a Chinese scooter. And sometimes it has a habit of hard starts or it sometimes will stall while you're actually writing it. But mainly what is cold I have the hard start problem once it warms up it starts fine
^ Correct that is the best practice. Carb cleaner is not advised because it can contain oil, brake cleaner is better since it won't but both will eat insulation. Annotation made, thanks.
I just got a 1979 malaguti commuter II. It has a pedal start and I’m wonder where the battery is. I didn’t see you go over the electrical in this video.
hey, probably a dumb question but it's haunting my dreams. I have a sachs 504 that I can't figure out how.the clutch cable goes through the decompression valve lever to make it open and close when it's pulled. all the videos and pictures Ive seen just look like the cable passes through it. but if I set it up the way it looks the cable wont affect the valve at all. I'm sure this is simple but I just cant figure it out. awesome videos by the way!
nice video. I have a puch maxi 77' cleaned the carb multiple times (atomizer and jet are clean, banjo etc..) Cleaned spark plug and checked for spark, fuel flow seems to be good, no rust in the tank. Going to clean the points today to see if that helps. Could be a wiring issue?
I've taken on an '89 Puch that has been sitting in the garage for the past several months, can you show how to do some of the smaller, simple mainenance as well? Starting with changing the engine stop switch? Thanks!
Pretty helpful video. However, you left out probably the most important step/ part. Just like starting a car, you need to be able to turn the engine over fast enough to start to check for spark, etc. At least seeing your flywheel turn faster than mine did made me realize the starter clutch was messed up on my moped project.
hi, is there any chance you can do a video about checking and setting the timing on these two stroke moped engines? Mine has a minarelli v1. many thanks very good and informative video
+Scott Morgan Hey glad to hear it! Looks like I missed your other comment, apologies - the clutch is usually not a culprit when there are starting problems, more often a cable with too much slack or occasionally the linkage inside the clutch cover needs adjusted but it sounds like you got it sorted
Wow you got your work cut out for you,I would love to see this one when you are done with it ,I would love to own one these,I like better than scooters,do they make a lot of after market parts for these,to speed them up a little,like after market exhaust and carbs,bigger piston
+Saidia Manyuan (Globetrotter5K) Unfortunately I don't spend much time around newer bikes, but it appears that the battery will be under the right side cover. If you dig around on UA-cam you should be able to find a video on charging scooter or motorcycle batteries, sorry I couldn't be of more help!
Love this page! I've been working on a puch Newport for awhile... The only issue I'm still having is that the acceleration is weak! I cant problem solve this. Any ideas?
Hello,friends.I have any questions. 1.How must show when the compression is good? 2.When I need to change ONLY piston rings?-how show the compression tester? 3.When I need to change piston and piston rings? Sory for my bad English :/
nalisim The easiest way is using a kickstarter, if it has some resistance i'd say it's ok. 2: If the compression is low, you should change the piston-rings. I recommend that you change the piston while you do that, but it's not neccesary. :)
hi, I have a trac moped and im just getting started on it say what kind of money am I looking at you know whats the most you've ever invested in one? Thanks for the vids, im in Columbus Ohio later.
I have a 1978 Suchs Balboa moped. It was a barn find and has not started in 30 plus years. Question concerning the ignition under the handle bar,. Is that to lock the steering or start the engine? I do not have a key.
Travis, I'm fixing up an old Puch Newport; I noticed it only takes leaded gas. Since you can only buy leaded gasoline today, what do you usually use for fuel?
Hey Travis. I bought a 1983 Vespa moped when the pandemic first hit . Just now thinking about getting a look at it and seeing if it will run. Any advise?
Hi there - sure, assuming that is a vespa with pedals, it will have a standard Dellorto SHA carb which came on many different models and is quite easy to clean. Much of the same advice will apply, it will still have ignition points - but it does have a belt and variator instead of a chain, assuming it isn't a single speed Ciao.
Did you know that the e50 motor on the bike on this video have 4 bearings! and not the typical 3 bearings! You can see the difference on the clutch side on the bike. It has 3 bearings if the closing is roundm if the closing has 2 vertical stripes i has 4 bearings as the bike in this video!
I was given a 1980 Sachs Prima moped by my uncle. It has around 2000 miles on it and appears to be in good condition but when I brought it home it would not start. I took it to a local mechanic who had it running/idling well at his shop. He had cleaned the carberator, put fresh mixed fuel in it. I brought it home and took it about a half mile down the street and it quit and I cannot get it running. The mechanic suggested that it may be the crank seals. Any ideas about what I should try?
you think maybe you can't get over 90psi on that one puch could be because it's tapping the Schrader valve, being a high comp head and all.. I noticed you have a vespa si, I have a ciao with problems, cylinder is free but there's a rough patch during rotation, do you know what this could be and why it's keeping my motor from running?
_Bach Europe dudes only! It is a popular conversion here in the US, we got pretty much only pedal e50s until the 1990s when some Korados came with a kickstart.
TravisTutorial okay that is interesting. Almost all the mopes with gears have kickstart. But we puch maxi's with pedals and other one geared mopeds too.
Just got a 1978 Puch Magnum XK, it was a barn find. I have spark, compression and going to clean the tank. I have the carb apart now and you mentioned the part that holds the float should have a rubber tip, mine does not. Also how did you get the bronze center piece out that the throttle cable goes down into and is I between the floater? Thank you and if you have any more exhaust laying around for sale I may be interested!!
Hey-ya! Old comment, but the float needle will need a rubber tip or you'll have leak city. Treatland.tv for the replacement. The atomizer can be removed with a deep 5mm socket.
We cleaned the carburetor and we have gas flow when we take it out but when we put it back in the flow stops i don’t know if it’s the carburetor itself because it looks clean or if it’s somewhere else
Do you have a video on fixing misfires? I have a newly acquired FreeStyle and 2hp single speed, I find I hear popping at times when the engine is running full speed or when I let off throttle. It does not seem to be very consistent. The unit runs well, thought there is a lot of crud in the tailpipe. All original, accept the float I put in the carb.
hello, cool video man i have a tomos a35 moped and it runs well but for some reason it dies when i put the choke on what would you suggest to fix this.
My first guess would be air leaks, I'd do the carb cleaner check by spraying the mating surfaces (most possible culprits are the carb -> intake junction, spark plug, cylinder -> head, and head -> base) to see if you have RPM changes or if it kills the bike. If it passes that, I'd verify the carb is clean, on the Dellorto SHA that is most likely on that you are really just looking at the main jet inside the bowl.
Some years ago I bought a Suzuki FZ50. After a few weeks one day the exhaustion pipe fell off while riding the moped and the pipe broke. I bought a new one. But after that the moped didnt have much torque when going even slightly up hill. Apart from that it was ok. Havent used the moped for nearly ten years. It has been dripping black oil since then from the back of the exhaust pipe. and the oil tank has also got empty. Would you say this is worth touching?
Hey great videos! I have a puch maxi and I don't know if its getting gas.. when petcock is in the on position nothing drips out ? Does it need replaced? Or is it vacuum operated?
100% Gravity - Petcock could definitely be clogged, you could take it apart since they're pretty simple, or you could replace, the "puch maxi gold petcock" on Treatland.tv is a fine replacement. If you take the petcock off and gas comes pouring out make sure it's clear and free of debris.
I have a 75 garelli eureka but my compression isnt blowing any air out of the spark plug hole when i did the finger test what could my problem be? And also what do i put in the oil tank? What kind of oil do i use. I have a new spark plug that sparks up, i have fuel just no compression
I have a 49cc scooter. Was running great. Park it and the next day it wouldn't start. When you try to start it ,it turns. But when you open the throttle the motor tries to stop. Just like if ur battery was low. If you let go of the throttle it will turn over at normal speed. But wont turn on. I replace the spark plug. Checked for spark. Cleaned out the carb and adjusted the valves. What can this be?
uhm i dont know the word i. english but you have the gold metal thing inside the carb with a little hole in it it should say a number 50-100 between in your case i would try getting a lower size
Travis, Thank you!!! I have an 85 Trac that has been sitting for a decade. I watched your video and learned a great deal! I WD-40'd cables & moving parts, and shot a few squirts into the spark plug hole. I then sprayed lithium grease on the chains. I turned the engine over by hand as you had done, then used sand paper on the points. After that I air sprayed and sprayed electric connection cleaner on the points and wire connections. Then I cleaned the carb, and sanded the spark plug. It fired up on the 5th kick! I let it run then adjusted the idle. The best news is I am doing 32mph (I weigh 240)!!

Hell yeah! Happy wrenching, the A3 is a great engine but the stock encarwi carb is a little goofy
The Dellorto is stock on this one ('91). That much is in great shape at least!
Crazy how precise you make things, and how far ahead you planned it! Absolute amazing project
Thank you! Cheers!
I finnally fixed the problem. It was tedious. I exposed the whole wiring system. I checked all wires for puncture marks etc. Cleaned all grounds and disconected the taillights.

Oh man, glad you sorted it out! Always great to hear how repairs turned out, ride on!
I had one bike that the tank was so rusty on the inside that I just took a plastic gas tank off one of my junk riding mowers and made it work. I used an inline fuel filter and shut off valve. It worked great for years.

Did you get your moped running?
Cheers
Did it run for several months and randomly stopped working again. I have to take it back apart and figure why it won't start up again
Thanks a lot travis, used your video to help start and get running my fathers vintage puch that hasn’t run in 30 years, after following the video it ran perfectly.
I'm so glad to hear it!
youre video on Bing carb rebuild was very thorough and close up and slow and I did exactly what you did. It was great. thank you!
I've really been enjoying watching your videos. This one especially was done very professionally for an instructional video done alone. You're very knowledgeable, light up, and you edit them very well. Thank you. 👌😜👍🛵🛵
You're welcome! I have fun throughout the whole process
Thanks dude, just what I needed, plain and simple info on how to fix and maintain a moped. Subbed!
Dude your voice cracks just as much as mine! love it as a deep voiced guy who gets flack for it from time to time. More importantly, I searched a lot after getting a couple very rough Moby's for free and am just getting started. Your videos are concise and easy to follow. Thanks for making good stuff!
Glad they are helpful!
i didnt even notice voice cracks haha, so used to hearing my own crack.
After watching several of your videos I can proudly say that my 1978 puch maxi is running like a top my kids love it thanks guys. And I would like to mention that it was free because he could not figure out how to make it run!!!!!
Haha yes! That is the spirit of mopeds, great to hear!!
I was hoping you'd point out Evaporust! It's the best. I've used it on several bikes. I also really liked your method of removing the kickstand spring! Nice work.
@Rob De vogel that's what I was saying.

omg THANKYOU! picked up a 2009 ssr lazer 5 for 150$ w a rusted gas tank and your vinegar and alcohol tip was essential.
Bought a 2005 Tomos Targa LX project bike & had no idea how to restore it until now 🙏🏼 thank q
This soo reminds me to my days as a teenager....being an apprentice in Puch and Zuendapp shop.....You do a very proper job here...way to go...
Thank you! That must have been an amazing experience!
Supertech oil works just fine. Been running it in my F150 for years and it's pushing 300k miles. Project Farm has done loads of oil and other tests on various brands.

I got my 1970 moped from an old chicken house from my fathers land and we replaced the engine but when we first looked inside the gas can there wasn’t any liquid at all inside and I was amazed that it didn’t rust through at all
Just got my first moped for free because it didn't run! Watching all your videos. I just got the unsiezed now on to spark!
Wooooo!
jesus ! you just have a Puch Sport with a E50 engine standing in your shed !😅 In Switzerland these things cost an absolutd fortune (+-3000Dollars)
I love dell'Orto carburetors... In Italy the most of the old mopeds have this brand of carburetor
Yes it is better..! The old model 19..Del orto..with ( guillotine)...was really better...but MIKUNI..Also
Definitely going to have to use these methods to get my newly acquired mopeds running 😎
CL ad, picked up a ‘75 & ‘85 motobecane roadrunner, and scored an old angel ‘moped II’ for free more or less. Paid $150 for the set of (3) of them :p
Years ago I had a flathead V8 in a 53 Ford most cylinders had around 90 a couple had 50 and one or two had 25 lbs per square inch and it was still run a hundred.

travis thank you for this video .my story is i found a 1982 honda express out by the curb . it's old and rusty playing a round with it . im new to mophed and how to get them running .
NGK SPARK PLUGS SAVE THE DAY.
Blows your finger off!?! Lol! Man your hard core!
I look forward to the first start video i just picked up a 77 maxi sport and got it running the carb was clogged
Great video travis ,
great info ,keep up the great work

It sounds like you're off to a pretty good start. That Tomos will have an A55 engine, year will be 2005+.
My understanding is the wiring for A55 motors was borrowed from some Chinese scooter and has a lot of extra wires from the factory.

The trouble with buying modified mopeds is that most people don't take the time to property tune after installing a 70 kit. If the previous owner didn't reject the carb there is a danger of it seizing from getting too hot. If you only bought it to get comfortable on two wheels, then it's whatever, but if you plan on riding it as a real form of transportation it'd be worth it to read up on performance tuning since modifying a moped from stock has a lot of different variables (torque specs, carb jetting, exhausts, gearing, clutches). At the very least, I'd exercise caution if the stock oil injection system has been left in place, as a 70 kit will keep the RPMs much higher than the stock pump is used to.

As far as the cylinder, carbon buildup is pretty normal because all two strokes are just dirty, plus the oil they had back in the day was pretty crude, so long it wasn't seized it is probably fine. I had an M01 on a Bianchi moped a few years ago, fairly robust little motor. Italian mopeds always have little bitty flywheel windows, you'll have to really fiddle with it, but you should be able to check/adjust without having to buy a flywheel puller.
Voice cracks are funny 😂
Your last name is funny
Crack voices in my head are funny too.
Lol
This is a very good information. But my scooter is a 2008 Scooter 60 miles on it it's a Chinese scooter. And sometimes it has a habit of hard starts or it sometimes will stall while you're actually writing it. But mainly what is cold I have the hard start problem once it warms up it starts fine
I may give these a try, i have an old 77 tomos i wanna try to get running again.
I would love too see a puegoet bike next. Thise things Are sick. I also love puch, but i have a puegot
....Thanks for posting this...It was very helpful....
you dont want to use carb or brake cleaner on ignition, use contact cleaner, those others can melt the insulation on your coils
^ Correct that is the best practice. Carb cleaner is not advised because it can contain oil, brake cleaner is better since it won't but both will eat insulation. Annotation made, thanks.
I just got a 1979 malaguti commuter II. It has a pedal start and I’m wonder where the battery is. I didn’t see you go over the electrical in this video.
hey, probably a dumb question but it's haunting my dreams. I have a sachs 504 that I can't figure out how.the clutch cable goes through the decompression valve lever to make it open and close when it's pulled. all the videos and pictures Ive seen just look like the cable passes through it. but if I set it up the way it looks the cable wont affect the valve at all. I'm sure this is simple but I just cant figure it out. awesome videos by the way!
nice video. I have a puch maxi 77'
cleaned the carb multiple times (atomizer and jet are clean, banjo etc..)
Cleaned spark plug and checked for spark, fuel flow seems to be good, no rust in the tank. Going to clean the points today to see if that helps.
Could be a wiring issue?
Excellent tutorial - glad I subscribed!
I've taken on an '89 Puch that has been sitting in the garage for the past several months, can you show how to do some of the smaller, simple mainenance as well? Starting with changing the engine stop switch? Thanks!
Need a video on how to overhaul the wheel hubs of a moped there is zero videos on YT how how to do that.
Thanks!
Get a Honda express please!!
Can you make a video about the things you do to get a bike save?
Like what you always check and do.
just watched your video for the first time ,excellent.
Pretty helpful video. However, you left out probably the most important step/ part. Just like starting a car, you need to be able to turn the engine over fast enough to start to check for spark, etc. At least seeing your flywheel turn faster than mine did made me realize the starter clutch was messed up on my moped project.
hi, is there any chance you can do a video about checking and setting the timing on these two stroke moped engines? Mine has a minarelli v1. many thanks very good and informative video
It's alive. Thanks travis
+Scott Morgan Hey glad to hear it! Looks like I missed your other comment, apologies - the clutch is usually not a culprit when there are starting problems, more often a cable with too much slack or occasionally the linkage inside the clutch cover needs adjusted but it sounds like you got it sorted
Wow you got your work cut out for you,I would love to see this one when you are done with it ,I would love to own one these,I like better than scooters,do they make a lot of after market parts for these,to speed them up a little,like after market exhaust and carbs,bigger piston
Can you make a video on how to charge the battery of a laser 5 SSR moped ?
+Saidia Manyuan (Globetrotter5K) Unfortunately I don't spend much time around newer bikes, but it appears that the battery will be under the right side cover. If you dig around on UA-cam you should be able to find a video on charging scooter or motorcycle batteries, sorry I couldn't be of more help!
TravisTutorial OK; thanks.
Love this page! I've been working on a puch Newport for awhile... The only issue I'm still having is that the acceleration is weak! I cant problem solve this. Any ideas?
why do you use such a long hose on the compression tester? can't you just make a short bit? :) love your vids!
You know the puch maxi air filter boxes split in two too.
Love this video, very helpful information
Can you please make a video about how to wire lights on your puch?
Hello,friends.I have any questions.
1.How must show when the compression is good?
2.When I need to change ONLY piston rings?-how show the compression tester?
3.When I need to change piston and piston rings?
Sory for my bad English :/
nalisim The easiest way is using a kickstarter, if it has some resistance i'd say it's ok. 2: If the compression is low, you should change the piston-rings. I recommend that you change the piston while you do that, but it's not neccesary. :)
you sound almost 100% exactly like Cody from Cody's lab except your voice is a little more soft compared to his more presentation orientated voice
and he has a lot of voice cracks
What are you a voice expert for the fbi
so , I have an old townmate 90cc bike whuch isnt bren ridden in 17 years I hope this would help me turn it back to life .
I thought you had to put a little oil in the plug hole, for a compression test
hi, I have a trac moped and im just getting started on it say what kind of money am I looking at you know whats the most you've ever invested in one? Thanks for the vids, im in Columbus Ohio later.
I have a 1978 Suchs Balboa moped. It was a barn find and has not started in 30 plus years. Question concerning the ignition under the handle bar,. Is that to lock the steering or start the engine? I do not have a key.
Travis, I'm fixing up an old Puch Newport; I noticed it only takes leaded gas. Since you can only buy leaded gasoline today, what do you usually use for fuel?
Hey Travis. I bought a 1983 Vespa moped when the pandemic first hit . Just now thinking about getting a look at it and seeing if it will run. Any advise?
Hi there - sure, assuming that is a vespa with pedals, it will have a standard Dellorto SHA carb which came on many different models and is quite easy to clean. Much of the same advice will apply, it will still have ignition points - but it does have a belt and variator instead of a chain, assuming it isn't a single speed Ciao.
My thumb was blown off. Now I’m missing a thumb.
I'm working on a 70s solo odyssey moped, looking for parts carb, rings , and reed valve
Prv valve leaking and terminates unsafely on your unstrapped water heater
Did you know that the e50 motor on the bike on this video have 4 bearings! and not the typical 3 bearings! You can see the difference on the clutch side on the bike. It has 3 bearings if the closing is roundm if the closing has 2 vertical stripes i has 4 bearings as the bike in this video!
I was given a 1980 Sachs Prima moped by my uncle. It has around 2000 miles on it and appears to be in good condition but when I brought it home it would not start. I took it to a local mechanic who had it running/idling well at his shop. He had cleaned the carberator, put fresh mixed fuel in it. I brought it home and took it about a half mile down the street and it quit and I cannot get it running. The mechanic suggested that it may be the crank seals. Any ideas about what I should try?
Question what is the right spark plug for bianchi moped? I run for a little miles and then stopped.
Thanks
hi Travis great vid
you think maybe you can't get over 90psi on that one puch could be because it's tapping the Schrader valve, being a high comp head and all..
I noticed you have a vespa si, I have a ciao with problems, cylinder is free but there's a rough patch during rotation, do you know what this could be and why it's keeping my motor from running?
My moped is not kick starting the stator is not spinning when kicked
Do you own a e50 with kickstart? i haven't seen any in your videos... and they are very common in Denmark on the puch maxis
_Bach Europe dudes only! It is a popular conversion here in the US, we got pretty much only pedal e50s until the 1990s when some Korados came with a kickstart.
TravisTutorial okay that is interesting. Almost all the mopes with gears have kickstart. But we puch maxi's with pedals and other one geared mopeds too.
Can you start my moped?I was talking to you wherever you're at
Thanks man! Liked and subscribed! 👊🏻
I had to know all of this when I was 13-14 yrs old if I wanted to ride my Tomos Automatic...
Just got a 1978 Puch Magnum XK, it was a barn find. I have spark, compression and going to clean the tank. I have the carb apart now and you mentioned the part that holds the float should have a rubber tip, mine does not. Also how did you get the bronze center piece out that the throttle cable goes down into and is I between the floater? Thank you and if you have any more exhaust laying around for sale I may be interested!!
Hey-ya! Old comment, but the float needle will need a rubber tip or you'll have leak city. Treatland.tv for the replacement. The atomizer can be removed with a deep 5mm socket.
puch
I have a JCPenney pinto. It only has spark sometimes. Any advice? I already changed the condenser
Update: I crossed the horn wires and it ran amazing!
I know this is 5 years old but do you just take the horn out and cross all same colored wires?
We cleaned the carburetor and we have gas flow when we take it out but when we put it back in the flow stops i don’t know if it’s the carburetor itself because it looks clean or if it’s somewhere else
Pistol not moving when pedaling. Suggestion?
I would love to see a video about removing oil injection systems on mopeds.
hey man, what should I do if the pedal is stuck on the moped and won't move??????? PLZ help
Do you have a video on fixing misfires? I have a newly acquired FreeStyle and 2hp single speed, I find I hear popping at times when the engine is running full speed or when I let off throttle. It does not seem to be very consistent. The unit runs well, thought there is a lot of crud in the tailpipe. All original, accept the float I put in the carb.
Popping is usually ignition timing related
Any tips on getting the ignition out
hello, cool video man i have a tomos a35 moped and it runs well but for some reason it dies when i put the choke on what would you suggest to fix this.
My first guess would be air leaks, I'd do the carb cleaner check by spraying the mating surfaces (most possible culprits are the carb -> intake junction, spark plug, cylinder -> head, and head -> base) to see if you have RPM changes or if it kills the bike. If it passes that, I'd verify the carb is clean, on the Dellorto SHA that is most likely on that you are really just looking at the main jet inside the bowl.
Just got a 1978 JC Penny Pitno. New to this. Do you know where I can buy the engine switch? Thanks
Some years ago I bought a Suzuki FZ50. After a few weeks one day the exhaustion pipe fell off while riding the moped and the pipe broke. I bought a new one. But after that the moped didnt have much torque when going even slightly up hill. Apart from that it was ok. Havent used the moped for nearly ten years. It has been dripping black oil since then from the back of the exhaust pipe. and the oil tank has also got empty.
Would you say this is worth touching?
Hey great videos! I have a puch maxi and I don't know if its getting gas.. when petcock is in the on position nothing drips out ? Does it need replaced? Or is it vacuum operated?
100% Gravity - Petcock could definitely be clogged, you could take it apart since they're pretty simple, or you could replace, the "puch maxi gold petcock" on Treatland.tv is a fine replacement. If you take the petcock off and gas comes pouring out make sure it's clear and free of debris.
Great! I ordered a new petcock I hope that does the trick. I subscribed to your channel btw. Keep up the great work!
I have a 75 garelli eureka but my compression isnt blowing any air out of the spark plug hole when i did the finger test what could my problem be? And also what do i put in the oil tank? What kind of oil do i use. I have a new spark plug that sparks up, i have fuel just no compression
I would love to have two them old moped scooters plz me and my wife would ride them every day!
Any tips on removing the condenser
I have a 49cc scooter. Was running great. Park it and the next day it wouldn't start. When you try to start it ,it turns. But when you open the throttle the motor tries to stop. Just like if ur battery was low. If you let go of the throttle it will turn over at normal speed. But wont turn on. I replace the spark plug. Checked for spark. Cleaned out the carb and adjusted the valves. What can this be?
uhm i dont know the word i. english but you have the gold metal thing inside the carb with a little hole in it it should say a number 50-100 between in your case i would try getting a lower size
