- Here's how you properly break-in a new or rebuilt 2 stroke motorized engine.
Don't break it in by breaking it. JS Buy Bellville washers here: hughesmotorized.com/upgraded-... - Навчання та стиль
To everyone: there are a lot of channels devoted to motorized bikes. Some of the advice you will get is okay, some is just plain bad, and some is dangerous. However, this man here, Mr. Hughes, he knows his shit. Listen to his advice and follow it. He won't steer you wrong . He's my #1 go-to guy, and if you have a question he will answer it. I've learned more about these motors from him than all the other channels combined. Plus, he's entertaining, gets to the point, and he will make you laugh. Thanks for listening. Any questions?
Back when i was a kid, i had a 1978 moped powered by McCulloch. It used a 40 to 1 ratio as well. You are correct telling folks to use that ratio. Thank you.
this fellow talks in terms simple and sensibly easy to understand lingo im new to this it has worked for me aaa grade
What I noticed is during break in especially, things will tend to rattle loose, hell my exhaust rattled completely off and my bike died haha! So keep tightening every single thing on the bike during each hot and cool cycle, then make sure to use a bunch of red or blue loctite on things like engine mount nuts, chain tensioner nuts, exhaust and carb intake bolts, etc. It helps a lot and goes a long way to having an optimal experience with these machines.
My guy. . .just put a few more ugguhs into it. . .
Lol mine did too it got loud i was clueless why
Blue for maintenanc. red for permanent
been there many times
I gotta put at least a layer of old popped tube between the metal to metal contacts to reduce the feel of my teeth rattling
I appreciate you posting this, I just needed confirmation, I just finished another New build for the first time in a long time!
Thanks for this video I watch you all the time for anything I need help with on these little bikes… I agree with 40:1 that’s all I’ve ran since I’ve started building these things
Just got mine built ! Gonna start it this morning !
i have to agree with everything he says. i have almost 1200 miles in my bike. you dont break in a weed eater or blower, you just use them. as somebody thats been in this "hobby" for awhile, proper jetting is essential, no matter what carb you use. i prefer the sha clone carb myself. another tidbit of advice to new riders.... dont worry about upgrades until you understand and tame the beast you just built.
Amen. Preach
Maybe you don’t lol
Thank you for sharing. Two friends and I will be building Mine tomorrow.
Awesome videos can’t wait to install my 100cc in the morning
Well said. Yep don’t add extra oil and just run it easy for one full tank if my break in strategy. Sound effects make the explanation much better. I’m impressed. I need some bellville washers! Sell me some! I need about 100 of them 😂
Right on. 100? Buy them from McMaster Carr
I like your personality. Thanks for the audio and tutorial.
Thank you too!
You are the best channel for this content. I love it
Glad you enjoy it!
This man deserves more views and subscribers
Aww shucks. Thanks
Really enjoyed this I finished building mine yesterday
Great to hear!
good advice brother im to purty to get hurt lol . not to mention i dont heal as fast as i used to . you forgot to warn people to watch out for crazies . you know the crazy people who pull out in front of you cause they think they can beat you . i had a bunch of kids pull out in front of me once and stop . i was going about 30 on a spree . i stopped in time but they thought that was just the funniest thing ever . got to watch out for crazies .
Watch out for the crazies! Good advice
And that’s when I fuck them up with mace and fireworks 💥 I’m not playing with people cause the not playing when the don’t have respect for you they lucky you weren’t the wrong guy tires are getting stabbed too they to bust dealing with mace and fire 🔥 works m 80 in they ass they should of went about their business instead of cutting you off😡
@@thompsonbrian8791 how do you mace a car? 3000 lb car vs 75 lb bike. Who's going to win
Great video bro good information that will help a lot of people nice work bro
Thanks ! I
Hope so
Welcome
Love your Vids!!! The bike looks clean but personally I think it would look 10 times better with a Red engine
I appreciate your video, sir.
1K Likes Bro. Thanks for all the Videos. Keep them up.
Breaking my bike in tomorrow! Pacific coast chopper with a centrifugal clutch, cnc cylinder head/intake and new exhaust. Bought a set of jets to find the sweet spot. Hoping it’ll go well!
Good luck!
Thanks for the help
Hey there buddy I had just saw your video on jetting and breaking in an engine. My problem is I went and got a high compression head and a mz65 clone pipe. It starts right up sounds great idle's great but when I ride it everything is good until I get a little over half throttle then nothing bog's down and falls right on its face. It doesn't stall or anything but just has no top end pick up at all. I know it's most likely my jetting because its still an NT carb with stock jetting. When I get my jet's in the mail . do you have any idea on what jet size will be the best to start at. And I'm running 40:1 ratio. And when I say it falls on its face I mean no power past half throttle. Oh also its a g4 jug if that makes a difference.
I've never heard anybody say use 40:1 fuel ratio but I get the feeling thats good advice. So uou want to jet the carb before you use 40:1?
U did this one dope man I like the sound effects added in the video to example what your referring to when explaining but howuch does the torque wrenches go for are they the same ones you can do lugs with on a car? Cause I'd imagine there's a cheaper smaller one could be used for the 10mm sockets harbor freight is only place I'm gonna buy tools from for now on other places don't return broken tools after using them for the first couple times
Appreciate the advice I thought the reason for the torque wrench was for even amount around the cylinder
@@exampleofaking it is for "recommended" for all bolts. They all have a recommended torque value....if you can find them!
Question, my gas scooter calls for 25:1, i believe that would be the break in period. After I can go 32:1 or 40:1. Now if I switch to 32:1 or 40:1 do I have to manually adjust the carburetor idle and fuel mix screws? If I wanted to do a weeks test for each mix and check the plugs for fouling, and do comparisons on temperatures with different fuel mix, isn't it important to adjust the carburetor each time to the correct fuel mix after it warms up??
Just run 40:1 from day one. Then ride
When mentioning that things fall off- a helpful tip to new riders worth mentioning is that threadlocker is your absolute best friend when dealing with chinese hardware and chinese motors. These things rattle something fierce and do not utilize high end grade 8 steel materials like the automotive industry
Hey man my build happens to have a one peice cylinder I’ve been ripping it around for about 3 months I have about 100 miles on it and my clutch locked up the other day and it turns out it was my bucking bar that caused a problem so I replaced it and it ripping again ! These little motors are rip
Awesome, thank you.
You're welcome!
Hey! Thanks for all the videos, it really helped my son and I build one of these beasts! During the first hour, the muffler gasket literally melted and turned to goo. Luckily the exhaust blew it out of the engine. Any idea why this would happen? I read that people use the liquid gasket, would you recommend that? Thanks again, you rock! 🤘🏻
These are better gaskets : amzn.to/3mXJFhx
@@HughesMotorized thanks again!
I over tightened one of my head studs and the acorn nut snapped off with part of the head stud in it, Can you point me in the direction how and where to remove and place it? TYIA
Pull head & cylinder. Remove stud. Be sure and get new gaskets. ua-cam.com/video/G3ww-kkgjPM/v-deo.html
I found some fancy synthetic oil on clearance and used it but I not sure if I was supposed to use more oil than regular oil?
Some run 50 or even 100:1 ratios w/ synthetic
I'm currently running 40:1 but still over heating the rings and locking up the piston, was told more oil would help..any advice?
@@Only-Memories-In-The-End that's exactly what I just did..now running a 75 jet which is way bigger..and now it is one little bad ass ride..
i had tensioner problems got sick of the stupid tensioner bullshit and just shortend the chain havent had a problem since its a good idea if u can shortend ur chain
Im having idling issues as well. But it runs well and it climbs hills too. Just not fast.
Its the zeta 100cc motor.
But for some reason i can only get it to start when going down the hill with the clutch engaged. The moment i let go of the clutch. Thats when the motor starts up. Its annoyi g really.
I just finished my BBR 66/80 build and I’m having difficulty getting the idle set properly. I’ve messed with the cable at the throttle ,on the top of the NT carb, and finally at the idle screw. It is always at a high setting or creeps back up to a high setting after readjusting it. Any recommendations?
post a vid of it running and setting idle and put on my FB page Hughes Motorized and I'll see what I can offer
Hello, there always oil coming out of my exhaust after I turn my engine off and sets for a minute, I run about 36:1 with 95 octane fuel, my engine 4 strokes a little, is it because I use to much oil? Thank you for the video
Normal. see this video: ua-cam.com/video/Mktwz0CCKsc/v-deo.html
@@HughesMotorized Thank you, wishing you all the best
I run 40:1 but I noticed that my spark plug is black. Why? I’ve ran through 5l through my tank so far. Also I’ve been using 2 cycle boat oil, is that ok?
Boat engines are water cooled. You want 2 cycle oil for air cooled. You might be running rich. I assume it's a 2 stroke?
Can you use synthetic during break in? Walmart had no non synthetic so I ran one tank of synthetic
No big issue. Run what you have
At 4:35 my bike is broken in at still makes that noise still what should I do?
do you need to change to head bolts or will it be fine to leave them long term? please repley
I sugggest a better lockwasher and ditch the acorn nuts. See the vid on this page: hughesmotorized.com/upgraded-cylinder-head-hardware/
Is it best to space out the rides a few days or a week or is it cool if I do many short rides in a day or two
Several short rides are fine. Slowly bring the revs up, retorque the head after 3 or 4 rides then haul ass
I can never find that link down below I want some of those washers for my head

I'm just learning about Jet sizes and how altitude affects the carburetor. What size jet do you recommend for someone who lives in Colorado Springs. Approximately 6000-6500 ft above sea level. Thanks in advance!
Not sure. I'm at sea level and never jetted one. Get an assortment and do a plug chop
hey man i live in springs too! i tear ass on my bike around downtown and garden of the gods
POV : "Me nodding at my dad as he tells I don't know what I'm talking about"
my bike is fully broken in and is it better to use 87 gas or can I use 93 gas because in the Manuel it says to use 93 gasoline?
Use the highest octane because it’s a small engine, oil tends to lower octane a bit. Plus that tank for the bike is usaually half a gallon. it shouldn’t cost much to buy a gallon of 93 and mix a 40:1 ratio.
he mentions that the motor is aluminum, and to be careful how much tightening you do. This was very much noted in my brain because just earlier I was tightening a screw into the motor and the screw began to strip the thread of the motor as steel vs aluminum showed that steel teeth will eat the aluminum away. i was smart enough to put a lot of loctite on after that to compensate and find a good spot to make it stick. dont be like me and tighten too hard with a power tool on the weaker metal.
I still have my acorn nuts on mine but I found the perfect tool that were not stupid and that is a chainsaw tool but I'm going to take your advice I didn't give it no special mixture breaking into engine either
U know why my clutch came stuck out the box and won’t engage
I want to install a 80cc on my bike for food delivery, I make around 50 km daily, is it better a 2 stroke or a 4 stroke engine and how many cc? Please answer and great video , keep em coming 🐖
4 strokes are more reliable. You'll need to run heavy steel wheels w/ thick spokes and keep wheel bearings lubed and adjusted. A 50cc scooter would be better
@@HughesMotorized oh I see because I make like 50km on bike daily and I need a engine that doesn't let me down , but if I take a chance with the 4 stroke will it be able to handle it if I don't force it like drive with 25-30 km speed? Thanks for the answer 😊
What grade of gas should i use?
If your engine is a high compression one and you get detonation/pinging then premium might help. If the engine can run on regular (no pinging or detonation) then it will normally make more more power than on premium. You should always run the lowest grade you can and not get detonation/pinging.
What’s better about the 40:1 mixture than the 20:1 or 16:1?
Too much oil builds carbon in the cylinder, and wastes oil
30:1 should be perfect
This man is a bloody genius! He definitely has the knowledge and wisdom of these little China doll motors. Bravo 👏
Awww shucks. Thanks for watching!
This thing is great 👍 6:02
HOW DO I GET THESE PARTS OFF YOU AND WILL IT WORK ON A 100CC MOTOR ???
I only sell tesioners, cables and Belleville washers. I get my parts off eBay and Amazon myself
Why’s 40:1 better then it’s telling me 20:1 for first 50 miles then 16:1 does 40:1 make it last longer?
Too much oil increases carbon build up and wastes oil
About how long does one of these engines last? Can you ride these for about 25-30 miles one way twice a day?
Yes and no. Youll get flats constantly, and have frequent breakdowns. Bicycles are not made for that demanding use. Car or motorcycle
@@HughesMotorized exactly and bicycles aren't meant for having motors either I finally got my 2 stroke going and I must say its fun but I don't get crazy with speed
If you wanna ride a motor vehicle get a motorcycle riding a motor bicycle is fun but it ain't something to do daily I have one and I also have an e bike too I'd pick the e bike more
My exhaust keeps falling off? Is that bad to run it without one?
You want backpressure. Running without might harm piston after awhile
Fix it
I’m definitely that dufis that starts it and revs it up. Just can’t help n I try so hard lol
During the break in period would I be able to bike 7km to work and back but just don’t full throttle?
Go for it. Just don't stay full throttle for long periods is key. 2 strokes don't like that, especially when new
@@HughesMotorized Do I gotta mix the oil (around 40:1) every time i fill up the tank? And what kind of oil will be good enough, nothing too pricey? I think my dad has some different types of motor oil.
@@breezetix get a 1 or 2 gallon can and put in 3.2 oz of 2-stroke oil for each gallon. Do it every time unless you want to destroy the engine. I use the cheapest 2 stroke oil I can get at the auto parts place or hardware store
How do you properly break in a phantom 85? A HAMMER
That bad huh? I haven't ran one yet. I know they had some issues
@@HughesMotorized bro they deff are sweet when they work but yea they do
What does it mean when you give it full throttle in it bogs? And it seems like it Losing power
Called 4 stroking.You can lower jet size a little to lean it out
Thank you . Now I am having other problems with it now I give it gas it bogs back fires and dies .
@@mosesjohnston6630 tune your carb acordingly
@@mosesjohnston6630 if that doesn't work, check your float. You may have to pry the prongs up just a little. Mr. Hughes can tell u how to do it.
Chain saws, weed wackers, blowers don’t recommend massive amounts of oil for break in. 30:1 or 40:1 should be fine. Just keep varying rpms. Old engines used to require 10:1 regular motor oil before 2 stroke oil.
Exactly. Why waste oil and foul plugs
Oil ratios are most dependant on ring thickness. These bike engines have thicker rings than the majority of motorcycles. I totally disagree with 40:1. 40:1 may be ok for a hobbyist that only rides his bike every once in awhile. For someone like me that depends on it for transportation and rides every day a higher ratio is definitely needed. I run 16 to 1 all day everyday and my bike has been dependable for over a year. There has not been one day that I haven't rode my bike within this year.
I have a problem. I ran 40:1 and my plugs kept fouling out. I took off my filter, raised the needle 2 notches, and it got worse. I noticed a tremendous power loss, it wouldn't even climb a small hill. Seems like the longer the ride, the worse the power loss became. I put the needle back into its original factory position, increased my ratio to 5:1, and I changed my muffler gasket (it came with an orange metal ring). I think that was the original problem as far as power loss, cause it really improved the torque. I'm still getting very black spark plugs, however. And I ride fine for about 20 minutes or so, then out of nowhere it just dies with no warning. It starts back up right away, but I like opening that throttle up, and it's annoying to have it die on me every time I'm ready to haul a little ass. Any suggestions?
Idk man mine only has a tan plug
I have to increase my throltle slowly to get mine going fast
How much of the engine do I need to grease
Bevel gears, for sure. They barely come with any if at all most of the time.
@@Excalibur250 when I greased the gears on my motor..I put a lot of grease around the area where it needed it n it runs great 🙂🙂🙂
Have 2 new bikes can't get them to start. Not sure what else to do. Hold clutch pedal let go but never get it to start
Try turning your choke off
Check spark plugs first.
Maybe set the idle adjustment to factory
@@michaeldelay3925yes
My brand motor that I have calls for 32:1 I've also seen the same looking motor online that says 25:1 and now I've seen a lot of people online saying run 40:1???
40 to 1 all you need from day one. Toss the instructions in the trash
@@HughesMotorized Well I ran 32:1 like the manufacturer of this motor scooters told me to do, the motor flooded over the course of two days riding it and the top end went out piston rings shaved and shaved a part off the piston itself, maybe running 32:1 is what caused that?
@@nwsights6301 Poor quality control or improper assembly. Some even use 100:1 using Opti synthetic oil
@@HughesMotorized Huh gotcha, well the company is sending me a replacement motor free of charge so I'll see how that one goes and really break the replacement one in. Thanks for the tips for ratios!
How far can you go in distance during break in. I’m about through my 2L tank now. And also how often should you refill the tank during break in? Like should you fill just before it’s empty?
Short trips and check that everything is good, chain tight no loose hardware, especially the first few rides. Then go a mile or two. Retorque head after 4 or so rides. Fill tank as you wish. 40:1 mix
@@HughesMotorized one more thing. Is choke lever up or down?
@@HughesMotorized like is having it up open or closed?
@@colevisuals111 UP is for starting. Down is for running
40:1 is comical. When you started talking that way I ignored everything else..
Mine wont idle without throttle
And from my experience. Metal on metal is way better than rubber motor mount buffers
the reason they say use 20:1 is because MOST of the cylinder and rings are crap and they need the extra lube
more oil = more carbon buildup = more wear. Yes indeed. You are right, the cylinder linings are thinner lately. We are riding ticking time bombs.
bull you need to glaze the piston
once you get that smooth glaze all good 16 to one one tank
I do agree on the time for first run check it all
Hello. I have a problem where it seems to be bogged down are like a shake type thing. Like it wants to run but don't
What engine? Spark? Fuel?
this just happend to me i put airfilter on mine but when i had it on the engine couldn’t get started popped it off and it started right up
@@andrewlaguerre8312 you can jet it bit more lean and keep filter
Check the sprocket alighnment and the tensioner are in line because they can rattle and stall at low rpm
like And subscribed
I broke and frames
I use 50-1 most times
Me too.Do you use synthetic oil? High octane gas with no methanol is my preference. I'm still fouling plugs, I'm actually thinking of going up to 60:1.
@@michaeldelay3925 I just use the Walmart super tech I think it's called brand and no problems and I don't have any plug following problems however I did change my jet so that my bike was running a little bit leaner than from the factory.
I ran 16:1 for break in and now I run 30:1
48 50 80 and 100 cc's are they all 40 to one.
Yes
