@@robwatkins1547 man i used to race mopeds and we never had a class for stock 50cc just only modded i raced my own bws 50 with polini 70cc big bore r1200 exhaust stage 6 oversized and clutch stage 6 intake PHBG delorto 21mm ps and thats it and i was put in classes with 70 to 80cc and i blew my motor within 2 hours of racing but i had 60 hours on the top end already but it was fun racing it so small so nimble and driving it around its so loud get alot of looks and i live in alberta so noone does what i do to their mopeds but i stopped when i was 19 i just felt kinda dumb on it now i just store it in my parents garage blown up sad life for it but maybe one day ill have kids and when their 14 ill still have that moped and ill fix it and make it work good for once
When these came out in '87 I was racing an FZ600 at Willow Springs in A.R.R.A. I bought one as a pit bike and daily rider since my FZ was no longer street legal. A friend of mine hooked me up with D&D Pipes and SUDCO INTL who distributes Mikuni carbs and together they made a proto-type expansion chamber and changed my carb from a 16 to 22mm and added a K&N filter and gearing change. When the pipe was installed it went from barely lifting the front wheel shifting into 2nd to a little longer wheel lift. When everything was finished it did just over 60 and could wheelie 2nd gear as long as I wanted it to. In comparison I have a 2023 XR150L that barely hits 60 with my fat butt on it. I would put my leathers on and ride the YSR throughout Griffith Park knee dragging or on Mulholland. I even had a Ninja 500 pass me on time and the next turn I passed him back and never saw him again, lol. Such a fun bike. When I moved to Northern CA in the 90's they were racing these at Prairie City OHV on a go cart track.
I always appreciate you letting viewers know what you paid for an item. Too many times, other videos say they got a "good deal," but never say what they've spent. It's reassuring to know that good deals do still exist.
This is the perfect reason to have a bike lift. When I was in the business, I didn't buy one for the longest time, but once I got one, I couldn't imagine working on a bike without it. The level of convenience was off-the-charts.
I bought one of these out of the showroom on a whim and it was an absolute bang for the buck bargain. I worked at a car dealership and had the pinstriper add Stripes between the red and the white on the tank. I tode it for about 2500 miles along Coastal Orange County and smiled every one of those miles. I eventually sold it back to the dealership and put that money towards a truck. At 6 ft 2 I looked a bit ridiculous on it, but I still regret selling it.
Back in 1981 I got a Yamaha FS1M, the restricted version, I was 16 but had ridden and mended field bikes for years. I set to work on the little Yamaha to wring out as much power as I could. I had boxes full of pistons and barrels, carbs and disc valves and heads that had different compression values. I mixed and matched and experimented over a year or so and got it to hit 72mph, I was getting bigger and heavier as I was still growing back then so the gains were getting smaller, the biggest increase came from the Micron exhaust and a jetting increase. I miss that little bike..
Interesting fact little quirk about the ysr there's only one fork spring in the fork tubes. That's why it dives hard in coners and has front brake dive. There awesome bikes.
6 grand for a 50cc I don't care restored or not it's still a 50cc unbelievable the stretch. Tops showroom restoration. These shouldn't surpass 2 grand maybe some change. It's not worth 6-7 thousand dollars you people are Koo Koo
Dude I’m a 50 yo diesel mechanic. Watch all your stuff. This is my favorite you’ve done. We could legally ride those on the street at 15 1/2 where I grew up before we got our drivers licenses because they were 50cc. We had so much fun on em. Super cool! I ride my liter rocket as much as I can. All started with a YSR. Keep up the good work. 🤙
Cant believe you got one of these! And for 1200! Amazing find! In mint condition you can get up to 14000 from the right collector. Looks like a scaled down YZR500. Too cool bro!
@AL4N. with how healthy and original this bike is, I think he has no problem getting 4 to 7k from the right buyer. It is a very healthy engine and great components!
This was exciting to see Joe ‘s enthusiasm in it. Have you noticed how his luck has changed lately? He is finding himself with honest sellers . Will it continue? I always learn something about repairs every week. 😊😊😊
Clutch lever should have more free play. It sounds like its preventing it from fully engaging the clutch. Loosen it back like it was. See if that helps.
I'm only a few minutes in... when you said it was a 50, I though how could a bike that big be only a 50? Then I saw you getting it off the truck... I chuckled!
The YSR was available in 50cc, 80cc and 125cc and was a bike to introduce new riders to sports bike riding. Obviously, the engine size dictates the performance that in the small size was 'modest' There was a genuine market for these bikes back in the day as there was for the likes of the C50/C90.
In Western Europe, every youngster was allowed to ride a 50cc moped from the age of 16. In the 1980's Yamaha sold the RD mopeds, with a 4 speed manual gearbox. For the Dutch market (and probably others) they were detuned with a restriction in the intake manifold as well as the exhaust pipe. I lived 10 km from the Belgium border, where they had no restrictions at all. So that is where we went for our go fast bits. In Belgium, a Yamaha RD50DX was sold, that came with a 20 mm mikuni carb stock, and went like the clappers. The factory spec was 6.25 HP. On first glance it looked exactly the same as the RD50M (Dutch detuned version), but the engine was quite different. It had a 4 reed intake instead of the 3 reed, a bigger carb, way bigger transfer ports, a double exhaust port and the cylinder was alu instead of cast iron. They also had a 5-speed box. The cooling fins on the head and cylinder were also slightly larger. I shoved that engine in my 50M, and on top of that made it a monoshock rear suspension and also a rear brake disc. I loved that bike! With a bit of tailwind I could reach 100 km/h, at 11.000 rpm. Unfortunately we were only allowed to ride on bicycle paths in those days.... So when you removed the reed valve block from the engine, I could see that it is a very similar setup as the RD50MX. I wish our mopeds looked as flash as your YSR though!
New Subscriber, I was a state licensed motorcycle mechanic for years so I can see that you know what your doing, good for you, your videos are vary good for teaching, two thumbs up
I have one of these. Mine is a Japanese market bike so a few differences (smaller indicators, kmh speedo, no kill switch, etc). Great fun. Furthest I have ridden it was about 35 miles each way and by then I was a bit sore! I took it down a drag race strip and it managed 23.57 seconds at 50mph. Local bike shop had a dyno day and I took it - it managed 5.9hp. Did take some bodging to get the rear wheel to reach the dyno roller. When I first bought it I did consider some of the Team Calamari Racing tuning bits, but decided as it was flat out almost everywhere reliability was more important (plus if I want to go faster I will just take a different bike). I did fit fibre reeds as less likely to cause major damage if they fail (presume yours have been swapped also). I am running with the oil pump with no issues at all (I trust the pump way more than I trust premix). Being Japanese market bike it has a speed warning light that comes on at 40kmh (25mph). But once the needle goes a bit off the end of the speedo the warning light stops (as though it has had enough of you ignoring it). Once you get off the end of the speedo the accuracy is laughable (the bike gains a tiny bit of speed and the needle moves about as far as a 10kmh speed marking). If I use it for the local christmas toy run the clutch noticeable suffers and needs adjusting afterwards. They vibrate a bit. Enough on 1 ride for the choke knob to vibrate out of the carb. Also lost the end of the indicator switch once. Think the fuel taps Yamaha now list for the YSR are too large to fit (they catch on the frame) Rather than folding the footrest up and the kickstart out I tend to find it easier to push start it. The battery covers do go walk about easily (there is a wave washer under the fastener - with age it loses its spring so the fastener can come undone easily). I spent ages with a CAD package and drew up a replacement (a guy in the USA is printing and selling these - with my permission)
As a teenager, some of my friends had Honda MB5s. Quite a different bike from this YSR but similar drivetrain and so darn cool. Joe you've been finding some real gems lately! Keep up the great videos 👍
I got a knee down for the very first time on one of these back in the 80’s. My friend and used spend hours lapping an abandoned go kart track with one. Such a cool little bike.
I had one too,when I was 17 I bought it from an old man for £70 in 2000 had 814 miles on the clock, had a chrome micron exhaust on , and dt 50 swing arm , put a rxs 100 carbon on it and changed the sprocket from 38 to 36 , it did 83mph ,had so much fun with it as y first bike on the road, sold it for £300 and regretted it ever since Got my first blackeye after riding at 75-80 mph, and with my visor open, a bee 🐝 hit the bone just below my eye 😂😂
I can just imagine that thing sitting under the Christmas tree a handful of times in its life. Maybe it will live to sit under a Christmas tree again this year.
One year at the USGP at Laguna Seca Yamaha had set up a little course in the infield with a bunch of those. We got to bump shoulders with each other going for the lead. I love Yamaha. They make the fun stuff.
Another Great Score for Joe. Your the Man when it comes to figuring out these bikes noone else can and has given up only to sell them to you for a great price. Good job!
Have 2 and a bought new an '89 DT50/LC. Yup LC stands for Liquid Cooling, 7.4 hp, 6 speeds, monoshock, speedo TACH and temp gauge, grown up ergonomics, 31" seat height, 19"/17" wheels and it being the only "liquid cooled" two stroke enduro 50 state legal ever sold in the US of any make then or since. Have a framed 63 in a 45 speeding ticket (tooth up on the countershaft sprocket). Both DT's (one bumblebee and one red/white XT style) are turn key, get ridden daily and are fully insured etc. Bumblebee has 11,000 miles and 35 years on it with the original piston/rings. I never see a YSR with more than 4k that's been unmolested. People think it's a 175 euro import.
Sweet !!!!!! Calamari pipe “if you can find one”, carbon reeds, 13 tooth sprocket, 28mm carb mix you’re own gas. 63 mph 20/50 castrol a must. Heavy clutch spring kit
Oh the childhood memories my buddy used to own one of these in the early 90’s when I used to live in Jamaica. That’s how I learned how to ride his was the black and yellow color scheme. His older brother owned a CBR1100 blackbird and it just sat there. Thanks for the flashback.
I owned 2 of these when I lived in Hawaii from 90-98. One was a 89 that was red/white like yours and a 91 that had the rare metallic charcoal gray/red. I eventually parted out the white one. I fully built the 50cc engine, swapped occasionally to my built 80cc engine to race the 91. Team Calamari on CA has all you need to trick or restore it to something really nice. Luckily, I still have pictures of the 91 in its restored and being raced condition. I sold it before I left Hawaii, I’d do anything to get it back today.
Yep, just searching did anybody else hear same. I bet that fuel filled oil did not do a favor to the plates, might work if you use some wet clutch dedicated oil insted of regular one!
I used to own one of these identical to this one. I rode that thing everywhere. It was the coolest little bike I ever owned. When I got mine I traded a guy an "in pieces" kx125 and he was tickled and so was I. Mine was like new. Not a scratch on it. Man, I miss that little bike. Nice one man!! 👍👍
I've never seen one of those before. It's in pretty good condition, and runs great. At first I thought it was kinda goofy looking because the tank looks huge compared to the rest of the bike, but after looking at it for awhile, I got used to it. It would be cool if you can find a front fender at a reasonable price. It changes the look of the bike quite a bit.
I had an '87. Got it for Christmas in '86 and drove it at 14 with a youth MC license to my summer job the next 2 summers. Sold it to a good friend and it was lost in a garage fire sometime in 1990. I literally drove this thing everywhere. I would drive out through the Wichita Mountains in SWOK and up and down Mt Scott. 4-5 times every Sunday.
A blast from the past lol, it looks so awesome still, for a 50cc. I had a Suzuki RG50F at that time, 1987 model and I loved my bike. Awesome to see it and it didn't take more than a few kicks, wow.👍😂❤️
What a score. We use to race them ysr50s up here in Ontario Canada and they also had the ysr80s. Fun fact you cam stuff an IT175 motor in the ysr50 my buddy did it and let me tell you driving that thing in the hwy was crazy. But yes they were street legal. I have been trying to find one for years for a good price.
Smart man bench testing the carb. I don't know how many carbs I wrestled back on to the bike and found out they were still leaking. It's so much easier to check for leaks before you bolt it on the bike.
one thing I noticed on the carb immediately was the rust color on the inlet 23:00 handheld impact driver with a good Phillips bit for the case screws are amazing 32:10 "dissimilar metal corrosion" happens on tractor/trailers when people repair the side skirts that are aluminum with unprotected steel bolts instead of aluminum rivets. if you see it, looks like foamy white dust with bigger bubbles. there has to be a different screw material in order to prevent it
24mm carb itty bitty lol , may have nos carb in storage if needed , need to go through nos parts and catalog them,, have sold some parts , had put a stage 3 kit in mine yrs ago 80cc wiesco piston 35 mm carb etc, zoom zoom.
When I attended MMI in Phoenix AZ, they had dozens of the YSR’s! We modified them in our 2 stroke performance class! Got some crazy HP out of them on the dyno!
Hi Joe - another masterpiece! Thank goodness when you were looking for a property you managed to find a housing development who were all massive fans of motorcycles, in all their various shapes and sizes, because your neighbours must LOVE you! That screaming little fifty is a joy to hear - surely she’s going to be your Xmas present to yourself…? Or do you have something 2 wheeled that’s even sweeter?
I have an Aprillia rs 50 that's been outside in the weather for at least two years. The electrics are dead but its all their and looks pretty straight. This video is a step by step guide for me to get started on it, cool video hit the like button.
Gotta be one of the coolest 50cc bikes. That bike sounded awesome, and fun to ride. Good job getting it going, that's the best part of the videos. Getting the machine going to its former glory after sitting for who knows how long.
BRAVO on the variety! Great find, now let's tear it apart. Interesting looking frame - who knew? Thank you again for all the teaching and learning moments
Another very good fix there. Just by checking the spark plug(s), carburetor , oil and compression can make a very big difference on whether it works or not.
For 6v I recommend to replace the battery with a sealed one used for battery backups. They are affordable, last a lot longer, wont spill and have a bit better power density. They are affordable only difference is it uses f1 connectors. This is the battery I use on my Honda CT90
Is it me or is that clutch on its way out? Possibly over adjusted, ? Love the video, your method of getting to the problem is fantastic, keep up the good work👌
I have been watching his channel for years and there is three common things he does. 1) this is the best deal ever 2) he revs the crap out of everything when it’s cold 3) he winds the clutch out and hammers on it. Dont get me wrong I like his channel but I always find myself say these things. Wow you always get stuff crazy cheap, why are you winding the crap out of that cold engine and man you can’t shift.
fun to watch this as this has the same engine as Yamaha DT50MX and i've been restoring my old Yamaha DT50MX that i got when i was 16 i'm 34 now the only thing i hate about that engine is the clutch lever mechanism it burns out so fast
Could you create a video explaining basic dirtbike components, such as swing arms, tensioners, carbs, and exhausts? This would be helpful for new mechanics to understand what faulty parts look like and the symptoms they produce.
Pretty sure you could fix the MARS ROVER with little to no parts..................much respect for your troubleshooting skills, keep up the great content......side note: /mechanic hack.......strap and or glue a magnet on the back of your compression gauge so you can attach to the frame or block when trying to read the gauge when kick starting or trying out the starter. I've noticed you struggling trying to get a reading on camera when diagnosing compression in many of your videos. I've done this to both my multi-meter and gauge and it helps out.
Wicked wee bike mate, back in the day we used to ditch the 50cc and shoehorn a YZ 125cc engine into them,but that was back when you could buy one for £50/$65 keep it original clean it right up and make a few quid off of it chap.
Awesome score. In '89 2 of my friends had those. 1 was stock 1 had a yz 80 engine. Unfortunately the 80 wasn't fast like I hoped. It's too bad the gsxr 50 was a four stroke. Suzuki dropped the ball on that one.
nice work mate, i have seen a lot of your videos, the only thing i wish to see for you safety it's a vacuum for that engine smoke, like they use on DOT, or anual inspecion on cars, a big flexible tube to put on exaust and all smoke go outside, have a nice day, i hope you understand what i just write
Fairly common anywhere there is a decent road course go kart track. If you really want a rare (and far superior) 50cc mini GP bike, the Honda NSR50 is the gem to have.
wow that sounds and almost looks like my RD400 same custom fairing and solo seat but with the stock tank! it looked great and was fast as hell lol that little bike brought back memories thanks my friend!
I believe I can give you some tips bout that bike. Check if it is 2 stroke engine. Mix oil for gas has separete tank and pump. I think had a 92 yr. Great memories
This bike is a TZR50 mini bike with the very nice DT50 and RZ50 6 speed bottom end and would make for a very capable racer if you get the liquid cooled cylinder or even maybe one of those 80cc Metrakit or Athena all aluminium cylinder with bigger carb and exhaust. And the LC clutch cover with the water pump and ancillaries necessary to convert the engine. I would be very wary of the way the bike was recommissioned this time though as it needs a lot restoration done to get some ease of mind . Any way nice find. All you need now is a kid to ride it.🙂
Thanks for the memories. Remember seeing these around the Univ of Minnesota (Minneapolis). Thinking adults riding Playskol My first motorcycle. Riders knees nearly scrapping ground.
Bikes and Beards on you tube got a whole container full of different Japanese bikes in class couple of days. One of which was the same one you have only with all Japanese designations pretty cool.
I had a yamaha DT50 as my first (legal) on road bike. But the Rd 125 LC replaced it with was great fun. My older brother got an RG 250 Skoal Bandit at the same time. Years later my other brother bought an RG500, which was f'in insane!
The memories must be flooding in lol, different hairstyle, not much stubble yet, baggy clothes and your father shouting in the background because you're revving it lol, sound familiar?😂👍
bring back memories , i purchased 2 of these foe $3000 CDN in 1990 still in the crate , wish i knew they would be worth so much today! Used to ride them to the nightclub and coat check them so they were not stolen,,, good times!!!!
Love that there’s no music, no extra bs. Just straight wrenching , love it

spounds like clutch plates need some love
I wondered if I was hearing those gear changes right...a "Rolls Royce" auto box "slur" between gears....but it was never mentioned????
Yep, I just said that.
That's what I was thinking. It's only a 50 but shouldn't sound like she's always winding in all areas.

Once you get off the end of the speedo the accuracy is laughable (the bike gains a tiny bit of speed and the needle moves about as far as a 10kmh speed marking).
If I use it for the local christmas toy run the clutch noticeable suffers and needs adjusting afterwards.
They vibrate a bit. Enough on 1 ride for the choke knob to vibrate out of the carb. Also lost the end of the indicator switch once.
Think the fuel taps Yamaha now list for the YSR are too large to fit (they catch on the frame)
Rather than folding the footrest up and the kickstart out I tend to find it easier to push start it.
The battery covers do go walk about easily (there is a wave washer under the fastener - with age it loses its spring so the fastener can come undone easily). I spent ages with a CAD package and drew up a replacement (a guy in the USA is printing and selling these - with my permission)
As a teenager, some of my friends had Honda MB5s. Quite a different bike from this YSR but similar drivetrain and so darn cool. Joe you've been finding some real gems lately! Keep up the great videos 👍
I got a knee down for the very first time on one of these back in the 80’s. My friend and used spend hours lapping an abandoned go kart track with one. Such a cool little bike.
There was an adult class roadracing those in the late 90's. It was a blast to watch, cheap and safe for the racers.
Sweet little bike. I had a Yam RD LC 80 40 yrs ago. Mad revving little thing. 10Hp and 78kgs dry.
I had one too,when I was 17 I bought it from an old man for £70 in 2000 had 814 miles on the clock, had a chrome micron exhaust on , and dt 50 swing arm , put a rxs 100 carbon on it and changed the sprocket from 38 to 36 , it did 83mph ,had so much fun with it as y first bike on the road, sold it for £300 and regretted it ever since
Got my first blackeye after riding at 75-80 mph, and with my visor open, a bee 🐝 hit the bone just below my eye 😂😂
I can just imagine that thing sitting under the Christmas tree a handful of times in its life. Maybe it will live to sit under a Christmas tree again this year.
I'm from the CHI and I can say I have only seen 1 of them running amazing that is cool to see again 🎉🎉
i wish i had one of these back in my learner days... would have been the coolest kid in Vietnam
One year at the USGP at Laguna Seca Yamaha had set up a little course in the infield with a bunch of those. We got to bump shoulders with each other going for the lead. I love Yamaha. They make the fun stuff.
My buddy has one of those. Clean and runs. It sat in my shed for about 5 yrs. He came and got it out last summer. Never got a chance to ride it
Easy check on float valve is to blow on gas inlet, it should flow. Flip over and inlet should be blocked.
I vaguely remember these in catalogs for the 89 Yamaha lineup. I had a 1987 YZ125 in 1989 and I always got the catalogs.
Cool to see you found another one, I remember when you and chuck would race the 50 against the 80 😂
got 2 of these one still in crate. , bought out 2 dealers in the 80's fun rides
Well ALLLLLLL RIGHT !!
@@MrBumbles2 OMG!!! Still in the crate?? That’s awesome!!!
Nice
@@blkcab911 Non ça ne sert à rien, un engin a moteur est fait pour rouler.
Yeah, I’m sure it’s sitting right beside the pink elephant and the flying pig!
Another Great Score for Joe. Your the Man when it comes to figuring out these bikes noone else can and has given up only to sell them to you for a great price. Good job!
Man, I remember ripping a couple of these around back in the day. They were super fun.
Man that is a great looking bike. Great lines and paint scheme.
Have 2 and a bought new an '89 DT50/LC. Yup LC stands for Liquid Cooling, 7.4 hp, 6 speeds, monoshock, speedo TACH and temp gauge, grown up ergonomics, 31" seat height, 19"/17" wheels and it being the only "liquid cooled" two stroke enduro 50 state legal ever sold in the US of any make then or since. Have a framed 63 in a 45 speeding ticket (tooth up on the countershaft sprocket). Both DT's (one bumblebee and one red/white XT style) are turn key, get ridden daily and are fully insured etc. Bumblebee has 11,000 miles and 35 years on it with the original piston/rings. I never see a YSR with more than 4k that's been unmolested. People think it's a 175 euro import.
Sweet !!!!!! Calamari pipe “if you can find one”, carbon reeds, 13 tooth sprocket, 28mm carb mix you’re own gas. 63 mph 20/50 castrol a must. Heavy clutch spring kit
Oh the childhood memories my buddy used to own one of these in the early 90’s when I used to live in Jamaica. That’s how I learned how to ride his was the black and yellow color scheme. His older brother owned a CBR1100 blackbird and it just sat there. Thanks for the flashback.
I begged my dad to buy me one of these….!!! Nice work getting that running!! Thanks for sharing 👌🏽👌🏽
I owned 2 of these when I lived in Hawaii from 90-98. One was a 89 that was red/white like yours and a 91 that had the rare metallic charcoal gray/red. I eventually parted out the white one. I fully built the 50cc engine, swapped occasionally to my built 80cc engine to race the 91. Team Calamari on CA has all you need to trick or restore it to something really nice. Luckily, I still have pictures of the 91 in its restored and being raced condition. I sold it before I left Hawaii, I’d do anything to get it back today.
I'm 50 and use to have one, brand new !
Loved it, pretty special doing 65mp/h :)
you got a gem here !
Sounded to me like the Clutch was Slipping when Shifting Gears.
Yep, just searching did anybody else hear same. I bet that fuel filled oil did not do a favor to the plates, might work if you use some wet clutch dedicated oil insted of regular one!
I used to own one of these identical to this one. I rode that thing everywhere. It was the coolest little bike I ever owned. When I got mine I traded a guy an "in pieces" kx125 and he was tickled and so was I. Mine was like new. Not a scratch on it. Man, I miss that little bike. Nice one man!! 👍👍
I've never seen one of those before. It's in pretty good condition, and runs great.
At first I thought it was kinda goofy looking because the tank looks huge compared
to the rest of the bike, but after looking at it for awhile, I got used to it.
It would be cool if you can find a front fender at a reasonable price. It changes the
look of the bike quite a bit.
YESSSSSSS!!!!! YSR BABY!! These things are awesome!! I rolde one on the street for a few weeks years ago. So many turned heads LOL.
Kick starter needs adjusting so it doesn't hit the fairings ❤ great bike great video as always 😊
I had an '87. Got it for Christmas in '86 and drove it at 14 with a youth MC license to my summer job the next 2 summers. Sold it to a good friend and it was lost in a garage fire sometime in 1990. I literally drove this thing everywhere. I would drive out through the Wichita Mountains in SWOK and up and down Mt Scott. 4-5 times every Sunday.
A blast from the past lol, it looks so awesome still, for a 50cc. I had a Suzuki RG50F at that time, 1987 model and I loved my bike. Awesome to see it and it didn't take more than a few kicks, wow.👍😂❤️
Time for a full resto Joe. Had one in 1991, funnest thing on 2 wheels.
Joe, second video in a row where you ate the bear! Congrats! My 1960 Puch (Allstate) moped was a 2-speed and maxed out at 34 mph!
What a score. We use to race them ysr50s up here in Ontario Canada and they also had the ysr80s. Fun fact you cam stuff an IT175 motor in the ysr50 my buddy did it and let me tell you driving that thing in the hwy was crazy. But yes they were street legal. I have been trying to find one for years for a good price.
Smart man bench testing the carb. I don't know how many carbs I wrestled back on to the bike and found out they were still leaking. It's so much easier to check for leaks before you bolt it on the bike.
You have been on a roll lately. Getting your machines back in service without pulling your hair out. Even the wife got a new toy.
one thing I noticed on the carb immediately was the rust color on the inlet 23:00
handheld impact driver with a good Phillips bit for the case screws are amazing 32:10 "dissimilar metal corrosion" happens on tractor/trailers when people repair the side skirts that are aluminum with unprotected steel bolts instead of aluminum rivets. if you see it, looks like foamy white dust with bigger bubbles. there has to be a different screw material in order to prevent it
The joy in your chuckle with each success is the best!!
24mm carb itty bitty lol , may have nos carb in storage if needed , need to go through nos parts and catalog them,, have sold some parts , had put a stage 3 kit in mine yrs ago 80cc wiesco piston 35 mm carb etc, zoom zoom.
Looks like a full size bike with no one standing by it.
Dont forget to sleep once in awhile Joe..
When I attended MMI in Phoenix AZ, they had dozens of the YSR’s! We modified them in our 2 stroke performance class! Got some crazy HP out of them on the dyno!
It was back in 1991.
I don't know if you've ever had a Honda MB5, but that is the most fun I've had on a ridiculously slow bike!!
Sounded like the clutch was slipping each time you let it in after changing gear.
Hi Joe - another masterpiece! Thank goodness when you were looking for a property you managed to find a housing development who were all massive fans of motorcycles, in all their various shapes and sizes, because your neighbours must LOVE you! That screaming little fifty is a joy to hear - surely she’s going to be your Xmas present to yourself…? Or do you have something 2 wheeled that’s even sweeter?
I have an Aprillia rs 50 that's been outside in the weather for at least two years. The electrics are dead but its all their and looks pretty straight. This video is a step by step guide for me to get started on it, cool video hit the like button.
In the early 90’s everyone rode these in Los Angeles, wow I haven’t seen them since 😮, keep this in the collection 👍🏽
He already had 2 when he first started the channel let's see what he does with this one
Gotta be one of the coolest 50cc bikes. That bike sounded awesome, and fun to ride. Good job getting it going, that's the best part of the videos. Getting the machine going to its former glory after sitting for who knows how long.
You seriously need to get a lift table Joe, you’re still young, save that back buddy!
BRAVO on the variety! Great find, now let's tear it apart. Interesting looking frame - who knew? Thank you again for all the teaching and learning moments
Another very good fix there. Just by checking the spark plug(s), carburetor , oil and compression can make a very big difference on whether it works or not.
Good job figuring the wiring out. It's a mini RZ.
Top little classic,done really well lately Joe,needed it after them atv rebuilds,Great find this one😎
I hate those ATV videos, unless it's a 2-stroke ATV.
Nice test rip! Your clutch could at least stand some heavier springs in it, and turn the idle speed down! You got a good score, Joe, thanks man!
Hi, Just for your info. It is 2 volts per cell. A 6 volt battery has 3 cells and a 12 volt battery has 6 cells.
For 6v I recommend to replace the battery with a sealed one used for battery backups. They are affordable, last a lot longer, wont spill and have a bit better power density. They are affordable only difference is it uses f1 connectors.
This is the battery I use on my Honda CT90
Do you have a link to the battery? I have a DT 50 and uses 6v. Would like a better battery.
I had the exact same one . Loved it ❤ I put a 1/2 hole in the expansion chamber and this bike flew.
I love your talents especially electrical, most inspiring and inculcating.
Is it me or is that clutch on its way out? Possibly over adjusted, ? Love the video, your method of getting to the problem is fantastic, keep up the good work👌
I've wondered this on a few videos. Not sure if it's him riding the clutch or what. Either way this is a nice find
I have been watching his channel for years and there is three common things he does. 1) this is the best deal ever 2) he revs the crap out of everything when it’s cold 3) he winds the clutch out and hammers on it.
Dont get me wrong I like his channel but I always find myself say these things. Wow you always get stuff crazy cheap, why are you winding the crap out of that cold engine and man you can’t shift.
That thing is amazing. I never even knew they made them Great content as always Joe
fun to watch this as this has the same engine as Yamaha DT50MX and i've been restoring my old Yamaha DT50MX that i got when i was 16 i'm 34 now the only thing i hate about that engine is the clutch lever mechanism it burns out so fast
If the transmission oil on a 2 stroke smells like gas, you've got a problem!
Keep up the good work learnt so much from these videos 👍👍
Absolutely true!
A little humdinger, nice score. Sounds great.
40:42 "Carb is not leaking at all" Carb: 💧
Could you create a video explaining basic dirtbike components, such as swing arms, tensioners, carbs, and exhausts? This would be helpful for new mechanics to understand what faulty parts look like and the symptoms they produce.
Always wanted one of these. Never bought one though. Loved this video. Thanks Joe!
Pretty sure you could fix the MARS ROVER with little to no parts..................much respect for your troubleshooting skills, keep up the great content......side note: /mechanic hack.......strap and or glue a magnet on the back of your compression gauge so you can attach to the frame or block when trying to read the gauge when kick starting or trying out the starter. I've noticed you struggling trying to get a reading on camera when diagnosing compression in many of your videos. I've done this to both my multi-meter and gauge and it helps out.
I wouldn't trust that oil pump i would premix to be safe for sure
Why. It is a really reliable system. Just put oil in the little tank.
@lennartengel1971 Everything is reliable until it's not
😂 premix everything😂 u can do that with your bike lol not taking that risk. Better safe than sorry those are known to fail and do dmg
Wicked wee bike mate, back in the day we used to ditch the 50cc and shoehorn a YZ 125cc engine into them,but that was back when you could buy one for £50/$65 keep it original clean it right up and make a few quid off of it chap.
Awesome score. In '89 2 of my friends had those. 1 was stock 1 had a yz 80 engine. Unfortunately the 80 wasn't fast like I hoped. It's too bad the gsxr 50 was a four stroke. Suzuki dropped the ball on that one.
nice work mate, i have seen a lot of your videos, the only thing i wish to see for you safety it's a vacuum for that engine smoke, like they use on DOT, or anual inspecion on cars, a big flexible tube to put on exaust and all smoke go outside, have a nice day, i hope you understand what i just write
Fairly common anywhere there is a decent road course go kart track. If you really want a rare (and far superior) 50cc mini GP bike, the Honda NSR50 is the gem to have.
wow that sounds and almost looks like my RD400 same custom fairing and solo seat but with the stock tank! it looked great and was fast as hell lol that little bike brought back memories thanks my friend!
I believe I can give you some tips bout that bike.
Check if it is 2 stroke engine.
Mix oil for gas has separete tank and pump.
I think had a 92 yr.
Great memories
This bike is a TZR50 mini bike with the very nice DT50 and RZ50 6 speed bottom end and would make for a very capable racer if you get the liquid cooled cylinder or even maybe one of those 80cc Metrakit or Athena all aluminium cylinder with bigger carb and exhaust. And the LC clutch cover with the water pump and ancillaries necessary to convert the engine. I would be very wary of the way the bike was recommissioned this time though as it needs a lot restoration done to get some ease of mind . Any way nice find. All you need now is a kid to ride it.🙂
Thanks for the memories. Remember seeing these around the Univ of Minnesota (Minneapolis). Thinking adults riding Playskol My first motorcycle. Riders knees nearly scrapping ground.
Bikes and Beards on you tube got a whole container full of different Japanese bikes in class couple of days. One of which was the same one you have only with all Japanese designations pretty cool.
I had a yamaha DT50 as my first (legal) on road bike. But the Rd 125 LC replaced it with was great fun. My older brother got an RG 250 Skoal Bandit at the same time. Years later my other brother bought an RG500, which was f'in insane!
The kick is not supposed to sit like that on the fairing, can you please rotate it counter clockwise on the shaft? That will make me so happy haha..
The memories must be flooding in lol, different hairstyle, not much stubble yet, baggy clothes and your father shouting in the background because you're revving it lol, sound familiar?😂👍
bring back memories , i purchased 2 of these foe $3000 CDN in 1990 still in the crate , wish i knew they would be worth so much today! Used to ride them to the nightclub and coat check them so they were not stolen,,, good times!!!!
