This bike has been a struggle. I spent hours working on it behind the scenes. Locating parts for it was also not easy! Please SUBSCRIBE and LIKE the video if you enjoyed! It really helps me out a lot! Check out my Instagram: 2_vintage_ Thank you for all the support! I read all the comments and I love getting feedback from you guys!
When you get it running properly that bike goes pretty fast, i remember my neighbor had one back in the day. Dad had a 73 Honda cb 200 twin at the same time. It was a 4 stroke,
As an rd200 owner the main issue is the fact you have not got the ignition switch. The starter is also the generator and the position of the ignition switch decides what mode it is running in (there is an emergency start mode but it bypasses the voltage regualtor and will just drain the battery). the wiring looks almost identical to an rd200 so i would use it as a basis. As for the cylinder that's not running well, it would most likely be a leaky crank seal allowing air into the crank case and leaning the mixture out, this would eventualy result in a holed piston. You are however almost 98% there wont take a great deal more to get her going good!
This isn't an RD200. This is a YCS5E. The problem is the electrics. I had one and had to change the entire generator/starter rotor and field winding and the control system. The taper on the RD 200 crankshaft, is different so the new rotor had to be bored to a new taper. The YCS5 was, unfortunately not a successful product for the otherwise awesome Yamaha company.
Sounds like it just needs a good carb clean/rebuild... I’m a fellow 2 stroke nerd and a good clean carb solves a huge amount of frustration and troubleshooting.
I think it is running without the air filter, that's why it sounds weird and lean, the bores won't say in good condition for long without the filter, that's for sure!
@@Jacob_D167 The bike was designed to have an air filter, the bike in the video does not even have the rubber tubes that connect the air filter to the carbs so no it's not running an air filter. Even if I could not see that it's missing the air filter it is very easy to hear that its not running one.
OK, the piston and head damage indicates a likely lower end bearing failure, small pieces of a cage have come through the transfers and were pounded between piston and head, which has likely also compressed a ring land, sticking a ring and causing compression loss (125 is low), additionally the left crank seal is likely leaking compounding the performance loss, leaning the fuel/air mixture for the left cylinder (actually both due to the labyrinth center seal). the spring you replaced for the brush also needs to have preload so there is good pressure behind the brush....the preload cannot be done correctly without removing stator assembly to install. These brushes perform 2 functions, when 12 VDC is applied the starter spins the engine, and while running thes same brushes feed 12 VDC back to rectifier to help recharge the battery. Rebuild the engine (these are simple) repair whatever sent the debris to do piston damage and enjoy, these are fun machines. good luck!
there was no piston or head damage on this bike, you would have known this if you would have watched the whole video or payed any attention while watching
That kikker is supposed to be vertical so you have enough stroke. Points set at .012", firing at 1.5 mm before tdc, use dial indicator in spark plug hole & ohm points to find when open, adjust points backing plate for timing & points themselves for gap. Low speed cir in carbs still dirty, very small passages takes lots of soaking in mineral spirts to get clean. My dad had a Yamaha dealership for 20yrs I assembled so many of those & have a 1968 180cc twin the early version of that 200. We found old 125cc twin pistions would fit (with bore job) & makes it a 250, had one I used to road race, light & fast. Sorry you having so much trouble, those were great with the electric starter.
I know this comment/video is over a year old but I was hoping for some tips if you read this. I have a 72 cs5 I just acquired, starts great with the electric starter after I fixed the regulator but it won't charge. I've been reading the manual and bought some spare brushes in an attempt to fix it. Those will be here soon. What typically causes these bikes not to charge the battery? The armature is new to me as Ive never worked on a bike like this before.
Yes, that little block of carbon is a brush. To fix the kickstarter, you need to widen the slot in the round bracket that grips the splined shaft sticking out of the engine case. If you widen that slot (by using a Dremel cutting disk), the pinch bolt will be able to tighten the bracket onto the shaft more securely.
YEP! I know You have struggling with this one, because I have restored kind'a similar RD 125 year 1974 for five years. Locating and buying old-new stock parts or aftermarket new one parts is a huge task even if You're using EBay. If You want to cut the corners with the kick-start lever (like You did) it will end up with the same problem I had. After having ordered a new kick-start axle to replace the old and original damaged I also ordered a new kick-start lever. After installing them both and after some couple kick-starts try-outs, new axle was damaged to unrepaireble condition. The main reason was that they DIFFERENT number of GROOVES... Thanks to ever-eager-sellers from Asia! Finally I had ordered bth of them again - and after having sure they have same amount of grooves, it got better. Unfortunatelly, after having tried some efforts to get it start in summer 2024 the next problem I found were the bleeding valve seats (Teihin carbs). I have a new repair kit for Keihin carbs ordered from Holland, but their were no match although they were sold suitable for this specific model. After some struggles I managed to buy new fuel seats from importer - with a hair-raising price of 80 euros (maybe 90 US dollars a pair). There are still some electrical problems to solve.
Had one of these back in the day. Engine is basically two Engines in one. 1 carb, 1 coil , 1 set of points for each cylinder. You have to time each cylinder independently. Unless that's a 200cc or less. It doesn't have a starter. 250-350 cc didn't have starters. Throttle cable is 1 cable that is split into 2 in a sleeve below tank. If sleeve is Cock eyed then carbs aren't synced and one might be flooded. That's of timing is correct. Might need to lube sleeve and you'll be good to go. Look in carbs and see if slides are in same positions .
anything 200cc and above had starters, and you are totally wrong abouy the throttle and cables, and if you were paying attention to the video you would see that the slides were the same
@@robertweniger6194 Sorry, but you're wrong. The 250cc, 350cc,400cc starters weren't available. I bought all 3 new back in the day. You can tell by a video carbs are synchronized ? 😆 these bikes were notorious for weak coils, plus leaded gas was a recipe for a shitty running bike. 200cc had a starter because that size engine wasn't running in a racing class. The others were. If you were there you'd know this.
I am not being critical of you, in 1976 I started riding on a RD-400 and made all the mistakes and more that you could possibly make without blowing up the engine. Two strokes need to run through the air cleaner, by running it without the air cleaner boots it was running too lean. You also had the choke on while trying to ride it. it made all the sounds of a two stroke starved for gas. As for the electric starter and the Kick starter. You never had the kicker starter positioned to get a full kick. it was at the 9 o'clock position instead of the 1 o'clock position. I used pin nails to secure the teeth on the kick starter arm and the shaft. The Electric starter just needed a little more work to sort out where it was missing insulation and shorted to the case. It really is a great bike to ride when you get it running right.
Yamaha RD models are all awesome , my first brand new bike was a 50cc RD candy apple red ,, a real rocket in your pocket bike , that power band left all the other 50cc bikes standing when we had drag races
You need to clean out the grooves on the generator armature. They are clogged with grease or dirt. Use an exacto knife. When they are plugged the starter won’t work and the generator will not charge the battery. You are in essence running a total loss electrical system. I have a fully restored 200 electric just like this one and had the same problem with it
You havereminded me how much fun renovations can be... AND, why I don't do them much at all any more! W/o the air cleaner hooked up, it could explain the lean stalling, jetting is very sensitive to air flow in or out. Good work trouble shooting tho, great videos on this bike. I had a dozen 350s, R5s, RD125s and several RZ's, so much fun to ride.
man this is the first time i have seen you give up on a bike! i would have done the same. your videos, have got me working on mine and my sons bikes! i want to thank you for all the knowledge your putting out there. you really gave me the confidence to do my own work! thanks again!

This is why joe needs a stockpile of parts bikes,thousands of these laying around, they were mass produced, just gotta buy those parts bikes up when you find em
Years ago my mate bought an RD200 as a non runner. We got it running but only on one cylinder. When the sparkplug was removed from the non-running side we laid it on the cylinder head and started it again. No spark but a bit of smoke coming from the plug! A new plug got the spark back but the crankcase on the non-running side was full of fuel/oil which took a while to clear. All ok after that. It's easy to get caught, a plug that sparks ok out of the engine might not work under compression. The electric start on his would never start it from cold. Quite a fast bike in its time.
I had one of these in 74 and rode it from Sydney NSW to Cockburn SA, a distance of 1200km in a day. My arse was so sore. I dropped it twice playing the fool. Falling off my bike or crashing it seemed to be my thing along with smoking a lot of weed. My top speed was about 92 but my buddy took it over 100mph. I finally wrote it off at 60mph when a traffic island jumped out and hit me. I was a little scraped, but every bit of the bike was bent. Tremendous fun, but the universe, my Mum and my girlfriend decided that I had been warned. In the next year 4 guys I knew died on bikes so I decided to go to cars.
Had this exact same bike when I was 14 back in 1983. I bought it from a neighbor whose grass I cut since I was 11. It was sitting in an old barn, covered in dirt. I paid $100 for it and he said it ran when he parked it there. Cleaned it all up, carbs etc, new battery and it started and ran great. The electric start went out after a year or so and I used the kick start. Broke mine same way you just did lol. I had it for years just sitting in a shed then decided to fix it up and sell it. I got $550 for it in the end and it ran great.
My friend this needs a crankshaft right hand side seal replacement. As far as i can tell the left hand side cylinder is running. I had the same problem with my rd 350 just change it and see the magic happen.
First street bike experience at 14 was a Yamaha 200 . It'll go 105 flat out laying down . Thanks for the memories and a real nice effort on your part .
Anytime an engine has been sitting that long it helps to drop some injector cleaner in the spark plug holes and let it sit overnight. The rings tend to get stuck and they don't seal well. Once they're freed up your compression will go up.
Just came across your page and its quite interesting to watch you bring these old bikes back to life. Just one thing about your riding technique, when you turn the bike around try putting the bike back into 1st gear, it makes it a lot easier to get it going.
Good on you for having a go. But you need to stop and step back and think about what you are doing. First step would be to give the bike a real good clean to remove all the dirt that will find its way into the engine if left. After cleaning the bike then the fiddling and fixing attempts can be done. Engines, especially 2 strokes and pre fuel injection, are very simple to repair. Just follow the basic troubleshooting steps starting at the beginning. The lack of 1 cylinder could very likely be down to the carby if you are getting good consistent spark. If the carby is found to be ok, then look at the inlet and exhaust. If that is ok look at all of the electrical connections then the plug, points, condenser and the coil for the cylinder. Often a faulty coil or condenser will appear to be ok until put under load. As a last resort, check both cylinders compression. If the non or miss firing cylinder is the low one, pull the cylinder and check that the piston hasn’t partially collapsed (this happened to me on an old Suzuki from the late 60s).
Get a cheapo chinese ignition switch to use. Get a starter pack too. And it never hurts to have an old car battery lying around for these 12v bikes. Love the video's. Keep up the good work.
Could be your crank seals. Love the videos! I love working on the same kinds of machines with the same issues. I’m 46 years old and love to tinker with these kind of things. Your videos are great.
Very nice video. My very 1st motorcycle was a 1971 CS Yamaha 200cc back in the early 70s. Very nostalgic. 1972 was very slightly different. Auckland. NZ
It sounds like your timing is off on the left cylinder messing with duel points is fun you can use a timing light to help and make sure you have correct point gap good luck
Even if he read your comment he won't do anything about that.. he knows how to get one started but he doesn't know technically what's really going on with either or any bike he works on to him it's just a game and his partners it's just a game to some of us we want to know all there is to know about it and why.
You timing is off, its adjusted under the cover you installed that single brush. Like everything TDC and adjust points gap for timing. Carb adjusting after timing engine, start with idle first and sync carbs. You can check each cylinder temps with air/mixture. Believe it or not these engines will scream when set up right. Its old school troubleshooting skills that get "honed" with projects like yours. BTW good job on getting it to run.
I think if you will pull the left carb off and give it a soak cleaning you will solve you missing power on that cylinder. Just fot s&giggles pull that plug and add fuel , if it runs you know the carb is the problem. Old guy logic, even you young guys need to use it. LOL. My first bike was a Yamaha YDS250 back in the mid sixties. Fun and powerful bikes for their time. 12k rpm was possible in first and 11k rpm in 2nd.
2 strokes are a world of their own. Do it by systems. If it has good spark, make sure the carbs are very clean and ready to run. Check the throttle linkage, choke, and mixture and idle settings using good 2 stroke adjustment guidelines. Find somebody who works on chainsaws and ask him for his adjustment protocol.. There is a science to it.
The sooner yall stop blowing smoke up his a$$ about being a good mechanic he may actually stop and learn something instead of just putting out misinformation vids
Dude, get an ignition switch and a wiring diagram and do it right. Ohm out the coils to make sure their good. Pull and clean the carbs. If your still having weird voltage readings check the battery in your volt meter. If you troubleshoot it one step at a time you could have it running and enjoying it.
The starter generator carbon brush has nothing to do with the ignition. The ignition on the CS5 is battery and coil which is independent of the generator.
I hope you find another one of these they had a unique sound some people would just bypass the starter/generator system and just go directly to the points another work around for the expensive brushes is get electric appliance brushes and file them to size the wireing for these bikes was a nightmare to get starter/generator working a common work around was permanent magnets around the rotor for generation only one problem with the starter system is the brushes are not big enough to really crank the bike over its a bad design but a lot of cart people used it because its a 2 stroke twin there wasnt to many twin 2 strokes made
Do not sell it and give up. Check your points gap, clean the carbs again, make sure your air/fuel is correct. And it's not uncommon for the clutch to get stuck after sitting for so long. Drain the oil and fill back up and pop the clutch in each gear. If the oil injection is working, don't run premix in it. The downside to the Yam twin 2 strokes is the bearing between the heads that control the port timing, but that doesn't sound like the issue. Sounds like carb/timing issues.
Dude, I’m telling you!!! Step outside your comfort zone, take the bike to a welding/fab shop and have 2 cr125 pipes fit to the frame. Make it a sweet mod bike. It’ll blow your mind, the performance
i learned something, stick to 1 cylinder bikes. 2 pots are twice the money to fix! , think the coil pack is junk, or the wiring has a break in it somewhere
Dude I was wondering when you were going to post another video, sucks you couldn’t get it running but it made me laugh when you said you were tired of looking at it lol
Hi.....I seem to have an electric issue with a piaggio MP3 urban trike scooter, I leave it out in the damp weather here in the UK, the battery is at 133 which is fine, but the other day the starter motor wound'nt work then the brake light I manged to fix both issues, but I have no choice but to leave it outside.

Boring a hole thru' kick start axle and putting a bolt in it doesn't work - I have tried it also with my Yamaha 125cc 1974. Due the metal stress the bolt breaks making the axle not function properly anymore loosing its grooves. So I had to go back to eBay and order again order the second NOS axle instead. (the problem was in improper kick start lever that didn't fit after thorough inspection - the number of grooves didn't fit together). Whe I received a new axle and proper lever things started to function properly. Although I haven't time enough to see if I can start her due gas (leaking petcock inspite of new seal) and electric problems. It takes sometime a couple of months to do something else than repairing a cycle that doesn't work. It's frustrating.

Years ago my mate bought an RD200 as a non runner. We got it running but only on one cylinder.

A new plug got the spark back but the crankcase on the non-running side was full of fuel/oil which took a while to clear. All ok after that. It's easy to get caught, a plug that sparks ok out of the engine might not work under compression. The electric start on his would never start it from cold. Quite a fast bike in its time.
I had one of these in 74 and rode it from Sydney NSW to Cockburn SA, a distance of 1200km in a day. My arse was so sore. I dropped it twice playing the fool. Falling off my bike or crashing it seemed to be my thing along with smoking a lot of weed. My top speed was about 92 but my buddy took it over 100mph. I finally wrote it off at 60mph when a traffic island jumped out and hit me. I was a little scraped, but every bit of the bike was bent. Tremendous fun, but the universe, my Mum and my girlfriend decided that I had been warned. In the next year 4 guys I knew died on bikes so I decided to go to cars.
Man you have come a long long way since this video.
Good for you
At 19:14 I just burst out laughing looking at that franken bike. lol Great little project thought!
Happy Friday keep up the good work love the videos
Had this exact same bike when I was 14 back in 1983. I bought it from a neighbor whose grass I cut since I was 11. It was sitting in an old barn, covered in dirt. I paid $100 for it and he said it ran when he parked it there.
Cleaned it all up, carbs etc, new battery and it started and ran great. The electric start went out after a year or so and I used the kick start. Broke mine same way you just did lol.
I had it for years just sitting in a shed then decided to fix it up and sell it. I got $550 for it in the end and it ran great.
You are doing fine. Learning how to be a mechanic doesn't happen overnight. Just keep learning and pushing on.
Joe you know when to walk away. Right on brother
My friend this needs a crankshaft right hand side seal replacement. As far as i can tell the left hand side cylinder is running. I had the same problem with my rd 350 just change it and see the magic happen.
First street bike experience at 14 was a Yamaha 200 . It'll go 105 flat out laying down . Thanks for the memories and a real nice effort on your part .
Anytime an engine has been sitting that long it helps to drop some injector cleaner in the spark plug holes and let it sit overnight. The rings tend to get stuck and they don't seal well. Once they're freed up your compression will go up.
Just came across your page and its quite interesting to watch you bring these old bikes back to life. Just one thing about your riding technique, when you turn the bike around try putting the bike back into 1st gear, it makes it a lot easier to get it going.
Good on you for having a go. But you need to stop and step back and think about what you are doing. First step would be to give the bike a real good clean to remove all the dirt that will find its way into the engine if left. After cleaning the bike then the fiddling and fixing attempts can be done. Engines, especially 2 strokes and pre fuel injection, are very simple to repair. Just follow the basic troubleshooting steps starting at the beginning. The lack of 1 cylinder could very likely be down to the carby if you are getting good consistent spark. If the carby is found to be ok, then look at the inlet and exhaust. If that is ok look at all of the electrical connections then the plug, points, condenser and the coil for the cylinder. Often a faulty coil or condenser will appear to be ok until put under load. As a last resort, check both cylinders compression. If the non or miss firing cylinder is the low one, pull the cylinder and check that the piston hasn’t partially collapsed (this happened to me on an old Suzuki from the late 60s).
Get a cheapo chinese ignition switch to use. Get a starter pack too. And it never hurts to have an old car battery lying around for these 12v bikes. Love the video's. Keep up the good work.
Have a 12V 'jumper' of some sort for cold starting at home. The battery was only good for warm starts.
Could be your crank seals. Love the videos! I love working on the same kinds of machines with the same issues. I’m 46 years old and love to tinker with these kind of things. Your videos are great.
Don't give up, 2 cylinders is a new challenge and a chance to learn. Don't give up.
Very nice video. My very 1st motorcycle was a 1971 CS Yamaha 200cc back in the early 70s. Very nostalgic. 1972 was very slightly different.
Auckland. NZ
Ihad a RD 350 yamaha back in the 70's , very fun bike!
Those Nick's and dents you are talking about came from impact with something!
It sounds like your timing is off on the left cylinder messing with duel points is fun you can use a timing light to help and make sure you have correct point gap good luck
Points on these twinsneed to be set up with a dial indicator on both Pistons that's why the points have the screw settings because it is so critical
Even if he read your comment he won't do anything about that.. he knows how to get one started but he doesn't know technically what's really going on with either or any bike he works on to him it's just a game and his partners it's just a game to some of us we want to know all there is to know about it and why.
Sometimes ya gotta throw in the towel. Smartest choice with this bike IMO
It was nice from ur part….good learning experience…thanks 🙏
You timing is off, its adjusted under the cover you installed that single brush. Like everything TDC and adjust points gap for timing. Carb adjusting after timing engine, start with idle first and sync carbs. You can check each cylinder temps with air/mixture. Believe it or not these engines will scream when set up right. Its old school troubleshooting skills that get "honed" with projects like yours. BTW good job on getting it to run.
The bike was layed on its right side for storage. Thus your carb situation. Stuck slider etc. Cool old bikes. I had an rd 400 back in the "80s "
I think if you will pull the left carb off and give it a soak cleaning you will solve you missing power on that cylinder. Just fot s&giggles pull that plug and add fuel , if it runs you know the carb is the problem. Old guy logic, even you young guys need to use it. LOL. My first bike was a Yamaha YDS250 back in the mid sixties. Fun and powerful bikes for their time. 12k rpm was possible in first and 11k rpm in 2nd.
You can use windex to clean the electrical connections and it will make them look new.
Looks like a change of scenery . I haven’t been watching for a while
Get a airbox on it and why it isn’t run on one cylinder is it be weak spark that will sparking on side of plug instead of middle
That's called the brush Bubba Louie, that is the spring that pushes the brush against the commutator.. the starter is basically an electric motor
2 strokes are a world of their own. Do it by systems. If it has good spark, make sure the carbs are very clean and ready to run. Check the throttle linkage, choke, and mixture and idle settings using good 2 stroke adjustment guidelines. Find somebody who works on chainsaws and ask him for his adjustment protocol.. There is a science to it.
dont give up on it!!! wanna see it running like it did when it came off the line
Awesome video man
Definitely one of my favorite channels i wish you had more videos lol.
Don’t let it beat you your a gd mechanic I’ve watched loads of your videos keep at it
The sooner yall stop blowing smoke up his a$$ about being a good mechanic he may actually stop and learn something instead of just putting out misinformation vids
Sweet video. Love older bikes
We love you bro, but we all been there when you just have to say thats IT! Roll it out to the trash.
I like the new garage!
looks like you need a big pair of vise-grips with a slide hammer welded to it. for those stubborn motor mount bolts.
Dude, get an ignition switch and a wiring diagram and do it right. Ohm out the coils to make sure their good. Pull and clean the carbs. If your still having weird voltage readings check the battery in your volt meter. If you troubleshoot it one step at a time you could have it running and enjoying it.
Love your videos. You should do electrolysis on tank rust. Lots of videos on it and easy as pie.
26:46 now that's how you tune a alternate firing twin hold down on the starter maybe it'll get you home
Great video and I feel your pain when thing aren't going well
Keep up the great work never give in
Keep doing your thing Joe. Where all watching the hard work n great vids you post up . 👍🏻💪🏻
Last month I bought a 1972 Yamaha RT2 360
I restored a 71 RT1 360... make sure the points are in times or else your ankle will be destroyed.
Ok
Awesome build series brotendo
Great vid. I learned a lot!
I love these 200cc Yamaha twins I build pipes for them to make big power, mine does over 100mph now
Post a video of that. I have on of these as well and would love to see an example capable of 160km/h.
I’m sure the og pipes on this need to be cleaned out.
The starter generator carbon brush has nothing to do with the ignition. The ignition on the CS5 is battery and coil which is independent of the generator.
I hope you find another one of these they had a unique sound some people would just bypass the starter/generator system and just go directly to the points another work around for the expensive brushes is get electric appliance brushes and file them to size
the wireing for these bikes was a nightmare to get starter/generator working
a common work around was permanent magnets around the rotor for generation only one problem with the starter system is the brushes are not big enough to really crank the bike over its a bad design but a lot of cart people used it because its a 2 stroke twin there wasnt to many twin 2 strokes made
Do not sell it and give up. Check your points gap, clean the carbs again, make sure your air/fuel is correct. And it's not uncommon for the clutch to get stuck after sitting for so long. Drain the oil and fill back up and pop the clutch in each gear. If the oil injection is working, don't run premix in it. The downside to the Yam twin 2 strokes is the bearing between the heads that control the port timing, but that doesn't sound like the issue. Sounds like carb/timing issues.
Dude, I’m telling you!!! Step outside your comfort zone, take the bike to a welding/fab shop and have 2 cr125 pipes fit to the frame. Make it a sweet mod bike. It’ll blow your mind, the performance
I have a 81 but it's Honda cm200 it's great
i learned something, stick to 1 cylinder bikes. 2 pots are twice the money to fix! , think the coil pack is junk, or the wiring has a break in it somewhere
You've come a long way since this video. 9/13/24
I had 2 of those in the summer of '85, '72 Yamaha RD 200 electric. It had low mileage, it was fast
Awesome footage /AWESOME CHANNEL 😎🙋👍
Hey @2vintage you should build up a 300ex
- une belle machine, merci pour la video !
Dude I was wondering when you were going to post another video, sucks you couldn’t get it running but it made me laugh when you said you were tired of looking at it lol
Hi.....I seem to have an electric issue with a piaggio MP3 urban trike scooter, I leave it out in the damp weather here in the UK, the battery is at 133 which is fine, but the other day the starter motor wound'nt work then the brake light I manged to fix both issues, but I have no choice but to leave it outside.
Huge fan here too like your vids keep them going buds👍👍👍
I really like your efforts on this bike. Hope you can find an original gas tank replacement the plastic tank is ugly as homemade sin.
The rat bike joe 😂 you have the patients of a saint mate
For corrosion on wire connections try using penetrox or noalox found at any electrical supply house
You should look for a Honda xr70 or crf70 they are great little bikes
I own a 70
Im looking so i can go plant some lovely smelling plants somewhere quiet as they run silent lol and there worth 750 1000 pound here in great Britain wa u ride bro i ride honda crf250r check my beast on my channel bro safe
Ok
Boring a hole thru' kick start axle and putting a bolt in it doesn't work - I have tried it also with my Yamaha 125cc 1974. Due the metal stress the bolt breaks making the axle not function properly anymore loosing its grooves. So I had to go back to eBay and order again order the second NOS axle instead. (the problem was in improper kick start lever that didn't fit after thorough inspection - the number of grooves didn't fit together). Whe I received a new axle and proper lever things started to function properly. Although I haven't time enough to see if I can start her due gas (leaking petcock inspite of new seal) and electric problems. It takes sometime a couple of months to do something else than repairing a cycle that doesn't work. It's frustrating.
I’m sure you won’t message back from this but Wholly Crap man your a mechanical Genius
My father lived his life a Mechanical Genius to good for you bud these videos sure bro g back memories of my old bikes I had 👊😊
Battery that i bought i have to put trickle charge throu the winter or it will be junk. Its been like this for years now. Thanks for this
