  2. Hello everybody! I would assume it's not often people come here and ask about Yamaha TZR50 issues. I'm brand new to bikes, this is my first moped I am learning, and I've owned it for about a year now. It has some issues that I want to look into. It has a prebought CDI tune, and I think this CDI has caused some issues for the bike (can't be sure though, I don't have the OEM CDI). The issue is at midrange RPM, the bike struggles getting up in speed, even on flat grounds, it doesn't gain any speed at all and just remains on the same RPM and sputters like it's getting too much or too little fuel. Possibly running too rich? (I have to shift down to get up in speed) How would I check on this, and do someone here have any tips and tricks I could use to check it out? I have tinkered a bit with it, pulled off every piece of the bike and engine that I feel comfortable with (max the carb). So I have tried to learn, but I couldn't figure out why it sputters. I also believe it's getting too much oil, it eats oil like crazy, compared to my other moped. Can this be adjusted too? I can't test drive it sadly, because the chain is too loose and it jumped off during driving one time. You guys here probably have a lot more experience than me, and asking you would probably be the best choice here. Best regards,

  5. I'd give it a go. make sure it mics out with thicknesses and lengths etc. nothing to lose really
  6. So this is a 1999 R1? There's a big ass fuse on either side of the starter assay. Try those first.
  7. You need a circuit diagram to trace the circuit. Have you tried the R1 Community? They have a circuit diagram here. https://www.r1-forum.com/threads/annotated-wiring-diagram.642907/ I'd consider joining them also, somebody there might help shed some light on it as it may be a common problem with your bike.
  8. Iwe been playing with my multi meter and traced where I have V and where not. So doesn't get to starter relay, ignitor box, start switch or headlights but dash has some V without showing signs of life. Just to add, I had dash and crank but once I trailer't it home I connected battery with jumper leeds hear a click and nothing, dead. I thought I did a fuse but that doesn't seem to be the case
  9. I recently got a 2009 Yamaha FZ6R. It's missing a starter Idler, which I finally found whilst taking the bike apart trying to diagnose why it wouldn't start. I have access to parts from a 2006 R6. So my question is, are the parts Compatible? The part numbers, are all the same except for the first 2 digits, but both parts look identical from a image perspective. Does anyone know if these bikes are compatible though? The 2009 Idler part number is 20S-15512-00, but the R6 part number I want to see if it will fit is 2C0-15512-00... Is there a big difference between 20S and 2C0??? Or will it work? I'm on a budget so if I am able to use the 2C0 on my FZ6R I will be happy saving a buck and a half at least on this. The bike was a fixer upper. And thats one of the last thing needed to get it going.
  10. hi @Snakebite68, i'd love to get a copy of the manual as well to do some modifications my my XSR 125, i can't send you a message unfortunately as i've just registered my account, do you mind dropped me a message and i'll share my email! many thanks
  11. Aaah, yeah, that will do it lol. Should be an easy job... Your best bet for a refurb kit would be a Yamaha dealer, and just do it yourself. If you have the original hydraulic lines, there's also a possibility that it has deteriorated and collapsed inside, but that's fairly unusual. Of course, it's also possible the master cylinder has failed...
  12. hi there is no air in the system ,i now find that the rear piston is siezed i think ,even with new pads the foot pedal works but little or no affect ,i think caliper needs a rebuild
  13. Earlier
  14. Congratulations! Well, the main thing is that you have fun riding it..
  15. So the next day I rode it to our local moto enthusiast hang out here in Tucson, Gear Shifters, and the owner immediately invited me to submit it for curation in the 520 Moto Show presented by Iron Horse Motorcycles (shameless plug). I didn't have to think about that too long. It now has a little over 200 miles on it! I think the fueling is not quite right though. The pilot jets are for Portland elevation around 400 ft. give or take and i'm now at over 2200 ft. Or maybe the fuel pump is gunky or maybe the fuel filter is gunky. In any case, I still have some fueling issues to work out. Other than that, I feel a rock star riding it! I finally found a downloadable service manual that covers the 1995 with the KYB USD fork and figured out how to free the spring from the damper rod. Of course it requires a special tool that can easily be improvised with some plastic pipe and a washer but since the seals can easily be replaced without disturbing the spring, I decided to simply wash everything with Maxxis Suspension cleaner and call it good. Rather than using air space to measure oil, I used volume. I put in slightly more than 16 US ounces in an effort to stiffen the compression a bit. I also used 15W oil. I won't bore you with all the work, time and money I put into this project but it was a fight at every turn. Now the bike that had been "stored" for 29 years with 162 miles on the odometer, now has 168 miles on it. Tomorrow, much more! https://www.facebook.com/bicycle.repairman.75/
  16. Now I've read this model is Indian and not chi ese as t guy from service told... Pb don't even need to change t engine just to open it and buy t necessary part... No is not a yamaha deal just a simple garage with an old guy...
  17. Nice one Danny, Glad you got it sorted, now you can clock those miles up. As a reward , here on the site we have a badge system, the more votes you get, progresses you up the ranking, it's only for fun! nothing elitist or special about it!! You can even get on the leaderboard for post of the week, gold silver and bronze On the bottom right of a post there is a grey heart (gray as you're in the US) you simply click on it to give someone a thanks etc, these likes put you on the leaderboard on the top right, the more you get contibutes to your profile. so I'm going to start the ball rolling and like your posts etc. and you'll see your name on the leaderboard!! All the best NE0

    I'm sure there's a chart somewhere online that states the equivalent aspect ratio.

    Scrambler

    Hello, I've started working on a scrambler project, using a xj600. https://yourimageshare.com/ib/OxSQ6TcdyQ https://yourimageshare.com/ib/2w25wi8qqg But I have hit somewhat of a problem. My tyres are 110-80-17 and 130-70-18 and I can't find off road tyres with those sizes. I was thinking of using 120-90-17(not tubless) and 130-80-18(tubeless) instead. Would this work? Any thoughts? Thank you.
  21. I can lock it if you want NEO, but, maybe we need a 'How To' section and you could transcribe the important bits there?
  22. Unbelievable!! I've just been looking at the stats and this post has now surpassed 135K views making it the most viewed topic in the Workshop Section of this website. Hopefully, its been of some use to you all 6 to 12volt converters. I started this post back in 2011, and here in 2024 its still going strong on my DT175MX. In the next few months I'm going to ask the mods to lock the topic, as I don't think there's any more to add from my point of view as all the information for a successful conversion is contained herein,and little has been added in the past few years. In future If anyone is having trouble with their own conversion it would be sensible to start a new thread for their bike and reference my post within the subject and where you might be having the trouble. Keep on tinkering! NE0.
  23. ...and a warm welcome from me too.
  24. check wheel bearings too can transmit through the drive chain
  25. try the earth first. clean the area. undo the block connectors and spray with contact cleaner and a bit of acf or equivalent
  26. Welcome in. We aim to try... lol
  27. Hi all, hoping someone can point me in the right direction, Bike has new battery and fuses are OK, getting 12v after fuses but no lights or dash or relay click. I'm a bit stuck on where to go next, is there a way of testing relays? Is bad starter relay going to give these simptoms? Any advice is welcomed
