  1. I have one but for stuff like jets and electrics it says take it to s yamaha dealer
  2. How do you test the stator
  3. It runs great every where else but one at about 9-10k rpm it sound like it runs out of gas then cuts back on then of and so on and so forth
  4. I never really rode hard until I got the pipe. Like I wasn’t very good got the pipe then later progressed to be able to ride better. I will try putting the stock pipe on but I couldn’t really think how the pipe would be the case because changing jets should effect it
  5. So my 2009 yz85 will chick if at about 9-10k rpm. I know it might not be good to run that high but at a face of a jump it’s sometimes necessary. I also have a pc platinum pipe.This is all we’ve done. Jets: 138 main(stock), 135 main(pc recommend),clip 3 (stock),clip2,clip4 Float: float was low 17.5mm (stock-18-20) Moved it up to 19 but no change. Spark plug: yamaha says to run a br10es but I run a br9es I think it may be the stator but Idk.
  6. Sounds like the ktm 300 and 250 xcw tpi vs carb. The tpi was smoother mid range but was jerky and not smooth down low, as the carb with good jets was smooth down low and all the way through top, injection hasn’t been around in dirt bikes that long but trust me give it time and it will replace carbs on all bikes. Just like cars fuel injection replaced carbed cars
  7. I think it’s from 2018 I looked at a few 2018 dyno results and they where all right about the same. I also saw a costume build Honda 250 vs stock 250s and it took the lead in mid and top but was last down low, 250s they rev real high anyways and if you are okay with shifting more and reving higher that might not be a bad way to go
  8. That was informational but I’ve always wondered why a unicam design. Why unicam over DOHC doesn’t the double can respond better at higher RPM. And if the 450s don’t have the power problem just because they are 450s wouldn’t that mean that the crf450s could have even more power than it does now, because it’s the same engine design?
  9. The only reason I see for twin exhausts is less back pressure but a less restrictive single will do it to. Plus aren’t motorcycle exhausts short enough anyways that the pressure difference wouldn’t be noticeable
  10. I could not tell you if that worn edge would be enough to cause problems but I know if a snap ring is missing in between two gears it can cause the gear to slide a little between the higher and lower gear. This can cause a false neutral. It’s a long shot but happens to my brothers 65
  11. Get it fixed?
  12. I started thinking it may be the float because the stock jets fouled plugs in the beginning but it ran good, now stock jets do the same problem. I’ve been in the carb a lot in the past few weeks so may have bent the float. That’s what I’m thinking
  13. I never checked the float, I ruled it out because this problem came with the new pipe. I will check Those are the Jett’s I bought
  14. So I have an after market pc platinum pipe. For a while ride with stock Jett’s but then I switched to the leaner pilot main and clip position. But I’ve tried every jet setting I could with stock and leaner Jett’s and the bike wants to choke off when WOT and when reving in neutral it doesn’t want to rev out and sounds like a 4 stroke rev limiter. There’s just no over rev I think it’s also worth mentioning that I’m running a ngk br9es when the book calls for br10es. The 10s foul with stock Jetts
