  1. Check this out. http://www.emperorracing.com/small company in Canada's west coast . Very tough stuff !
  2. Hey I have a 90py 90cc xrage dirt bike my son is learning on. The rings are now shot its burning more oil than fuel haha. I am looking at a 110cc cyl kit for it. I know the 90cc and 110 cc motors have the same stroke so fitting the 110cc jug should not pose a problem. I just want to make sure that the cylinder head will still work. Anyone know ?
  3. Have you checked for spark and fuel ?
  4. The crank seal behind the clutch might be leaking tranny oil into the crankcase.
  5. The only thing I can think being an issue if everything else looks normal would be blown out crank seals. Whay did the old spark plug look like. Was it coverd in oil. Does the tranny oil smell of gas ? Is there oil leaking out of the stator side of the motor ?
  6. Cheers I just want to try it to see the difference then ill get to the fine tune it.
  7. Hey ive read the timing thread. I just need to know on my 1989 yz250 which way do I turn the stator to retard the timing toward the front wheel or the rear ?
  8. Ok here we go, I have 1989 yz250 wr it has Fmf fatty, turbine core, boyseen power reeds, 9 oz flywheel weight, I'm running 13/52 gearing. So I had the gearing set up when I had stock pipe, reeds. I had to replace the pipe after I crushed the stocker, it was the only one available as were the reeds afterI discovered the old ones chipped. Now the power delivery is great in the wide open but as I get into the Nasty steep rocky root infested trails here in the Pacific west coast of Canada its like trying to ride a cheetah thats on fire. Any idea if higher gearing would help with this or is there a way to slow it down a bit tame the power. I have heard reed spacers, retarding timing, and other things help but I'm not sure if any of these work. Item #2 idle. I have jetted this bike so it works perfectly where I ride. It is very responsive at all throttle openings. I just cant get it to idle when it warms up which is a bit of a pain when going down hill clutch in and it stalls. Any ideas ?

  10. IYa know, the shop that I buy my stuff from only showed a 40 and 45, I never thought there was a middle jet, so I check the google and see that mikuni makes a 42.5 for the carb. Its on order now, Ill update the thread when I get a chance to test. Cheers Thanks peaceofwork
  11. Good thought, I checked, the throttle cable has slack and the slide sits all the way closed. the issue is with the 40 jet it idle's to high with the air screw all the way closed but the throttle response is noce and crisp. With he 45 it won't idle until I have the air screw out 5 to 6 turns and then its idleing, just. The throttle response is boggy. Im gonna rip the carb down again soak it in some cleaner and give all the circuts a good dose of compressed air put the 45 back in and see what happens. In the meantime any thoughts would be great.
  12. Yes, I have the idle screw out. I have checked float height, Pilot jetting is crisp with the 40 and screw all the way in idle is still to high. I put the 45 in and it wont idle unless the air screw is almost all the way out. and then its just. the throttle response is boggy.
  13. Hello I have a 1989 yz250wr i just added an FMF fatty pipe and turbine core scilencer. Ive rejetted the bike as per FMF guide lines. I found the pilot jet to be to rich #45 so i went down to a # 40 . with the 40 jet in I have to have the a/f screw fully closed and i still have a high idle with the 45 in i have to have the a/f almost all the way out to get a low almost dieing idle. I am perplexed the compression is good as are the crank seals. I'm in an area thas is at sea level and trails are up to 2000 m. all testing was done at 100m above. Its is the pacific northwest type of weather so it is moist but temps are 10-25 deg C. Any thoughts ? Cheers
  14. Hey everyone So heres the story, I have an 1989 Yz250wr that I ride woods only it has stock everything. The pipe has been welded back together more times than I can count. I mashed it on a very pointy rock on the weekend and well its done. The only pipe I have available to me is an FMF Fatty or a not so nice looking stocker. I also have a turbine core muffler on the way. So the question is how will the pipe effect the bottom end on the bike as I do most of my riding in 1st and 2nd gear in tight trails ? Thanks for the opinions cheers
