  1. JE's response as follows. will shim the plug. Victor, Either use the surface discharge sparkplug or shim the plug with an additional spark plug washer to keep the piston from contacting the head at higher RPM's.

The bike had roughly 10 Hrs on it all bearings in bottom end were good I got every thing back together bike idles good but under hard acceleration the piston is nicking the spark plug and closing the gap to about .10 inch I re gap to .30 inch and it dose it again I look down the plug hole in the head and can see where it is hitting the piston and I would like to talk to some one about this and get some clearance information.

Check this out i looked on JE's catalog and they refrance their own gasket kit in stead of oem check it out www.jepistons.com/pdf/2006-moto3.pdf check it out on a hi comp piston for say a KX450F the gasket in OEM but for the KX25F hi comp it jists their gasket number ??? if this is the case it would have been nice for the to tell me in the instruction or some where.

  8. I know i have a 250F but i need some help from any one on this quick Hey guys Check this out my JE 13.5:1 piston is actually tapping the plug and closing the gap to about .10 Inch only under hard acceleration. i regaped the plug and kicked the bike over sevral times and i didnt touch it. i can shine a light in the spark plug hole and see where it is hitting it what the hell is this all about. cosmtic gaskets like oem style and oem plug

  11. wasnt a jetting issue at all. I took the carb all apart today to clean it pu the FMF jetting back in because it actualy ran with them in the first place. put it all back on and still ran like crap. Pulled the plug and the gap was crushed to almost nothing regaped and it ran great. i did notice that it started to get a lilte rough when i was riding it and now i will check the plug to see how it is burning rich or lean and adjust from there. I will keep you posted and see how every thing goes. als the oil issue is from my waterpump cover, it was just blowing up on the crank case and made it appear as it was leaking from the cylinder. Thank you Eddie for all your help thus far.
  12. I did use stock needle 3 clip from the top
  13. Also I was leaking oil, thought it was from the water pum cover oring but i looked today and it looks as it is comming from the cyilnder gasket. i tourqued the head down to spec and installed a all new gaskets maybe i will have to take it all apart agian or what.
  14. I picked up up a 180 OEM main and installed the 42 pilot Bike will star wit the choke out, will not idle at all with the choke in and will die as soon as i open the throttle., it just bogs out.
  15. I have a kx250F 2004 and just rebuilt the bike and run FMF jets and have the same problem. I am switch back to stock jets today and will stick with the oem jets or JD jets.
