View Full Version : KFX won't run.........

Removed the oil injector, dropped down to an 87.8 MJ, and the little pile O'smell falls on is tail? I installed a 90 MJ, same result:(

Any clear headed thoughts?

Maybe a better explaination of "falls on it's tail".
You mean the rider??? LOL

unfortunaly it wasn't rider error, 2/3 thru the straights the bike would run out of power. I watched his foot, he wasn't even close to the brake pedal.

Now I have a hot 6 year old! He wants to unload the machine (that is only 3 months old). He thought about it a bit more and asked me to bolt the injector back on.

what are the possibilities that 40:1 is too lean, and the rings are not sealing good at 2/3 straight away. Should I try going to 32:1 and test that theroy?

It'll run the same with or w/o the injection.
I do recommend 32:1 but feel that isn't the problem.
Is it spitting and sputtering on top end?
Still do it w/ 92.5 main jet?

Yes, sputtering on top. I haven't put the 92.5 back in it yet.

I did block up the rear end, bring it to WOT and pull the choke, it sputtered reall bad. That is why I was thinking going heavier on the mix ratio.

I drained the 40:1 and replaced it with 32:1. It will continue to pull lap after lap. Here he is testing his Works Shocks today. It runs a whole lot better :D
