Hello everyone,

I am new to the site but have been on it looking around for awhile, so I thought I would join. I have a small question that I need a little help with. I have looked over some threads on my issue and it seems to be a trial and error thing but I hope you guys can get me real close and save me some money.
I recently bought a 2006 KFX 700 and the boy had put a Whites Brother full exhaust on it but never re-jetted it. When I got it, it had good power at mid-range but cut in and out at top end. It also had a lean pop or sneeze at idle.
It had the factory jets in it but I changed them today with a 140F and 145R with 42 Pilot Jets. The lean pop at idle is gone but it still cuts out at WOT. It only runs 50 mph ( GPS ) . Can you guys get me closer and save me some money. Thanks in advance guys.

 

Just to kinda clear up what it is doing at WOT, it feels like it is hitting the rev limiter. I know it cannot being doing this at 50 mph. Thanks

 

Thanks for all the help......................

 

Welcome to the forums! I can't help answer your question, but do suggest you check out the forums at kawieriders.com. There are a lot of VForce riders over there with a ton of tuning knowledge and I would imagine you will find an answer to your question there very quickly. Hope this helps. Thanks.
