I have a 08 yfz450 that i recently bought. It ran good and such for a day. but this week when i ride it it dies when i pull in the clutch. Like i will be pinned and come to take a corner and pull in the clutch and it dies sometimes. It idles just fine. I have the air/fuel two turns out and i have the spark arrestor out of the pipe. I am sea level. I also just put in a 168 main jet hopping that would fix the problem.It didnt. what do i need to do!?

 

You said coming into a corner is it while braking hard?
