Hey Everyone, So I recently bought a dyno jetting kit for my 01 YZ426F. The power isn't bad but I know it's not the most it could be. I'm currently running a 42 pilot, 170 main, and dyno needle on the 3rd clip from the top. I live in Phoenix, AZ and the elevation is around 1100 ft w/ a temp of 70-110 degrees. I have so bogging issues when I quickly get on the throttle (that first 1/8 or so) which I've heard the BK mod will fix. Does anyone think changing the needle position to maybe the 4th clip from the top will give me a little more power from 1/4 to 1/2 throttle? Also, I'm running a DR D full exhaust w/ an aftermarket air filter.. Thanks!
