I just picked up an 04 450r yesterday it has a sparks head and cam. It also has a +3mm crank, 13.5:1 piston full yosh exhaust no airbox lid and crf flywheel and wiring harness. The motor was just built and only has had about 2 tanks of fuel through it.
I took it out today and it works awsome except when i hold it to the bar it seems to cut out and almost die untill i let off then works fine. I am assuming that it is the main jet not being large enough and it is starving for fuel when wide open do you guys agree or do you have any other imput?
