The bike is a 2003 450f
Full DRD exhaust
Boyesen quick shot
Stock everything else engine wise
It won't kick start to save its life, and will only start with a jump. It revs and idles ok, but when I try to ride it it has a bad hesitation even on constant throttle. Kind of jerky and pops a bit. I checked timing, replaced the plug, cleaned the carb, new fuel/oil for good measure.
I checked the valves and the clearances on the intake side are very tight, but in my experience its usually a bad sign if they are loose and not too tight.
Any pointers on where to go from here? Im going to try replacing the pilot jet in the carb so see if its clogged or something. I don't want to pull the head if I don't have to but would like to ckeck for bent valves just in case.
