Question about 2003 Yamaha WR 450 F
I have hesitation problem off idle. The bike spits and sputters from 0 -1/4 throttle opening. Wide open runs great. I've adjusted the fuel/air mixture screw with no real results. screwed all the way in will not shut the bike down. I'm lost, please help
Sounds like a jetting issue. change the main jets starting from the largest one you own and work your way down.
