Im having trouble with my 2001 WR 426. The chain is slapping continuously. When i accelerate hard from the bottom end up, or if im trying to cruz at a steady speed, the chain seems to slap at about 2 times a second.

The tightness is to specs, i have checked it over.

Also i am running lid off, vortip and i am at sea level. I am experiencing a random temporary studder at 1/4 to half throttle. I am still running stock jets. Does anyone know a perfect combination to smooth this problem out?

Thanks so much.

Chain noise = normal WR/YZ thing..
Jets = raise your needle one notch, or go up one on your pilot jet to a #48
