Hey,did a valve adjustment on sons 70f yesterday,and they still got a lot of chatter, i set them at .005 as per manuel.can i go to .003 or will i messs them up,or is the chatter normal on a 70f

Go .002 on the intake and .003 on the ex. That's what i set my CRF 50 to and its bored and stroked to a 108, works awesome w/ no problems!
