Just picked up an 06 the other day. Knew it was lean as soon as i rode it. Pops on deaccel and cuts out if you stab the throttle down low. Had a 40/180 pilot main in it. Bought a 42 and didnt notice much of a change. DO i need to go to a 45? runs really good up top just off idel it sucks. But it does idle fine also.
