Hey all, running into an issue with valve float. This is on a Hemi Predator 212cc. Specs are as follows....
Head is stock other than .050" shaved and 26Lb springs
+.020 billet rod
ARC speedway billet flywheel.
26mm chikuni carb
.010 head gasket
CM Grind cam
Bike is a doodlebug with geared at 5:1
Issue comes in that it seems to hit valve float at 6600 RPM free revving I think i am going to drop to a 6:1 to gain a little more acceleration off the line but with the engine shorting me 1000 RPM from what is expected I am hesitant as I'm kind of a speed freak....
Guess its an open ended question... I haven't played with jetting yet as the plug has had a clean electrode with a sooty exterior so I'm leaning that it is jetted fairly close. Lash is set at .003 on both intake and exhaust.
