I run a gpz750 cam, is there anyone who makes an adjustable sprocket for these or only on aftermarket cams? I'm having a little flutter problem at idle. it runs fine but I can definitely feel it pushing out of the carbs, it completely clears up at about 2500rpms, from what I understand this could be shim height or cam timing, my shims are all set for .008-.012" is this to tight? or is it the timing.
