Has anyone had any problems with their AIM clutch kit not letting you shift? I put a 107 kit in and installed the AIM kit. Since then, my shifter is noticeably harder to pull up when riding somewhat aggressively. When I really give it the juice and try to shift at high RPM it won't shift at all. It almost seems as the clutch never disengages when I pull the lever! I've tried letting the RPM's drop when shifting but it seems I lose so many RPM that its not worth having. My adjustment is spot on according to the installation instructions...anybody else have this issue?
