Hello, I'm having an issue with my CT70 and I can't seem to figure out what's going on. The bike shifts totally fine when it's not running. I can manually spin the fly wheel by hand and shift between all gears fine. However when the bike is running, as soon as as I touch the shift lever, I just hear grinding and it won't do anything. Does anyone have any insight? I've taken apart the clutch cover and everything appears to be in place for the mechanism to disengage the clutch when you shift. Thanks!
