Re: clutch starts to engage while lever is fully pulled in after a long ride?
I have the gear ratio program (available somewhere on this forum). I put in a 60 tooth rear, everything else standard, for a 26" wheel.
You would have a drive ratio of 24.6 to 1 (man that's low)
@ 7000 RPM you're speed would be 22 mph.
I dunno about pullin a wheelie, but I guess it might.
