Ok, I got my Pit Bull rear foward stand in and decided I'd clean the chain again and thought I'd check the play in the chain. Can the chain play be measure while on the rear stand? How do I measure it and where do I measure it from? I know the bike is supposed to have 3/4 of a inch of free play. Well crap, just remembered all the crap has to be torqued to a certain weight and I don't have a torque wrench.
