Re: Sprocket clearance
So long as the chain runs straight and true between the engine sprocket and wheel sprocket, do whatever you have to do. A "slight twist towards the bike in a section" does not sound too good to me.
It should not kill you if the chain flys off while you are going 1 MPH. Any faster and all bets are off.
Follow Cogswelln's lead as well.
