why doesnt this site have a censor anymore?
eff this and eff that...
if you know what size the shaft is... try ebay, for 1/2" pitch sprockets. industrial. few different sizes, lets you play with ratios...
is the chain in a straight line? have you tried seeing if anything can be simply shifted over a touch?
its a fat wheel...pretty sure mine has only a 1/4" clearance with the normal chain anyways...
is it rubbing? flinging off? if not...whats the problem?
