the fillet on the aussie crank is smaller than the US crank, case in point after test fitting the JP on erics crank i can slip an .008 shim behind the sprocket....there is almost no chambfer on the JP crank gear...

no problem i'll just chuck it in my leblond

btw fer those of ya who run dbl's if i had a relatively cheap (and completly reversible) way to block the rear balance shaft bearing oil holes, how many of you would ditch the weight of the balance shaft? or would you still just pull the gear and leave it in with the 3 thou clearance blocking em?
