woodro77 Posted January 25, 2006 Report Posted January 25, 2006 (edited) the difference would be the piston smashing the head,it wouldnt fit Edited January 25, 2006 by woodro77 Quote
iceman Posted January 25, 2006 Report Posted January 25, 2006 yeah unless he put a bigger cylinder on it. it wouldnt fit. Quote
slowpokebanshee Posted January 25, 2006 Report Posted January 25, 2006 if the crank has a 5mm longer stroke, than you would need a 5mm spacer plate to make it work. Quote
seb4lo Posted January 26, 2006 Report Posted January 26, 2006 if the crank has a 5mm longer stroke, than you would need a 5mm spacer plate to make it work. 464386[/snapback] a 2.5 mm spacer is enought Quote
