Needing info on a 60mm crankshaft
I would like to get a stroker crank for my 155cc but it says my crankcase will need to be machined for it to fit. I measured my stock crankshaft looking for the 58.mm piece and i just wanted to see how big of a difference it would be but i couldn't find anything. At first i thought it would be the piston rod, i measured the piston rod from the top of the crankshaft to right under the loop on the piston rod and it was really close but then i saw the crankcase had to be machined. On this crank what is bigger on it, also any good or bad news about this product will help me out. Thanks
