Will you please tell me is it best to make a spacer or shave off the cylinder on my m660 I'm trying to do and how do you measure to tell if your piston is correct when you shave off the cylinder or make a spacer plate
Sorry to jump on the thread but the ts400 needs a 4mm spacer thats also a transfer block to work with a our 38mm stroke as the ts400 is a 34mm stroke ,as for the ms660 you need a 40mm crank the take about 5mm roughly off the cylinder about a mm off the deck on the block and dont forget to fill your ports and stuff your case the happy riding lemme know what pipe you decide as I'm on the fence myself was thinking a honda dio pipe not sure
Are you on any of the Facebook groups for this hobby? I’d like to inquire more information on how to modify these little engines with the Stihl top ends
