Hi all,

I am having a hard time finding any vender that sells a 40mm crank, all cranks for sale right now are 38mm. Some site like Dave over at arrowmotorizedcycles and fred st cr machine have 40mm cranks but they're over $100.

Does anyone have a 40mm crank they would like to sell me?

did you consider getting whole 40mm motor & kit for maybe $140 or so and have a bunch of spares?

I'm not certain that the port mapping in a cylinder for 40mm stroke is same as for 38mm stroke.
