6mm Spacer w/ 54mm Stud Spacings

If you are running a 8.2mm stoker crank shaft and your cylinder doesn’t have a built in spacer, you will need to space your cylinder so the piston doesn’t travel higher then the cylinder and hit the head. This is the proper spacer you will need for your GY6 A (54mm stud spacing). You will need 2 base gaskets to seal this up rather than 1.
