Anyone know if a eton viper cylinder can fit on the lower half of our motors? Normally a 90cc motor.

Thats a case reed cylinder that uses wider stud spacing and the stroke is longer so pretty hard to do!

Hey what is the stud spacing anyway I never bothered to measure and I'm still too lazy to do it now.

45mm for the 66cc I forget what the 48 is but 40mm comes to mind!

And that's a perimeter measure not diagonal across the bore right?
