SX/SXi/SXi Pro Question on 750 big pin, small pin cylinders

[mattchow88]

are the cylinders interchangable from big pin to small pin motors or vice versa, i know rod center to center is the same but is the throw the same,or will it screw up port time?

 

[w-nut]

yes you can run a big pin cylinder on small pin cases and vice versa. im running a sxr cylinder on small pin cases and it works great .

Port timing is the difference from big to small
