Just wondering what the differences are between the early piston port pistons as opposed to the 74 and later pistons?? Wiseco does a 74 later kit.

Biggest issue is windows in skirt.

Check with Enduronut. He likely has what you need. Or post here and someone else might.

Now i'm sitting up & taking notice. Tell us more about ya bike. I expanded your pic & looks great in action. Tank looks RT2. What cylinder are you running, a piston port DT1mx cylinder or a DT1 GYT race kit chrome cylinder "like i stuffed running wrong ring against chrome, doh!!" Or did you port your original cylinder. If its a borable cylinder what size are you after, 70.?--i'll go searching.Sorry for the annoying questions. One more, where are you situated--i'm in NZ & see mud in the pic so looks like home to me.
