Freestyle What cylinder code is this?

[djraider700]

Was checking out a Blaster that my friend has and am confused on its cylinder code. On the cylinder, where you would usually find 61x or 62t, it says 6F 00. On the bottom of the cylinder near the base it has "760cc" written in marker. Riva non-girdled head. Sitting on 62t cases with a single carb manifold and Riva 48mm Power Bomb.

Is that a 760 cylinder code? I always thought it was 64U or something. Anyone know?

Also looking for carb specs for his setup if anyone has something similar.

Thanks!

best shot i could get



Can barely see it, but it has 6F on top and 00 on the bottom

That would be a 760 64X cylinder with the 6F 00 stamp code and the term 64X is commonly used because the part number for the cylinder starts with this.
