[1upfront]

I just bought a 300r cylinder and head but the outer fins are shaped different more rounded, also the head is skinnier than normal just wondering if anybody knows anything about there being more than one model of 300r kit. Heres some pics.

I only knew of the hondaline kit. They did have the Mugen 360 kit. Do you have pics of the outside of the cylinder and head?

Looks like someome wanted a sleeper. Trim the fins to make it look like a stock 250 top end.

Could it be a cylinder and head from one of those Honda gokarts? I think some of them had 7 stud heads/cylinders also...

Nope the one on the left in the last picture is one of those for one of my future projects and it's much bigger.
