After having carburetor issues, I figured I’d pull off my Athena kit to see how it was holding up. Piston clearance had come up in a conversation Saturday night and it turns out it was a good idea to pull the head.

The piston isn’t always hitting the head, I only heard it on long, wide open downhill stretches maybe when the rod and piston expand a little more than the head and barrel.

Anyway, this has me researching ways to improve clearance like squish band, adding head or base gaskets…
