Oh dear... so what do I do now?

Pete rode over this afternoon and gave my rear cylinder head the OK... but once we'd got the cylinder off and Pete had removed the piston (seems to be a Shovelhead piston with the later spiral keeper), the evidence of heat damage was finally revealed.

The piston and cylinder wall are toast. Even better news, the cylinder is at the end of its life: already .070 over.

My fault really, for pushing a sick bike 200 miles to the Linkert.

So, what now?

I have heard that sleeving cylinders can be dodgy. I have heard that aftermarket cylinders can be dodgy. So do I try to find some used OEM cylinders and pistons? Would they have to be early cylinders to work with the '52 bottom end?

Panhead owners, I need your opinions.
