1982 430CR to do what with?

Blokes in workshops...worse than bloody kids

Not everyone should have tools:

At least as a bloody kid, I was useful. My father found I was a quick study.

a quick study of the "form guide" between classes??

What I meant was that it looks like it had been RUNNING with too tight of a piston-to-head clearance. There was a service bulletin about this, but it was aimed at the 81's. Husqvarna claimed to have fixed it for late 81-newer 430's, but I've come across some 82's just like this.

You can get Cometic base gaskets for the 430/500 (and others) in any thickness they make. Great way to set the deck height on the old bikes.

yeah, no worries, and thanks for the tip

By chance, you wouldn't happen to have that 430 still? Needing a cylinder.

My dad got me out of his hair at six yo he put me washing his parts.
