• I don't think it's actually that hard to get the cylinder head off on a Vespa. Quite what I'm looking for once I'm in there is a bit of a mystery, though.

    If I don't see any scoring I guess I'm ok. Otherwise...

  • It's a piece of piss but make sure you torque down the cylinder head correctly and evenly after, I didn't do that once and it ran like shit until someone who knew what they were talking about sorted it out for me

  • What am I looking for while I'm in there? Just scoring on the cylinder walls or any obvious damage? If there isn't any, what's to stop it happening again? Is that where the fuel filter comes in? Does that sound like the likely culprit?

    If I do see damage then I may just have a little cry and wheel it out on to the street with a sign saying "Free Vespa (warning, it's a total lemon)."
