    Me too Bob. One thing about Lambrettas, you quickly learnt how to repair engines , usually at the side of the road with minimal toolkit...
    The Rotax bottom ring tends to gum up at one point only - immediately below the top ring gap, where the blow-by occurs. So even when it sticks, it's only on a small segment, leaving the rest of the ring free to expand. The only thing about leaving the job for too long (and I agree with your 200hr), is that working it loose again at the decoke runs a risk of breaking it (and subsequently the bank when you call CFS for a replacement).

    A pretty good test is to look into the exhaust ports whilst you have the muffler off for a wire brush and a VHT respray (about every 100 hours). You can get a good look at the rings and even prod them to see if the exposed section moves in its groove.
