The Parallel Twin is a fairly new engine. Most owners would scrap the bike if the engine was worn out or blown. I've rebuilt 2 engines now and have a spare transmission laying around, pistons and cylinder heads etc. I don't think these parts have much value because very few would ever need them. On Ebay, there's a bunch of wreckers who tore down good engines and are trying to sell the parts for a small fortune. So I was wondering. Who here has removed their engine for extensive work? Any tips or tricks to make it easier? Should I plant flowers in perfectly good cylinder bores?
