1. The only proper way to do it is with new pistons which have a higher dome. You can shave the head but this is a bit dodgy as it interferes with the cam timing; remember it's an OHC engine, so if you effectively lower the height of the cylinder head, you're making the path for the timing chain shorter.
2. Cheap and easy? Not much apart from the usual extractors and exhaust. For worthwhile gains you can either spend a small fortune building a high-rpm atmo engine, or you can spend a modest amount on a turbo setup. You already have the perfect compression ratio for forced induction, so I know which way I'd go!
3. Definitely not! Replacing EFI with carbs is a serious backwards step. 50mm sidedraughts on anything less than a full-house race engine would be just silly. However if you like spending lots of money on fuel, go for it.
