Just some thoughts:
A turbo would require flat-topped, forged pistons to drop the measured compression ratio. It would be wise to also do a number of engine-strengthening mods : Shot-peen, or better still, replace rods with Carillo or similar. Are the cranks pressed? If so, weld. Heavy duty valve springs. Heavy duty clutch - not sure what would be best type. Adjustable waste-gate and know what you can set it to, and how to do it by degrees until you reach what you're happy with/won't blow the motor. It may also require some attention to strengthen the gearbox, but I have no idea what you could do in this regard. It's possible that a supercharger could be a better idea, so worth looking into. Nitrous to me seems a pain, as you're always going to be needing top-ups if you use it much, whereas a turbo or supercharger is always just there.
It's not going to be the most common of bikes chosen for these kinds of mods, so don't know what the availability of such parts would be?
Back in the day, people also did "conventional" tuning: hairy cams, big bore kits, smoothbore or flat-slide carbs, porting and gas-flowing. It's generally agreed that such engines were pigs for road use - won't idle, snatchy and bog down until you get them on cam, etc. However, there were some notable tuners who could do a half decent job of it, John Carpenter of Mistral fame is the only one I can think of.
I wonder if modern parts and techniques have improved matters in more recent years?
It seems almost a shame to have all that beautiful chassis work done and then a have a near stock motor, so you've gotta do something to pep the engine up a little!
Dare you tell how much it has cost so far? :eek
