I know nothing about engines but am curious what bits would be in spec and which wouldn't and therefore how much of an impact it would have on the design of the rest of the bike mods and the subsequent cost.
I doubt the radiator is the weakest link - that's an separate system and is mostly impacted by revs but obviously heat does become a concern.
First of all you'd need to modify the carbs I expect and the fuel-air mixture to take advantage of the extra air - compressed air means you can use more fuel with it to produce a bigger bang in the cylinder. The bigger bang is the problem - the pistons and valves need to be strong enough to take the pressure and so does the head and cylinder block. Not sure about bikes, but with some cars you can blow the head gasket quite easily.
I always like the whine of a Supercharger but are they even practical on a motorcycle engine? And I don't mean bikes that have had a seat welded to a car engine that some of the Americans seem to enjoy doing...
