i never quite got my head around the 2 stroke inlet exhaust port opened at the same time argument against 2 strokes.
if this is the case, then why is it that the fuel air charge doesnt just rush straight out of the exhaust port under normal circumstances? because the reflected pressure wave from a
tuned pipe forces some of the mixture back in.
all forced induction would be doing is to just add to the effect that is already present. how is it any different to adding a bigger carb to flow more air or changing to larger area reeds to let more air in etc. if you tune the pipe there should be no issue to charging at all.
as for the reeds closing under pressure my understanding of a reed engine is that the valves open as the piston draws near TDC to fill the compression area with mixture and closes as the piston draws near BDC to compress it. during the compression stage the pressure will still be higher in the compression chamber than on the carb side of the reeds closing the reeds like normal. once more thats just the same as normal operation. that is of course if my understanding of 2 strokes is up to speed
i should think with your average pipe the power band would be shyteloads narrower but if you used a CVEC style adjustable pipe then the gains are there to be reaped
im getting a small smog pump off a car this weekend to setup a draw through supercharger so we shall see how that goes in a reed engine.
not to be one to shoot my mouth of before first hand experience here is my
supercharged nitro car with cvec pipe. (even with a stock pipe it definitely hauls alot more *** than before!) mind this is a piston port style engine.

Edit - BTW sirhsv check out ebay at the moment for bike turbos or kei car turbos. theres tons on ebay for not too bad a price when i was haveing a quick looks ($300-400). if your x bikes are 4 stroke then yeah youd have no issues running a turbo on it. provided there is some pressurised oil supply for the turbo. might have a bit of lag on a 110cc engine anyway
ever seen the turbo vespa?
