Supercharging & Bike Throttle bodies

How would you go about Supercharging an engine on Bike Throttle bodies? obviously you would need supercharger, intercooler, plenum etc, but would the throttle boddies need any special modification etc?

Depends how much boost you're planning on going for. Lots of TBs will take a little boost but most will leak if you go for big PSI.

I've gone for a single RS Turbo TB (ie something designed to take boost)....

i've always wondered how difficult it would be to enclose all the TBs (maybe easier with carbs) in a ali airbox which is all underpressure with filtered air inside, so the pressure is the same inside and outside the carbs

The only air leak that I have noticed is on the idle bypass on my 954 blade TB's, beyond that its a straight tube with butterflies and injectors pointing in.

The idle bleeds air from around the mouth of the trumpets, I just use the butterflies to regulate idle now when warm, cut off the cold idle bit that was a stat thing.
