A few considerations.
If your plan to turbo/supercharge the Savage is "for the heck of it", do it and tell us about it.
BUT
If your plan to turbo/supercharge the Savage is to gain an extra 50-60% extra power, then you're barking up the wrong tree.
A few engineering considerations:
1. The Savage is a small valve, big bore, air cooled single with well-known valve lubrication issues;
charging the engine would mean extra stress on the crank journals and bearings; have you planned to re-engineer them or do you plan to
bend/break the con rod?
2. The Savage is a big single, and charging the engine means the power down stroke would have twice, possibly three times the energy as originally designed...
yet the crank counterbalance weights are engineered for the stock 32hp at 6500rpm... have you considered the vibrations exerted on the piston pin when the piston goes
yahoo! at WOT 10-15psi ?
3. The Savage is a 650cc big single engineered to deliver a mere 32 hp; on the other hand, Suzuki's other "big single" family is the DR range (enduros)
which are available in 600-650-750-800 cc variants which deliver 37-42-52-55 hp respectively.

My three cents' worth... (there's inflation, exchange commission and overseas allowance
)
PS : I forgot... did you consider if the clutch is capable of handling the increased torque ? Primary gears in the transmission ?
