performance for 200s

[panteramatt]

Im restoring a 200s for a friend and rebuilding the motor. It has a open airbox with a k@n and a dg exhaust. Im planning on puttin a 10.5 compression piston in it with a 200x cam and a 12t front sprocket. Are these good mods for it? Any other ideas?

with that much power Id probably want a better clutch, Don't know of anyone that makes these?

Yea already did all the mods and a bigger carb and found the clutch wasnt good enough so Im replacing that and stiffer springs.
