Check out the exhaust forum, alot of folks have done alot of
different things. Remove the AI, pull the snorkle, add, or mod
pipes, re-jet adjust and balance the carbs. You'll be surprised
with the results! Let the motor breathe. Check out Dinqua's
(Pat's) jetting calculator in the "Tach Vault". There's tons
of priceless info here on this site.

Oh yeah, welcome!
