You can do any number of things. A stage 2 carb kit would be a start. A set of aftermarket heavy duty clutch springs are a must with any power mod on this bike. I highly reccomend you visit, and join the Marauder Intruder group at Delphi forums. MIG for short. That is THE place for anyone who owns a Marauder. I highly reccomend you stay away from any aftermarket jet kits that have steel, or titainium needles. You WILL regret it.
