I was just wondering if anyone had some tips on performance upgrades on the 550. And i also wanted to get some info on clutch kits or mods. I want as much low end as i can get.. I dont care much about top end. I had heard you can do some simple shim and spring changes to really help the gear ratio down low with out buying a full blown clutch kit. I was looking into some hmf exhausts or just tip replacement and maybe a ecm controller or something. thanks for any help
