Just bought a 2006 A/C 500, it came with 14" ITP wheels and 27" Zilla's. It's got a black magic exhaust, and apparently its jetted. My question is; I dont know/think that the machine has a clutch to match the tire and rim package that it has. I don't know to tell if its clutched or not. The machine seems fairly doggy on the bottom end and has no top end, seems to max out around 40ish km/h?
