What mods have you got Adam?
Its got a K&N filter, some odd system that gives it a triple spark! (the theory sounded good when it was explained)and a mongoose/powerflow exhaust sytem, coupled with regular servicing. I'm not sure what else was done prior to me owning it, but it was owned by a mechanic!
when the new wheels go on, the wheel radius will be smaller too, so it should make an improvement I've been informed.
I dont really use it for racing about in though - I just like to pose
