Default Re: what did you do to your motor bike today?

tuning my new expansion chamber-I ordered it from a pit bike e-store $22+$15 s&h it fits between the cranks had to re bend the head pipe it's coming on between 10-30mpr motorized bicycle clime pretty good-I only cut 1/2in. off the head pipe I don't think I'll cut any more but I'll open the stinger as the exhaust was for a 48cc. my motor is a 66cc. the silencer kills the the power as the tip is so small I'll open it to- I think I'll be able to run it with a 40t or a36t gear now and that's what I am going for
