Its an Azusa minibike kit with a Tecumseh PowerSport 5HP engine & MaxTorque clutch.I've added a K&N type air filter with an aluminum mounting cup.I fabricated my own exhaust for it also.I can run either a tube type muffler or a straight pipe.I've also changed out the one piece 72T rear sprocket assembly with an Azusa rear brake hub & a Horstman 60T split rear spocket.I'm guessing im getting between 35-40MPH out of it.Maybe more
