How do you install a dirt bike motor on to your go - kart frame?

A friend of mine races a class of mini-sprint cars that use a 600-650cc motorcycle engine. they are extremely fast and alot of fun to watch. The pits at this type of race are usually open to spectaters where you can get up close and personal with the drivers and the mechanics. I would recommend to you to find such a race and attend one to talk to the pros before you say the famous line " Hey ya'll, watch this...". good luck, and be safe!----lynn.
