[LEEEZARD7]

purchased a used kenbar sta9 about a week ago. it had a briggs 5hp with comet series 30tav on it. i built a custom briggs 8hp 320CC motor for it. removed the govenor, installed a bearing side cover and bearing for the crankshaft for some serious rpm's. i flycut the head .015 to raise compression. (i am a machinist and have my own shop) i made an aluminum intake to run a mikuni 27mm dirt bike carb, put on a 1.25" diameter straight pipe exhaust i also made and re installed the comet 30. made my own throttle cable and mounts from dirt bike parts. its up and running now and it flies... the go kart is for my 10yr old daughter and she loves it... it might be a little too fast for her but she seems to be cautious.
