My new go kart engine.

A modified one, probably. I'd probably spend twice as much modding it to get to 12000RPM and 120HP as building what I got.

Ahh well, good lesson to learn from anyways.
 
My fuel injected 03' CBR600RR was rated at 119hp from the factory.

Do you run 87 octane and no additives or power adders because of class rules or something?
