Re: im thinking 99cc??
I'm pretty sure you can still get a 99 in california. I've read they sell em there. Anyway, the motor will have different width depending on the transmission, but yeah, its a bit wide. You will probably need wide cranks. If mounted right you wont. Do you have a harbor freight near you? Go check it out, they should have em out on a table somewhere.
