Do a 480 and from there the possibilities are only limited by your budget.

I am running a 480cc 14:1 compression piston, port and polished head by Boone450R, FCR 40 carb, HRC kit, PulseCharger exhaust with stealth core, and a Dynatek ignition.

My jetting is 160 main jet, 48 pilot jet with the air/fuel screw 1.5 turns out, remember this is with the FCR carb, not stock. :)

what's the hp lukster?

This is with a intake leak, rusted chain, and it wasn't broke in at all, it was the 2nd run on the dyno and other than the dyno it had been ridden about 1/8 of a mile. As you can see by the jetting I have made some changes too.
