Fast and fun with plenty of torque. Less shifting than a 2-stroke with a wider range of power plus runs on premium pump gas (91) with standard compression. Very clean and low hours.
Chassis is a GP8 with front brakes, Tillet (large) seat, large radiator and two sets of wheels and tires. Has a Micron 4 installed. Engine is a 2006 CRF 250 motor and five speed gearbox. Internal water pump. I installed a modified crank-case side with the ability to use a electric starter (handheld) from the side (includes original case too). It will start like a conventional shifter too (pull strap or bump). A HD Coleman starter with new battery is included. Also included is a KartLift single person lift and stand.
I also am selling a GP7 roller chassis (w/ front brakes).
$3000 or offer. Also willing to trade for new-ish 100cc chassis suitable for WF motor or trade for WF motor (more my speed!).

I have a Sodi Kart that looks brand new with a world formula motor on it . It has a 32 mm chassis with a 50 mm axle. I also have a 2008 crg with a parilla leopard that might be up your alley. Let me know if you have any interest in either of these karts for a 250 shifter trade.
