I have a 2001 Arctic Cat 500 EFI engine from a Mountain Cat. It is NOT the power valve version. I have absolutely everything to make it run, except the air temp sensor in the airbox. It has the throttle bodies, ECU, coil, Y pipe, pipe and can, and the recoil. It has about 2500 miles. Can bring to Haydays if there is any interest. Asking $700 for everything. PM or call 208 652 3416.
