Try eBay. Type in used Victory parts. Pick high price to low. There are quite a few motors there. Starting from $2500.00 and down from there. And what happened to have a engine failure?
The piston came apart in the wrist pin area, rod shot out of front of engine case,snapped mainshaft at clutch. The local dealer said bike had slid on right side and starved for oil. That happened over 2000 miles ago. Thanks for tip.I'll look on Ebay wrench smurf
