7 Degree Mount Kit 80mm X 102mm Bolt Pattern – 7 Degree Mount system with 80mm X 102mm bolt pattern for Leopard, Rotax, HPV, PRD Fireball and other popular engines. This mount system has a unique feature that allows for up to 1-1/2″ of lateral adjustment of the engine to avoid seat struts and other fitment issues while allowing for the chain to be run as close to the bearing hanger as possible to reduce the tightening and loosening effect while the Kart is in motion.
