Pro bought as pol exec. w/200 miles and warranty. assault had 2300 miles with no issue's until last trip to cooke. mag. side rod bearing. pro now has 530 miles with two new short blocks since he bought it jan. 3,2012. both times pto bearings. great dealer in moose lake mn. got warranty on pro untill april 2013. bottom, is the gizmo a top end "fix"? or does help the bottom end also. assault was bought new dec. 2010 so warranty covered me also. (2 yr. engine contract). planning on spending 6 wks. in cooke next winter, hopefully riding, not wrenching. any help/info is greatly appriciated.
