A high lift cam cam such as the 575 will stress the springs and wear valve guides prematurely. Not too mention the added stress on the bottom end. Miss a high rpm shift ,could be a problem. A 527 would give plenty of useable power if setup correctly............................

 

My ride stage one is jackpot downpine, se heavy flow breather, rush 4 inch slip ons. Cam install included 575 RS cam, adjustable push rods, new roller, and rs can tensioners. The work was performed by the dealer in idahofalls. I run the dyno at timp Harley in Lindon Utah because that's where the orginal dyno was run after stage one install. Just trying to minimize the varables.
