Zipper’s Sportster® Cam Clearance Tool

Use this tool to provide clearance for high lift cam lobes in ‘91-up XL/XB Sportster®/Buell® engines. This tool will quickly machine precision cuts on the pinion bearing boss and the tappet bore housing undersides of the case. Can be used on the engine case in the frame with a 1/2” drill or in a milling machine with a disassembled engine. Installing high lift cams in 5 speed Sportster and Buell engines usually requires the removal of some case material at the base of the lifter bores and around the pinion bearing for lobe swing clearance. Doing the job correctly required splitting the cases and a milling machine; a lot of work! This tool cuts clearance quickly and can be used on an assembled engine.

Does not work on 2008-2010 XB models and 2008-2012 XR1200 models.
