Good To Know

Q: Can I install this kit without a machine shop? A: Pressing the crankshaft apart and truing it afterward requires a hydraulic press and dial indicator setup. A: Most riders have a qualified shop handle the assembly.

Q: Is it worth rebuilding the top end at the same time? A: Because the cases must be split for crank work, many builders refresh pistons and bore work together. A: Check cylinder and piston condition first.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
