Use to rotate the front or rear tire. Have you ever wished you had a third hand? Well, with this Jims tool you do. Think about the possibilities of being able to put your motorcycle in high gear and turn the rear wheel with one hand and having the internal engine parts rotate. Check tappet adjustments, check cam timing, ignition timing, check primary chain adjustments, rear belt or chain adjustments, check spoke torque and install or remove any part or parts that need the engine rotated. Can also be used for finding the air fill and cleaning the wheel or tire. Ratchet, drive extension and socket not included.
