Manual Primary Chain Tensioner Directly replaces the factory automatic adjuster in order to allow manual adjustment. After accumulating a certain mileage, the original primary automatic chain tensioner wears out, so that the main chain cannot be kept in the proper tension at all times. Over-tight or overly loose primary chains can cause premature failure of the gearbox, and replacing the manual tensioner can solve this problem. Features: -You can fine-tune the tension of your primary chain as you need to avoid excessive drag and power loss, ensuring smooth operation and unparalleled riding experience. -Allows correct manual adjustment of the primary chain to the factory specifications. -CNC machined from 6061 billet aluminum for superior strength and hardness. -Extend primary chain life, and get the most power from the motor. -Requires removal of the primary cover for installation or adjustment. -Uses the OEM mounting hardware.
