Honda CB750 Cam Chain Tensioner – High Performance MessnerMoto
This, Honda CB750 cam chain tensioner – High Performance, is an implementation of modern engine cam slider and tensioner design for CB750 SOHC engine. This cam tensioner system allows for total control of the cam chain. Due to the curvature of the guides, all resonance is eliminated as the chain remains in full contact over its entire length of travel. All of this will allow far better control and stability of timing across the rev range. For the racing application, this system will allow for higher rev range and it will prevent common failure/breakage of the cam chain. For all racing CR750 Hondas Camshaft chain/tensioner failure was one of the most common failures during races. This Camshaft tensioner system solves this week spot in CB750. Sliders are CNCed from PA 66 + MoS2 polyamide. Stainless steel plates are laser cut. Load on cam chain is decreased because of constant contact between chain and guides. Combined with state of the art material used in construction this will increase service interval of cam chain and reduce wear of complete system. HD chain with straight side plates is a must for this system. The number of links in the cam chain is increased from 94 to 96 links to achieve the desired curvature in chain guides, compared to original cb750 cam chain. One beneficial side effect of this system is a lowered noise from the cam chain.
