PSR Manual Cam Chain Tensioner 07-02000-29 — Yamaha YZ / WR / YFZ 250cc-450cc 2004-2023

Product Description

Eliminate the risks associated with failing OEM automatic tensioners by upgrading to the PSR Manual Cam Chain Tensioner. Designed for riders who demand precision, this tensioner replaces the factory automatic or hydraulic system that can often lead to premature engine wear or "cam chain rattle" when the factory unit fails.

CNC-machined from high-quality billet aluminum and finished in a sleek gunmetal coating, this manual tensioner is built to handle the rigors of off-road and track abuse. By allowing you to manually set the proper chain tension, it permanently solves timing inconsistencies and provides peace of mind that your engine's cam timing will remain consistent under any riding condition.

Frequently Asked Questions

Q: How do I properly adjust this manual tensioner?
A: After installation, tighten the tensioner bolt by hand until there is no slack in the chain, then back it off slightly (usually 1/4 to 1/2 turn) to prevent over-tightening. Always follow the manufacturer's specific procedure for your engine.

Q: Why would I choose a manual tensioner over the OEM automatic one?
A: OEM automatic tensioners can fail due to spring fatigue or hydraulic pressure loss. A manual tensioner provides a fixed, reliable setting that cannot collapse, ensuring your engine timing remains perfect at high RPMs.

Expert Pro-Tip: Never overtighten a manual cam chain tensioner. An overtightened chain will stretch rapidly and put extreme side-load pressure on your camshaft bearings, potentially causing premature failure. Always set the tension while the engine is at room temperature.
