06-15 Kawasaki KX450F manual cam chain tensioner


Manual Cam Chain Tensioner

Most bikes come with automatic cam chain tensioners which are spring loaded ratcheting devices.  The problem with the spring loaded design is it can put more pressure than needed to keep proper chain tension by ratcheting in every chance it gets equaling in a overly tight chain that will decrease response, horsepower and chain life.  TD’s Manual Cam Chain Tensioner is not a ratcheting device and does require to be reset often.  It comes preset with the proper amount of force needed to tension the chain correctly and it will not move.  By pre-loading the cam chain guide correctly you will typically see a gain throughout the RPM range and a major increase in response of the engine. Other manual cam chain tensioners on the market require the mechanic to guess at the best tension just by the feel of the adjuster screw.  Repeatability is difficult with set screw type of tensioners.  Manual cam chain tensioners do require maintenance as the chain stretches, but will be much less likely to fail than the automatic chain tensioners. This is a race bike part and is not to be installed and left for months. If you are serious about racing and have the skills to loosen and tighten a set screw with the engine at top dead center this is the race part for your bike!!!
