Parts Manual Cam Chain Tensioners
APE manual cam chain tensioners
are designed to replace the automatic and hydraulic tensioners on high
performance engines. The automatic adjusters can back out when the throttle
is closed suddenly at high rpm. This allows the cams to go momentarely
out of time, and can result in bent valves and/or serious engine damage.
Hydraulic tensioners have a tendency to put too much tension on the chain
guide under high rpm/high oil pressure conditions, resulting in premature
Both problems can be eliminated
with the installation of the APE manual tensioner. No mater what the engine
does, the cam chain tension will remain constant. An APE manual cam chain
tensioner is a must for any kind of performance riding.
APE manual tensioners
are CNC machined from billet alloy to exact tolerances for perfect fit.
* V-Twin and V4 bikes
require two chain tensioners (one per side).
