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 wear.
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.
