Is the timing chain tensioner on a 2008 KTM?
The 2008 and newer four-strokes use a timing chain tensioning device intended to develop its force using the engine oil pressure hydraulically. The OEM components have serious flaws, which can leave the timing chain in a slack condition. This can have disastrous consequences.
When to adjust manual cam chain tensioner when hot?
Most people say to adjust it just until the “rattle” goes away when hot. The problem is, I don’t hear any rattling or wooshing or anything even when the tensioner applying no pressure at all (ie. the screw is totally loose and not touching the chain guide).
How do you adjust the timing on a cam?
The cam chain tensioner comes out and a tensioner tool is inserted. The tool has an inner threaded and spring loaded plunger that is tightened a specified amount to put the appropriate tension on the cam chain. To adjust the timing the two 16mm screws that attach the cam gears to the camshafts are loosened so the cams can be rotated by hand.
What happens when the timing chain is off on a Moto?
Cam timings that are off several degrees will result in a loss of power and the cam chain tensioner will have quite a job trying to take slack out of the valvetrain. When a timing chain elongates it may not do so in a uniform way and parts of the chain may be tighter or looser than others.

Can you use an OEM chain tensioner on dirt tricks?
The OEM components have serious flaws, which can leave the timing chain in a slack condition. This can have disastrous consequences. The Founder of Dirt Tricks developed our timing chain tensioner as a simple, effective, and fail-safe replacement for the OEM tensioner.
What does manual mean on a timing chain?
Manual means just that, you have to be diligent in monitoring timing chain slack and manually adjust the tensioner to compensate for wear. It’s also possible the mechanic over tensioned it, causing it to wear faster. You won’t know what let loose until you get the head off.
