Post Updated S1000RR/S1000R Cam Chain Tensioner Screw Plug Info






Right. This information is old hat and dealer's should be aware of it. It is not a secret.

The bike comes with a Black screw plug for the cam chain tensioner. The problem is a noisy cam chain at start up where it rattles quite loudly. The chain stretches over time and the tensioner no longer provides enough pressure to keep the chain tight.

An updated screw plug that is longer is the fix. The new screw plug is Silver. This can only be fitted after 15,000kms. It is not the tensioner itself but a longer screw plug that puts more pressure on the tensioner.

It's only if the bike has a start up cam chain rattle. This is not a be all and end all noisy fix as most people seem to have a problem with the noise on these bikes. The dealer would not just replace it if you ask. They would have to determine it has a start up rattle and then proceed accordingly. You would need to take the bike to a dealer complaining of the start up rattle. Do not replace the part if the bike is not rattling on start up. It's not an automatic replacement once you hit 15,000kms. Read my original post carefully before anyone starts jumping to conclusions. Replacing it prematurely could also cause damage and make the chain too tight.

THIS IS NOT A FIX FOR NOISY OR TICKING ENGINES IN GENERAL.

Curious why only after 15,000kms?

That is when Germany has decided it is needed. They built the bike. They tell us when.

I have 16k miles, so this means I just go to dealership and ask them to replace the tensioner plug? Covered under warranty for 15 RR?

From Benny's post it is when the cam chain stretch is likely to have occurred to a degree justifying the change.

Yes mine rattles when it starts for 1-2 sec then quite. I believe I will try at the dealer when I finish paintjob and some other things I want to do.
