Cam chain tensioner
« on: August 28, 2018, 12:55:24 PM »
Hi, my bike makes a racket when started up for a second or two, probably the cam chain tensioner.
I'm looking at the manual ones but the ones I can find for the s1000xr seem to be double the price of the ones for the s1000r ! But surely they are the same ?

It will also do it if you put 10/40 instead of 5/40 hence the recall on on the K model when they changed the oil spec.

When I bought the bike it had 5w40 oil in and it rattled badly at every start up, I changed the oil to 10w40 and now it only rattles at the very first start of the day.
Not sure whether to buy a manual cct or buy the updated silver cap from BMW.

The admin needs to start another section for ‘How to do’ or sticky threads as folks go more DIY

Google ‘Cuban rider booster plug fitting’

If you are goingto be doing more of your own maintenance, I advise you to buy the Haynes manual and.or the service DVD(some say this is cumbersome to use, which it is the 1st few times, but as you use it more it becomes easier to navigate around)

First 2 seconds are always going to be rattly as the tensioner primes itself with oil. After I'd put in the modified tensioner, it went a lot quieter (but still with the noisy 2s start-up)
