tensioner noise

[Colin]

Is the timing chain rattle on the left hand cylinder on start up with a warm engine doing any harm, Or can the chain jump a tooth?
I see Motorworks do a modified tensioner £50 ish. or can I modify mine?
I take it the oil drains down through the little hole when engine is stopped.
I have a 2004 R850R. 26.000 mls.

Possibly out of the hole (The feed into the piston) but mainly down the grove in the piston, Straight forward mod with gratifying instant results, no more start up rattle! also found the idle smoother, guess there could be a bit of variation in valve timing at idle with little oil pressure tensioning the cam chain.


Recommend its a job worth doing.

Just done it and it makes a good difference.

There's no mod you can do to the old style tensioner.

Well worth changing to the new pattern - my bike sounded like a bag of spanners at start up before changing it and I did wonder whether it would thrash itself to bits in the end. Nice and quiet now.

Is there one or two tensioners on the 1100 GS are they worth changing and where are the little gits ???

Two.
But you only have to bother about the left hand one which is on the top of the cylinder just under the telelever pivot (B4ndits excellent picture borrowed below):

The right hand one is underneath the right hand pot and doesn't suffer the same issues as it's always in oil.

If your bike still has the original tensioner and if it rattles like a b*stard at start up, it's probably worth changing it. The original tensioner has a 17 mm head, the updated one is 15mm (from memory - if I've got it the wrong way round, I'm sure someone will correct me )

It's dead easy to change it - the hardest bit is getting to it (you have to move the throttle body out of the way and will need a ring spanner with a fairly deep offset) - there's a guide somewhere on Adventure Rider.

There are two but you only need to update the nearside one, The offside one is the other way up and the oil does not drain out.

Here's a link to a picture thread off the ADV site which pretty much explains all
