G650 Sertao chain tension adjustement - on centre stand or side stand

[timob]

Hiya,

Can someone help me out. I have been taking up the chain slack on my G650GS Sertao regularly - to the point where I am seriously thinking something is wrong. Its a 2012 with 4400 miles on it when I bought it - Its now nearly got 9000 miles. I use it a lot green laning

I have been finding the tight spot on the chain and adjusting as the guides on here and F650.co.uk site, however this I have been doing on the centre stand. The user guide says 40-50mm on the side stand but I notice on the F650 service manual is says to do this on the centre stand.

Have I over tensioned it by putting it on the centre stand and hence why I am seeing all this stretching?

Thanks

I do/did mine always on the sidestand. I recon maybe best way would be to sit on the bike or get yer fat mate sat on it to flatten the suspension down the just leave a bit more slack for spare. - Then check what it is on sidestand after doing the above and it came out as the recommended 40 - 50 mm of slack movement when on flat ground and on sidestand mine has slackened over the 14k but not by a lot and mine gets thrashed quite regularly

Having had several OE chains on several xchallenges that I have had, I found that frequent adjusting was an indication that it was nearing the end of its useful life. Green landing wears them out pretty quick. Mate with a sertao has also found this. 5k miles on the OE is the most we have managed when laning.

I'd recommend replacement with a decent chain and sprocket kit (o or x ring).

What he says

Plus ....side stand, centre stand, loadoad or unloaded ??

At the tight spot check your chain tension which will be at it at its tightest when the gearbox sprocket centre, the swing arm pivot centre and the rear wheel spindle centre are all IN A STRAIGHT LINE ... any up and down movement from this straight line and your chain becomes slackererererer

Fitted it with a new DID X ring VX2 chain and sprockets, was getting worried it was going to give out. Oh and I hadn't had the front sprocket cover of for a while, when I did I had some fairly hooked teeth!

Micky - on the swing arm it says 40-50mm slack with no load. I take it your comment on having it loaded so the rear wheel spindle and sprocket centre in a straight line is just to check there is some free play as 40-50mm at this point would be way to slack?

Thanks

BMW have to generalise .... but in a nutshell, for more precise checking, doesn't matter whether your bike is loaded or not, side or centre stand ...

When the gearbox sprocket, swing arm and rear wheel centres are all in line the chain will be at its tightest. Any up and down movement of the rear wheel from this straight line will make the chain less tight!!

You'll have to load up, or unload your bike, try either stand, until theses centres are in a straight line

Loose is much better than tight

Centre stand for me & then sit on it afterwards - lean down & check the tension

I ignore what BMW says though

I was running (wearing out) two front sprockets to one rear.

The TT sprocket cover is more open and stops crud getting caught - and ignored.
