I'm running my bike at the peak torque figure for almost 2 hours a day (a bit over 5200rpm) at 80mph is most of the time traffic allowing.

The interesting thing though is that I don't seem to be getting the problems with the cush drive that some others are having, at least as far as I can tell.

Think I'm going to try running this past my dealer properly as changing the chain only worked for a few hundred miles (it really did work though). I need to get some new tyres fitted anyway as my front has had it.

Interesting, my cush rubbers lasted nearly 11,000 miles, and much of that was constant travel rather than stop start riding.

Off topic, but I found one of the rubbers yesterday, and it's regained it's solidity !!! not even going to think about that one! :missing:

Depending on the brand (and type), a new chain can certainly stretch as it beds-in during the first few hundred miles - especially if you didn't change the sprockets at the same time?

I'd be interested to hear what your dealer says, but one way to check might be to get the bike on a dyno and look at the graph, see how smooth it is?

It's a DID X-ring chain. Rear sprocket seems hardly worn to me. Only had a small adjustment so far (one turn on the spanner) but only done 1k miles on it so far. Using a LOT more scotoil though.. (three fillups so far, plus spray lubed it 3 times or so)

I did see from an earlier post that your bike has done 9000 miles already though? I'd imagine that is going to have significant wear on the sprockets, even with a scotoiler fitted?

I'm not trying to contradict you, only point out that putting a new chain on 9000 mile sprockets is not going to be the same as a new chain on new sprockets - it may have accellerated that intial break-in, and could continue to do so as they are essentially mismatched?

Coupled with 9000 mile old cush rubbers, well...

I know when I fitted an new chain and sprockets at around 11,000 miles with the (already worn) original cush rubbers, it ate up the new chain and sprockets within 7000 more miles... it got so bad I was adjusting the chain every day...

That said, the second set of replacements have lasted very well over a further 5000 miles (still with those bloody original cush rubbers!), although I did fit a new cush-drive bearing at the same time, which may well have helped...

11,400 miles, still on the original chain 'n sprocket & Scottoiler - like new!

anyway, shouldn't you be heading back to blighty instead of surfing the wonderweb ??

It's been :sunny: here for days now - if you don't hurry up you're gonna miss it till 2010.....:009:

Hee hee - just about to drop my luggage off at the airport in fact!

I agree scotoilers can/do significantly reduce chain/sprocket wear, what I meant that regardless of the scotoiler, I imagine there would be at least some wear to the sprockets, which would conflict with the brand new chain, hence accellerating the break-in stretch?

Anyway, I've got to go and sit in the lobby and wait for the limo... as they say (obscure Spinal Tap ref. btw.)

There certainly seems to be a wide range of experiences when it comes to chain & sprocket wear. I used to own a cbf500 which i put 13500 miles on without once adjusting or replacing the drive train, although i do appreciate that it was a twin cylinder 499cc bike putting out 50 bhp..
The Ten is a stonking great single putting out tons of torque so wear & tear on the drive train is to be expected, however, what would explain the different experiences some owners have on this forum? why would one Ten get through its chain & cogs in low miles while Gas_Up_Lets_Go managed to get 11k miles from his chain and sprockets? Any ideas?

Personally I think it could be any number of factors - inconsistency with parts manufacturing/supply (chain, cush rubbers), typical use (lots of stop start and/or off-road vs. long journeys) and quite possibly simply down to owners perception and previous experience?

Kev might have something with his idea about the EFi leaning out on a constant throttle, but personally I don't think the Tenere EFi is that clever? I've also not noticed the same symptoms at anything like the degree some people seem to have - any hunting in the transmission I've experienced is almost certainly directly due to having a sloppy cush-drive and chain...

The fueling itself has been excellent, smooth off idle and during the on-off type throttle use you experience when riding off-road. I'd be surprised if Yamaha had been able to nail that and not make it smooth on constant throttle highway riding?

ps. I apologise for the word 'highway' - guess I have been over here too long x

I'd 100% agree it is a transmission problem not fueling. My bike was totaly smooth when new, and changing the chain left it smooth as well, for a while. I'm only getting very mild symptoms currently, and as you said my sprockets and cush drive are now 10k miles old (chain 1k) so it could have been the initial wear causing the chain to stretch.

I'll certainly be keeping an eye on it. Only 2k miles until major service and new road tyres (if I can last that long on the siracs) so I'll have a good opportunity to get some comprehensive feedback from my dealer when they do all that in a months time.
