JaseR 213 Posted October 16, 2013 Share Posted October 16, 2013 This morning as I was pulling away I heard an intermittent clunk coming from somewhere by my feet. It appears to happen only when power is being applied as if I pull the clutch in or throttle back it stops. Anything over about 20 mph means I can't hear/feel it but I can't say I've noticed it before as I normally wear ear plugs and I've not been on the bike for nearly a week. I cleaned and checked the chain about 100 miles ago and can't say I noticed anything wrong with it - about to phone the dealer and have a chat to them about it. Link to post
roddy 845 Posted October 16, 2013 Share Posted October 16, 2013 Definitely go back to the dealer and get them to look at it. 1 Link to post
Guest robin Posted October 16, 2013 Share Posted October 16, 2013 Did you tighten the chain. If so untighten it again. Link to post
michael 324 Posted October 16, 2013 Share Posted October 16, 2013 While I was tempted to say "go faster," it seems as if you've already received better advice! Link to post
JaseR 213 Posted October 16, 2013 Author Share Posted October 16, 2013 Spoken to the dealer, they're happy to have a look abd have suggested a stiff link. And yes, I tightened the chain to take up the slack... (but I didn't notice any clunking before, which didn't mean it wasn't happening) Link to post

And yes, I tightened the chain to take up the slack... (but I didn't notice any clunking before, which didn't mean it wasn't happening) If you look at the manual, there is meant to be quite a lot of slack. I tested mine thinking it was too loose, but it was just right according to the book. 1 Link to post
JaseR 213 Posted October 16, 2013 Author Share Posted October 16, 2013 Aye, I think it might be a combination of tight chain and a stiff link, I'll see if I can unadjust the chain later Link to post
Guest Dron Posted October 19, 2013 Share Posted October 19, 2013 I had this too, but it went away after lubricating chain well, so reckon it is likely a chain problem of some kind you are having. Link to post
JaseR 213 Posted October 19, 2013 Author Share Posted October 19, 2013 Checked the chain and had a couple of stiff links which enjoyed some more oil and I relaxed the chain tension and everything seems okay.... Link to post
Guest nc700ls Posted January 25, 2014 Share Posted January 25, 2014 I have this problem too, thought it was a problem with the chain but after having this checked a number of times it seems to be the rear cush drive Link to post
Rev Ken 6,331 Posted January 26, 2014 Share Posted January 26, 2014 I have this problem too, thought it was a problem with the chain but after having this checked a number of times it seems to be the rear cush drive Sounds a possibility. When getting my fourth set of tyes at 20,000 miles (CBF1000. There was still some meat on them but I was off on a European tour) I was shown the rear cush drive - a rubber 'spider' - and was complimented that it was still in one piece as apparently they do fail, particularly if gear changes are not smooth. Not that I'm suggesting you're one of them! It confirmed that my clutchless gear changes aren't abusing my gearbox and rear drive. Link to post
Guest nc700ls Posted January 28, 2014 Share Posted January 28, 2014 I've only just bought this bike one of triumphs used bikes and they are being difficult about the problem. The cush drive is not covered under the Honda warranty either. Link to post

The cush drive is not covered under the Honda warranty either. It is a simple diy job as you just take off the rear wheel, take out the rubber cush drive, replace with a new one -I don't know how much they cost, but it SHOULDN'T cost much. That is for a CBF1000 , but I would be surprised if the NC series is different. Link to post
Guest motorboy Posted January 30, 2014 Share Posted January 30, 2014 You need to keep an eye on that chain once you find stiff kinks that it.Oil can not get pass the O rings to lube the pins that are dry it will only get worse. Link to post
Mike5100 2,061 Posted January 30, 2014 Share Posted January 30, 2014 Yeah on my 700X I thought I could save the chain which had several stiff links by liberal application of oil, but over the next 100 miles or so, red dust (or rather red sludge) was evident on the swingarm - particularly where the chain hits the nylon guide.

Guest nc700ls Posted March 7, 2014 Share Posted March 7, 2014 It turns out after finely getting triumph to agree to sort the cush drive that it was a ceased link in the chain, so they replaced the chain and sprockets and lubricated the cush drive, so redeemed themselves in the end Link to post
