The Drain Posted October 17, 2009 Share Posted October 17, 2009 Ok, I'm not sure graunching is a real word!A few days ago I noticed my bike was making a few graunching noises, a sort or rattling snatchy grabby noise, especially when pulling away or after changing gear. It actually sounded as if something was loose, but I have checked around and found nothing.So I decided that perhaps the chain was loose, and it did seem to be a little slack. I adjusted it up a little, not too much but it is now on the tighter side of the scale rather than the slack.And all I have done is turned the noise from an irregular sound when pulling away to a regular one that gets more frequent the faster I go. Could it be something funny with the chain itself? I shall loosen it off slightly tomorrow just incase I have nipped it up too tight.Otherwise I am stumped, and would be very grateful for any advice.

Guest Posted October 17, 2009 Share Posted October 17, 2009 When was the last time it was lubed? Quote Link to comment Share on other sites More sharing options...
The Drain Posted October 17, 2009 Author Share Posted October 17, 2009 A week ago...And its about to be tomorrow!Would that produce the regular grr...grrr...grrr.. noises? It seems to be doing it each time the chain goes around in a certain spot. Quote Link to comment Share on other sites More sharing options...
Colin the Bear Posted October 17, 2009 Share Posted October 17, 2009 Probably a problem in that particular area of the chain. Worn, seized or stretched. Quote Link to comment Share on other sites More sharing options...
Guest Posted October 17, 2009 Share Posted October 17, 2009 sounds like it could be a tight link, or two. If you can get your bike on a paddock stand or mainstand, revolve rear wheel by hand backwards. Keep an eye on the chain as it leaves the sprocket, if you have stiff links, they should show themselves here. Im my experience that is!! Normally characterised by the links looking like they want to stick the sprocket. Assuming this is the case and you don't have an underlying problem elsewhere, it may be possible to free the links with a couple of pair of pliers. Free the offending links up, re lube, and see how you go.And have you read this?http://www.themotorbikeforum.co.uk/view ... =5&t=21360 Quote Link to comment Share on other sites More sharing options...
Guest Posted October 17, 2009 Share Posted October 17, 2009 also if you have adjusted it, is it lined up correctly... Quote Link to comment Share on other sites More sharing options...
The Drain Posted October 17, 2009 Author Share Posted October 17, 2009 also if you have adjusted it, is it lined up correctly... Yes, as far as I can see, I took great care when doing it and it should be as near as can be. Quote Link to comment Share on other sites More sharing options...
