Hi there,
I've got a 2004 xtx with just over 15000km on the clock. I love my bike and use it daily to go to work and back. Recently I have discovered a new noise coming from around the front sprocket or the gearbox. It was some kind of klicking noise, mostly noticable at low speed. So I lubed and adjusted the chain, that actually made it worse. Probably because of slightly too much chain tension, so I backed that off a little. The clicking has largely gone but now it's more like a bearing noise and it is most noticable on gearing down.
Any ideas anybody?
