Dear all, Question related to Kwak GPz305. I have a little (not smooth) movement between the crank-driven big gear behind the clutch and the outer (larger) part of the clutch itself. These two parts have been tight in other bikes I have looked at. Sorry, that's a terrible pair of sentences. This has nothing to do with the clutch plates (they have been taken out). I wonder if there's some sort of damping mechanism responsible here, or if the clutch is simply loose. To know for sure, I'll have to build myself a clutch extractor tool and take the inner part of the clutch out, but I just wondered if anyone knows about such a damping system fitted to this model of bike? Or whether something is just loose. Thanks for any help you can offer. Adam
