soz its been a while,no internet at my place apart from phone...!!!Don't know if clutch has been replaced, only had the bike 4 months and 6 previous owners...!!! bike goes fine apart from very low down revs which i think is caused by after market exhaust(very low sound and loud)bogs down. i think you may be right about the clutch although it performs ok,no slippin or anything else. Its just that grinding noise,but what causes it? thanks $teve
