| My ST4s has over 6,000 on it now and no problems from the clutch. It is heavy, like all of them and a but clattery but no where near as much as my 900ss was, thanks to the alloy plates.
I ran the 900 to 22k on the original plates and only changed them because I was offered a new set at half price. They had plenty of meat left on them but the tangs on the friction plates were well hammered. It is this hammering action which can cause the slots in the basket to become grooved, affecting the release action which can get snatchy.
At 4,500 miles I'd be very ****ed off if the clutch needed replacing. Are they suggesting the complete clutch needs replacing or just the plates? It may be that the basket is grooved or more likely that the clearances between the tangs on the friction plate and the basket have reached the "service limit". The clutch can operate perfectly well with much more clearance but will wear the basket sooner rather than later. |
