| 14T sprocket ST4S ?
Has anyone fitted a 14T sprocket (ST4S '03) - i've done this based on items i've read here and other sites, the problem is that i get a sort of 'droning' noise when coasting (clutch-in, tickover) which comes in at about 30mph as the speed drops but disappears below about 20mph.
I've tried alternate chain tension etc. etc. but can't get rid of it. obviously i've re-fitted the 15T standard and it's then o.k. - is this perhaps the chain rubbing on the plastic guide on top of the swing arm since with the 14T the radius is smaller so brings the chain nearer the swing arm (i'm assumming this 'cos in the condition described, the top of the chain is the slack side).
Any help / suggestions greatly appreciated.
