ST4S vibration Recently took delivery of an ST4S after 7 years with one of the first ST2's to come into the country (australia), The bike has a vibration which comes back through the bars which is especially bad at 2700-3500 rpm in 2nd & 3rd gears. more pronounced on deceleration. sounds & feels like a bearing, anyone have a similar issue?? In general there seems to be a high frequency "buzz" throughout the whole rev range. bike was poorly pre delivered (not at all) & came back from its 1000k service with a tight chain which I rode for about 200k's before investigating. their apperars no damage to chain or sprokets/bearings. cheers tebby |
