I've been riding a 1981 KZ550 LTD since last summer and it's been a blast. It has just under 10K. All is well, except for a noisy clutch basket. My mechanic explained that it will not affect reliability and that new parts would be about $300 and about a half hour to install. I've seen used baskets on e-bay go anywhere from 30 to 80 bucks. Any comments?
