Just bought a 03 954RR with 20,000 miles. Bike runs and rides fairly nice for something of its age. I was just looking for any advice on what I should inspect and check out on the model to give it every chance of living for another decade or so. Has a semi rough idle but from what I have read it jumping from 1100 to 1400 is normal. Also it has a buzz at 4000rpm no matter which gear. Buzz very noticeable in 2nd since there is very little wind noise.
