Agree totally, though not sure you need a Dremel - on my 4s I've always been able to get the endless chain on and off by just removing hangers and guards. I usually replace the front sprocket at about 10,000 miles (a 15 minute job), then both sprockets and chain when the chain gets tight spotted - usually about 10,000 miles later. I suspect I get better chain wear by earlier replacement of the front sprocket as it wears appreciably quicker than the rear (hardly surprising I guess as each tooth does much more work). But once a chain starts to go, you're on borrowed time, and the consequences of it snapping can be pretty catastrophic. Also, when replacing the chain, be very careful not to over-tighten it - a properly adjusted chain can look too loose to a non-Ducati mechanic, but too tight can also lead to catastrophic gearbox bearing consequences, in quite a short period of time (don't ask...)
Unless you've also done so, you probably need to get ready for new clutch friction plates, more than 20,000 miles on a set is good going. In my experience you can usually get away with just replacing the plates rather than the whole clutch basket if you don't mind the rattle. Yes the edges of the basket will have been a bit bashed by the tangs on the old plates, but it doesn't seem to noticeably affect the clutch operation, and plate replacement is also pretty straightforward - one advantage of a dry clutch.

See the face, admire the bikes, yawn at the holiday snaps... http://www.worldwidewobble.comOn 01/07/2013 7:09 PM, Jack wrote:
As someone mentioned earlier, you are playing with fire by leaving it on the bike. 18,000 miles is pretty decent chain life. I'd replace the chain and sprockets, if I were you. I sometimes get 20K, on the bikes I ride most, but leaving it for a single winter (or any significant period of time) is enough to cause the problem you have. Replacing the bearing in the case that it may destroy, you don't want to think about. If you have a chain tool, hand tools and a Dremel, a chain and both sprockets will cost just a bit above $200 and a couple of hours of your time. Don't know what it costs to have it done professionally - I've never done that.

Thanks for all the great info. Based on your advice I will thoroughly clean the chain, re-grease, and see what I have. I have 18,000 miles on this chain so I should prepare for the worst.
