I'm getting close to needing my 6000 mile service and was wondering if much takes place besides for the valve job. What can I expect to pay? My dealer is saying it will be around $500, does that sound reasonable? When I was looking at the Monsters last spring the sales guy told me that a 2 valve adjustment is usually $200 to $300. I'm wondering if they do other things in the 6000 mile service to cover the $200 difference. I also would like to lower my gearing a bit, do people recommend replacing the front or back sprocket and do youthink that I will need a new chain? The bike is a 2000 M750 I bought last June with only 1056 miles on it.
