Hi, Brudge I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost. If you are a little short on "DRACHMA" and a Dealership is not on your list of fun places to visit then perhaps the list below will help soothe your worried mind so you can make an informed decision.
