Hi, Anonymous 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.
3. Brake Rotors---BUZZ
6. Shifting Trans---CLUNK
7. Front Forks---PLUNK
8. Rear Shocks---SQUEAK
10. Solid Lifters---TICK
11. Hydraulic Lifters---TAP
13. Connecting Rods Go---KNOCK-KNOCK---who's there, it's me "*****"
