I have a 01 Nomad that I purchased last year with about 6K miles. I now have over 10k and love this bike. However, it does have a gear whine that I think is getting worse. It may be that my focus has just increased. It is most noticeable in high gear at 50-60 mph and resembles a rear end noise in a car were the ring and pinion have too much lash. The whine is on load/accel and goes away on cost/decel. I do not know or ride with any other Vulcan riders that I can compare with, so I am hoping some of you my be able to give me your input. As is said, I love my bike but may be heading for a divorce! Any advise would be greatly appreciated. I do have the extended warranty and have had a mechanic test ride my bike last year but he felt it was normal…? Anyone using synthetic? Would this help? Thank you for your responses.
