My husband recently purchased me a 1984 VT500 Ascot. It is AMAZING! Perfect for me. However there is one issue that I donĀ“t even know how to address. When it is cold out or just cold running the tachometer (well up in that area) squeals with the most horrible squeal. Sounds like a pack of kittens screaming at the same time. Any suggestions? I will say that when it is doing it I can put pressure on the tachometer and it muffles it .... some. Yester day when riding the weather was warm and it barely made a squeal. HELP
