Re: Ringing/tinkling noise
i had this problem on my last 75, a twinnie.
drove me mental for weeks and i feared the worst ! to cut a long story short, someone had dropped a washer down the exhaust, which had fallen into one of the boxes !
you don't say what area the noise is coming from ? does it only happen under load, or is it there if the enging is revved in neutral ?
it's hard to diagnose a sound without hearing it, but it's worth having a look at the exhaust, maybe a box is collapsing, or a heatshield is loose ?
i had a clicking noise when my centre donut was breaking up, but it was more speed related than rev related ?
also have a look at the blades on the alternator fan, make sure they're not obstructed, or bent ?
you're never alone with schizophrenia.
