m3boy - good to know this. The BB has had new synthetic 80/140 gear oil added to it and it is now barely perceptible. My dealer was of the opinion that, even though the manual spec's out the oil as being synthetic 80/140, it clearly wasn't. The belt and the rear sprocket are still doing their thing and making incredible high pitched squeaks now and then depending on throttle or lack of same. At this point I'm leaning on the idea of sound suppression more than anything else as it is clearly not damaging, just annoying. The great majority of the sound is coming through the seat belt access and the gaps from the bodywork and the frame. When I have sufficient down time it will be addressed. It's very much like having that eardrum being drilled by this high pitched whine.


What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
