Hey i today I went for a little blast and noticed and strange whining noise coming from the front sprocket area that changes in pitch with speed , I can hear it above 40 onwards , do I need to worry or could this just be worn chain and sprockets ? Chain looks fine because i clean and oil regularly.Worried about a gearbox issue but the noise stays the same with clutch in or out
i say clicking but what i really mean is an unnerving clunking and as the last chain flung its link i am not taking that risk again as i was only doing about 20 at that time but 5 mins earlier was racing a mate at 110+ (close call much)
Have you touched the rear wheel recently at all, as in done any work whatsoever?And, yes, you need to worry right now, 'cos it ain't normal, if it wasn't there before then something is certainly not right!

This can cause friction on the plastic chain guide causing a buzzing noise until it beds in again, it will go away after a while.

The sounds doesn't seem that far back though, seems to come from right behind sprocket cover, I'll check out the guide tomorrow when I have another listen , I'll put the bike on centre stand with my small bike jack supporting the rear from bouncing and wind it up so you guys can hear it
ok so i got my new chain on today and i had the wine coming from the front as it had before but still the clicking at the back aswellturns out the chain was fine and the sprocket carrier bearing had absolutly shit the bedDetailsthe seals had gone and it filled with shite
