When I rotate the rear wheel there's a noise like rubber rubbing on something. Does it in both directions but NOT when the bike's cold.
I've not had a good look at it yet but does anyone have any ideas?
Thanks.
PS Changed the oil on Sunday - she feels like a new bike now!
PPS Rear light fuse blew again - that'll teach me for posting "it's been OK for a few days"!

 

Dust seal/cap for the wheel bearings I bet.

 

Or the cushion rubbers in the sprocket carrier??

Worth a look if the tyre is not rubbing on anything.

Cheers, SB

PS: beat me by microsecond Sprock!

 

Thanks Con, the old dust seal was mis-shapen and bloated (like my stomach). Fitted a new one, the squeaking has stopped!

Have just changed the oil and fitted new DPR9EA9 plugs. The old ones were in good shape, nice grey-brown and not fouled. But after fitting the new ones, the engine was revving 200 rpm higher than before (so I turned it down a bit). This coincided with sudden cold weather.

Are the two connected?

Thanks.
