Hi
I have an 08 plate F650GS and have an ongoing problem with what seems to be a fork oil seal leak.
I have swapped out the seal [again] and had a good look at the stanchions. There was a very small amount of pitting that I have dressed out.
My query is the fork oil capacity in my Haynes manual is @ 530ml with a 100ml air gap to the top of the stanchion. When I have refilled again today I have used over 600ml [roughly measured by the oil bottle] to achieve the correct air gap.
Would anyone know the correct factory fill levels for these forks - my concern is that an overfill will increase the internal oil pressure and could be the cause of it passing the oil seal?
TIA
