Scooterotica

Evening all, Gave the GP a bit of a run at the weekend and when i got home i noticed a dribble of oil running down the side casing. It`s coming from where the clutch arm meets the splined clutch rod. I take it there`s an oil seal there that needs replacing but i can`t remember if you can do it externally or if you need to take the side casing off to access it. Anybody help ?

If memory serves me right, there is an 'O' ring under a shim under the splined top section which can be replaced by just removing the clutch lever.................CAREFUL HERE THAT THE CLUTCH LEVER ROD DOESN'T DROP DOWN INTO THJE CASING (Can't remember if it is retained by a circlip)
