Hi, I noticed an oil leak only when the bike was running. I think it's coming from the cover where the start connects to the engine.
I've had a look at the O-ring and it appears to be fine but I've ordered a replacement anyway (2mm Section 76mm Bore NITRILE 70 Rubber O-Rings from Simply Bearings) to be on the safe side.
Has anyone had anything similar happen?
Anywhere else I should be looking?
Also, does anyone have an exploded view of how I put the cogs back together. I might have.... put them down.... in no specific order...
