I have an odd one. I've had the bike on a paddock stand and the garage floor was clean. Put it on the side stand, started leaking. Put it back on paddock stand, all good.Before I get in there and clean it all up I wondered if there was a known weakness somewhere anyone is aware of. If I didn't know better I'd say it was an overflow thing but there isn't enough oil in it for that.It's not a pressure thing either, leaks whatever temp.

All very vague I know but hey

Clutch pushrod, gearchange shaft or output shaft oil seal.

Thanks, I've taken the cover & sprocket off so I can look properly. It seems to be coming from the gear selector sensor, well at least there is oil behind there. Anybody any experience of this? Next steps?

Look at the parts fiche...if there is an o ring..get one and swap it over...
the seals will be 25 is years old..
