At the end of the day, there's only two places it can originate from. The 2T reservoir(s) or the transmission... or a family member/friend with a warped sense of humour!
I would've thought it's unlikely that holding the 2T pump pulley wide open for a minute on idle would be enough to create a pool of oil under the bike. Best plan is probably to get in there with carb/brake cleaner and thoroughly clean away any oil residue and start it back up to see if you can trace the culprit.
Hi Andy
I thought I would update you on this now that I have spent some more time on the bike.
I found a snapped exhaust header stud which is causing the oil wetting around the RC valve and there is definitely a leak on the oil pump somewhere (not investigated yet as working on the barrel etc)
So a combination of two issues making the right side of the engine soggy and miserable!
Thanks for your input and effort 👍
