If it's motorcycle oil it should be fine whether semi or full synthetic, it's most likely a free play issue. I had the same issue early on so I wound the adjuster until there was obviously way to much freeplay and took it for a short ride and loaded it up - no slip. Then just a matter of adjusting it back. Only use it as a diagnosing method as leaving it with too much freeplay will cause it's own problems as well. I've never had a bike where the freeplay adjustment on the clutch is so critical to correct operation...
Posted same time as idk - I agree.

1. The clutch MUST be adjusted EXACTLY as per the manual, which you can find in my signature, or you will have problems.

2. If someone put car oil in, even Mobil 1 full synthetic, then you may get a slipping clutch. You MUST use the correct specification motorcycle oil.

Didn't Triumph recommend Mobil1? Or do you mean a motorcycle specific Mobil1??

Yes in the begining the recommended mobile 1 15W50 4t with a secondary being 10W40 . Now days its getting confusing as I see Ames oil is now making a fully synthetic 15W50 although they do not specify the 4t designation. Myself I use Red Line 20W50 4t and incidently the do make a 10w30 and 10w40 both with the 4t designation. But mine takes 50 weight as the originally designed. The winter weight does not matter to me because if I'm riding in the winter its down south and warm.
