Oiltek recommend 85WT in LTH clutches.

ST90 was great back in the 60's 70' maybe even 80's to. There are far better oils to use these days especially when using in tuned engines or with cassette type clutches etc.
I run a tuned ts1 230 with an AF cassette and found i got slip when i used ST90. I swapped to motul 2t 10/30 transoil and havent had a problem since.
