I picked up a performance L28 recently and these SK tripples came with it, wondering if anyone can tell me about them, there is not much about them in the archives.

I removed the cover for the jets and there are four jets just like webers, the two at the back on the emulsion tubes are 120, the two at the front are 60F8. The other two carbs are the same.

Thanks,

Those are Weber jet numbers. Probably copies...

Look like OER's to me. Note the Type "OER 40".

They are junk... I'll take them off your hands for a set of rebuilt su's

Correct.

FWIW, OER uses Weber jets.

Speaking of interchangeable parts: Do Dellortos and Webers share the same chokes? (I know that SK and Weber do).

Not sure about that Blue... Dellorto carbs have had a transition circuit in my experience that made them 'an improvement' over the Weber they copied... Probably?

I am going off of vague recollection here, but didn't SKs take Mikuni pilot jets and Weber mains and airs and emulsion tubes?
