Hi, 

I recently acquired a 1974 Yamaha AT1 125 enduro. 
I have been looking for recommendations for two stroke oil for the injection pump and oil for the engine/transmission.
Looks like Yama lube 2S is what is suggested for the injection pump.
What oil works best for the engine/transmission?
Also does this model have a wet clutch?


Thanks!

Yes wet clutch.  Book calls for 10w30.  Lots of choices out there, just make sure whatever you choose meets JASO MA requirement.  Yamalube 10w40 or Honda GN4 10w30 will work just fine.

In the Tech Library, you can download the service manual for your model.
