I am using 10 w 30 full synthetic motor oil. It's winter here in New York need light oil.
The fiber plates and steel plates look good and are properly installed.
Anybody here ever have clutch slip problems?
I'm just trying to cover all the basis before I start changing out parts.

Does the slipping mostly happen on hills?
Does it happen under hard acceleration?
Clutches can wear smooth from using the clutch a lot. Apparently this happens a lot on dirt bikes. There are a couple of fixes you can try.
Check this out before you get all bent out of shape about your oil.

It worked for me.
Also check that your clutch plates are flat.
My wifes GZ250 has Mobil1 (Gold Cap) complete with friction modifiers and has been using it for nearly 6,000 miles. It doesn't slip at all. Ever.
