What are the possible problems with over filling your Primary ?

 

Clutch drag & slipping

 

How does it drag and slip at the same time?

 

Did you overfill it, or just asking? You should only fill it to where it touches the bottom of the clutch basket.

 

koots, another problem you will notice is near the front of the primary ... the chain will fling the oil and cause the gasket to weep. It may look like you will need to tighten the allen bolts, but they will be secure....
I thought I added the proper amount, but found the weeping problem, dropped a few ounces out and problem solved.
I did'nt notice any slipage of the clutch

 

The clutch won't slip, it will shudder and not let out or engage smoothly.

Stroker

 

Slip, shudder,chatter, grab,drag...whatever.

 

drain it and refill with a new bottle...cheap enough and no worries

 

Generally speaking, slip is associated with clutch engagement and drag with disengagement but the dynamics are about the same.

 

If you really think that it is overfilled, you can take a rag or good quality paper towel and dip it into the primary oil at the clutch basket. Take it out, squeeze out the oil, and repeat until it is at the correct level.
