Yep, I only dry lube the chain with white teflon.. Nothing to collect or fling off.
The Yamalube is purple, so is the residue that weeps from the air screw area. I thought it was coming from the air boot, but that is not the case. It almost appeared as if the float bowl gasket was bad because the oil/fuel residue ran along the seam between the body and the bowl. Most of it collects in the pocket under and next to the air screw.
I can't believe Keihin doesn't install a stupid little washer and o-ring to keep things from gooping up. Whats next, will carbs come without jets or needles?
I will test run after it stops raining.
