After going through a couple of evenings of hell, I came up with my own nose ring. Since I was dealing with a 2-stroke, I had my own set of problems and the nose ring for a 4-stroke wouldn't fit. Anyway, here are the results.

The two pieces are made from 1/8" fiberglass-covered end-grain balsa, but plywood would work just fine. The bumper is made from a 113mm of medium fuel tubing split lengthwise.

The front of the holder is pushed right up against the front of the air intake hole on the left side. On the right side, it's back 1/8" and the gap is filled with scrap. After smoothing down with a Dremel and some sandpaper, it really doesn't look too bad.

If anyone has scaling problems with the drawings, the nose ring is 2.75x2.1 inches and the holder is 3.8 inches wide.

Excuse the hacked out holes for the screw access. I didn't have a chance to clean it up before I took the picture!
