I used a thin piece of sheet metal and traced the the casing of the throttle housing, the start/stop housing the throttle housing are identical, just mirror imaged of each other. It was steel that I painted black, but the paint is starting to chip and rust so I have some thicker plastic that I'm going to cut and cap the housings with. The handlebars are from a cr-80. I think there about 26" wide if I remember correctly, or maybe they were 32". It was one of those 2. They seem to fit nicely. Not too wide and I like the look. I put a new handlebar pad that's white and green, matches the look of the skis colors a bit better now.
