Hey guys, just picked up a weird looking 3 wheeler that turns out to be a "Nicholson 500" or "500x" pretty cool. I can't find what carburetor rebuild kit I need. Its a PE10AARB keihin carb 36mm. Does anyone else have one of these? Are they rare? Thinking about restoring it to be really nice. It has an xr500 engine if that helps. Thanks! I'll post pictures when I can if needed.
