All info on carb as follows; Keihin 3900B CRG09 FLAT CR

I had to replace this carb because bike would die off idle, or LEAN BOG, as I found the term later.

Also, the last 20 years, the bike would die in deep water, so I got a side benefit by replacing the carb.

The carb is in relatively clean shape, and I was pretty meticulous for keeping the air filter clean, so little to no dirt incursion over the years.

Here's an interesting article I found AFTER I replaced my carb;

Use it for parts, or, maybe you're good enough to tune the problems out of mine.

$400, or non-insulting Best Offer
