82 250r help (can you identify this intake and what carb it's for)

[madmass]

I finally got a gen1 250r. The guy I got it from had not ran it for 20+ years and can't remember what carb he was running. It has been bored out, don't see much in the porting area, and stock exhaust. This is my first air cooler so I'm a little in the dark.
