Carburetor from a 1980 Suzuki PE400 (drop down menu for year wouldn't go lower than 1981). Haven't had it apart, but probably needs rebuilt. Slide won't move up/down and probably needs to be replaced - bottom edges of slide are bent (probably where somebody took a screwdriver & tried to get it to move up). Needle is missing also. I'm sure Suzuki used this carburetor for more than 1 bike - a good chance it came on the PE250 also - but please double check for anything other than a PE400. Also if you need this for something other than a PE 400, I assume jetting changes would be required.
