Mikuni carburettor ….unfortunately I do not know what this is from , It is very similar to some early 1980s RM80 KX80 and KE175D but the spec of the nozzle , jets etc do not tally with these bikes and has a cable type choke plunger but this could have been easily changed ,

Intake engine side measures 26.5mm on a manual vernier ,

Body is stamped 293 over 31 and on other side a faint F8 ? ,

Needle = 5D41 , Slide = 2.0 , Nozzle = 277 P-6 , Main jet = 145 , Pilot jet = 25 ,

There is no choke apart from a cable type plunger which is in the recess and is moving freely ,

Overall excellent used condition with nothing broken or seized ,

Please study all pictures to be sure this is what you require , If you know for sure what this is from I would love to know ,

Feel free to message me for any more information ,
