New old stock #54 jet for batavus moped. 15.8mm long 4.5mm thick and 3mm thread. These were picked up from a dealer buyout and were mixed in with Jawa, Batavus, Trac, Safari, Solex and Cimatti Moped parts. So they may be able to work with other carbs. Check measurements first. Great shape and ready to ship as is.
