Best to use genuine Mikuni jets too.
Kit ones or knock off are prone to be incorrect with sizing whatever the advert states.

By the way, Welcome and the bike is a rally nice example. The mufflers look to be aftermarket, (going off the manufacturing stamp on the rear top). Found a set of those pipes on Fleecebay for a friend 76 and when he put them on he was pleased with the overall performance. Changing the mufflers will take its originality away. They may not be factory but they are original style

Mufflers are signed as OEM Yamaha, just checked.
