Description
The Mikuni Hex Main Jets 165 are carburetor fuel jets sized at 165 and sold as a 4-pack, making the Mikuni hex main jets 165 4-pack carburetor tuning solution the right call for any rider pushing serious fuel flow demands on a Mikuni-carbureted machine. That 165 sizing sits at the high end of the main jet range, so it’s the go-to when you’ve already bolted on a big-bore kit, a free-flowing exhaust, or an aggressive intake and you need fuel delivery to keep up.

Four jets per pack means you won’t kill a tuning session just because you need to step up or down one size.
