This product comes with four Mikuni Large Round Main Jets in the #92.5 size, providing multiple options for tuning or spares for future use.
Will these jets fit my Harley-Davidson carburetor?
These Mikuni jets are designed for Harley-Davidson and Indian Motorcycle models equipped with Mikuni carburetors that use large round main jets. Always verify your carburetor brand and type before purchasing, as Harley-Davidson also used Keihin and S&S carbs.
