Description

A properly sized main jet is critical to carburetor tuning—too rich and you'll sacrifice fuel economy and throttle response, too lean and you risk engine damage. The MIKUNI #70 main jet delivers the precise fuel metering your carb needs for optimal performance across your RPM range. This 4-pack ensures you have spares on hand for testing different tune scenarios or replacing worn jets in multiple carburetors.

Fitment note: These jets are designed as direct replacements for Mikuni carburetors originally equipped with 4/042 main jets, including VM18 (clamp-on), VM24-512, VM26-512, VM26-606, and TMX Series models. While many OE and aftermarket applications use identical dimensions, verify your carburetor's jet size before ordering to ensure proper fitment.
