Tuning a Mikuni carburetor for maximum performance demands high-quality components, and these EBC hex head main jets deliver exactly that. Manufactured by A-BAX Precision Engineering, these size 380 jets are designed for the 4/042 style main circuit. They are compatible with Mikuni VM, VM-18, VM24-512, VM26-606, and TMX carburetors. In the shop, we rely on these jets for their consistent sizing and durable brass construction, which stands up to repeated removals during the tuning process.
