Includes Main Jets 145-170, Pilot Jet, Dual Needles, Hardware & Instructions, 3x3 Mod & Exhaust Upgrade Ready

【For DR-Z400S / SM Models with Mikuni BSR36 Carburetor】Designed for Suzuki DR-Z400S and DR-Z400SM models equipped with the factory Mikuni BSR36 carburetor. If your DR-Z400E still runs the original Mikuni carb, it will also work. For Keihin FCR39 equipped models, please confirm fitment before ordering.

【Ideal for 3x3 Airbox Mod & Aftermarket Exhaust】If you've done the 3x3 airbox mod or installed an aftermarket exhaust, your engine is running lean. This kit provides the jets and needles needed to restore proper fuel delivery and smooth, responsive power.

【Precision-Machined Brass Jets】Quality brass construction ensures accurate fuel metering and consistent performance. Durable hardware withstands repeated tuning adjustments without rounding or stripping.

【No Permanent Modifications Required】Direct replacement for original Mikuni BSR36 components. Fully reversible installation — ideal for maintenance, performance tuning, or returning to stock settings.
