MIKUNI JET MKA290 (Manufacturer part number: 4/042-290) — Replacement part from Mikuni designed for carburation interventions. Created for motorcyclists looking to fine-tune the air/fuel mixture, this jet fits into compatible Mikuni carburetors and is used to adjust the fuel flow for a more suitable carburation for the engine and operating conditions.
Ideal for tuning operations, replacements due to wear, or for adjusting the mixture according to altitude, fuel type, or engine modifications. Simple installation for a skilled DIYer, but fine-tuning the carburation requires appropriate tools and method: cleaning the jet seat, checking the fuel filter, and adhering to the torque specifications recommended by the manufacturer are essential.
Practical tips: check compatibility with your carburetor before ordering and keep the manufacturer part number for any future interventions. If in doubt, have your carburation checked and adjusted by a professional to ensure optimal performance and reliability.
