TMR-MJN28 carburetor for CB400FOUR (408cc: 74-77 / 398cc: 76-77) is the product that Yoshimura's technology and care are applied in many parts.
・TMR-MJN (Multiple Jet Nozzle) The carburetor of this CB400FOUR engine is the large diameter Φ28.In addition, the MJN provides the ideal atomized gasoline supply for the severe accelerator work in the extremely low opening range required by large diameter carburetors, and has achieved a setting that is mild, easy to open, and safe to run even with a stock engine. ・Special spigot The Yoshimura TMR-MJN carburetor is designed with a spigot length that allows the carburetor body to be placed as close to the engine as possible in order to shorten the intake pipe length.This CB400FOUR carburetor is also newly designed with very short spigot for better throttle response and higher power output at high rpm. ・Pitch for CB400FOUR This carburetor is specially designed for compact CB400FOUR engine with very narrow carburetor pitch.For this purpose, each existing TMR carburetor is disassembled, checked and adjusted by experienced Yoshimura mechanics, and assembled by hand. ・Body Design TMR's unique round shape of the high performance flat valve racing carburetor does not spoil the atmosphere of the standard CB400FOUR and gives it a casual presence. ・MJN Top Cover (Red) ・Aluminum drain bolt (red) ・Exclusive emblem for Yoshimura TMR-MJN
■Three types of specifications are available ・Dual stack funnel specification The dual stack funnel is Yoshimura's original two-stage structure funnel which is a combination of a short funnel and a long funnel made of machined aluminum, and is characterized by its high intake efficiency in the whole area. ・Funnel specification The optimal length of the machined aluminum funnel is set based on output tests. This is a standard model with a style reminiscent of the racers of yesteryear. ・Stock air cleaner box specification It is possible to install TMR-MJN in the stock air cleaner box.The special black anodized sand casting adapter is designed with a special passage that allows only clean air that has passed through the air cleaner to enter the pilot system passage as well as the main bore.This allows you to experience the high performance of a racing carburetor while reducing the risk of inhaling suspended particles.
It is strongly recommended to replace the stock tank band when installing. Although the stock insulator band can be used, it is recommended to replace it.
