About Yoshimura Carburetors

MJN Carburetor / Theory is simple!

• MJN system can atomize fuel much better than ordinary solid type needles.
• It is because MJN nozzle controls the amount of fuel in proportion to the throttle opening (the air), by numbers of accurately drilled small holes.
• Better atomized fuel gives better throttle response as well as better fuel efficiencies.
• MJN system can supply the fuel through the MJN nozzle which locates at the center of the bore where air speed is the fastest. This also atomizes fuel even better! Another very important theory of MJN system is when the throttle is shut off for engine braking, very minimal amount of fuel is guided into the intake ports. Therefore remarkable recovering acceleration can be obtained.
