better use TM28-1, easier to rejet, has accel pump, we can easily modify it to use TPS.. TMR-MJN is better but maybe it's a little harder to rejet..

TMR MJN is made by yoshimura

check out the other thread about it here
TMR-MJN carb

also theres an available TMR MJN 28 which is 28mm.
its available in japan for around usd$700

while TMR MJN 24 (24mm) cost around usd$300

as yoshimura is saying, it provides more power
and less fuel due to better atomization of fuel.

on MJN, the fuel is squirt at the center of the carb.
unlike on stock jet needle, fuel squirts at the bottom of the carb.

TPS=Throttle Position Sensor, a potensiometer attached to the catb which tell the CDI about the carb slide position.. the CDI then adjusts its timing accordingly..

bro Yoshimura TMR-MJN is the same as mikuni TM flat slides carb

TM-MJN 24mm = Mikuni TM24
TMR-MJN 28mm = Mikuni TM28-1

their difference is with the Needle Jet.
the rest are stock parts from mikuni
so the pilot jet and main jet is the same with mikuni TM equivalent carbs
