Carburator -MIKUNI 30mm TMX30- manual choke, Powerjet - CS=36mm

The carburettors from the Japanese manufacturer Mikuni are in the reference class when it comes to perfect tunability and thus the highest achievable performance with optimum consumption. Mikuni carburettors and parts are manufactured with tolerances of 5/1000ths. This is one of the reasons why they run so perfectly. However, you should take a little time for tuning, because Mikuni carburettors do not run with any carburettor equipment, but only with the really suitable one. But they run perfectly and you don't expose the engine to the risk that it only runs cleverly in some partial load ranges and then goes up in one of the other partial load ranges.

The TMX 30 also offers the possibility to tune the carburettor leaner in the medium speed and slide range with the Powerjet nozzle to gain power and reduce consumption. In order to avoid a lean tuning in the upper slide and speed range, the Powerjet nozzle is used there which, due to the high negative pressure at full throttle and high speeds, additionally feeds petrol into the intake flow.

The Mikuni carburettors react quickly to fine contamination of the fuel by overflowing the float chamber. Therefore, ideally use a good fuel filter.

The standard Mikuni TM30 is quite good in most cases, but on automatic engines the side jet should be located in the range 15-17.5.
