The carbs of the Japanse MIKUNI company are part of the reference class if it comes to the perfect working carburettor.
The high quality tuning carbs give a nice increase in maximum power output as well as spread of power.
The MIKUNI carbs and parts are made of the very tight tolerances of 0.005 mm, one of the reasons why they are so perfect working. For setting up you should take some time, because the MIKUNI carbs are very sensitive for altering the setup. They just work when everything is spot on jetting wise.
As soon as this is the case they run perfect and you don t risk that you ride a carb that is setup perfect only on the main jet and blows your engine as soon as you are running on the idle jet after a good thrashing over the main jet.
