Hello
I would like to tune Mikuni HSR 42 carburettor, especially fuel-air mixture. Of course I can do it by regulating air screw and listening if the idle is regular. But I can use an emission analyzer. The question is what values on the emission analyzer should I obtain for this carburettor to be sure that the air screw is corectly positioned.
