Fuel n Air Ratio

[Blackenese]

Can Fuel Air Ratio be tuned yourself?

 

 

Where is it located? near to which part of the bike and how does it look like?

bro, first read up on the whole motorcycle engine systems first. that'll give u a rough idea of where u can adjust ur air-fuel ratio. Stoichiometric ratio is 14.7:1, but then again for most power, ratio is different, most economic, also different, different bikes/engines have different requirements. It also depends if u are using a carburetor or EFI system. For a carburetor, u adjust ur afr(air-fuel ratio) using the air screw, main jet, pilot jet, needle jet, carb needle, needle circlip. For EFI, u jz have to fix a Power Commander module or any other ECU upgrades/piggy-backs to alter the AFR.
