I have a
kymco 50cc
2t 2 stroke
Stock carb 110 jet
4.5 horsepower stock with 75 jet
I have pilot jet 35 stock is 22
It runs 50mph stock ... no mods
Aftermarket short filter
Modded oil injector
Modded spark plug spacer
And modded spark plug gap
I run ..02 mm gap per 20jet increase
And .1 mm spark plug spacer
I run a performance accell noise suppresion spark plug wire,
I run idle rpm 500 to 700
1.5 inch exhaust
I run custom fuel screw air screw setting
Based on the filter
I run no front air jet
because of the size of the needle fitting.
I pull the whole front air jet out
I run a custom needle spacer
It would be just below the halfway space
I run its settings rich because the carb is small...
And the air filter is almost free flowing
Tons of r very lite fuel with a stock carb
