Have you done any mods to it? or is it all stock?

Hello,

Your pilot seems a little on the rich side, there is a Air/fuel screw that needs to be drilled out, Main jet also seems a little on the rich side.

These OEM carbs are designed tp run with an air box lid, but can be modified to run without one.

We have already established base line jetting for any engine mod/combos for the Raptor 125.

Thank you,
