PX200E Lusso running too lean after air filter upgrade – already went +8 on main jet?!
Hey Vespa community,
I ride a Vespa PX200E Lusso and recently switched to an air filter with the hole above the main jet.
Since then, the scooter is running way too lean (spark plug is very light/white).
I already increased the main jet by 8 sizes, but the issue is still there.
Honestly, this doesn’t seem normal to me.
Does anyone know what could be causing this?
Or would it be better to just go back to the original air filter without the hole?
