I was using a K and N filter with no airbox,and im putting my airbox back on,and ill be using the box lid too.My jetting was 260 main-37.5 pilot,i know i need to use smaller jet sizes now,could someone give me an idea on where to start?

 

please help me!

 

I have a 87 quadracer and run a 35 pilot, and a 280 on the main it runs pretty strong.But it depends on your reed set up.I have g3 power curve reeds,and they are 10 pedals so they suck alot of air.But anyway this sould give you an idea were to be.Just drop down in your pilot jet.
