Default SERT or stage 1 for rocker
why is the SERT so much beter.. stealer says popping is possible with the stage 1 because of the big radius.. i plan on using the heavy breather. all rockers running strong with this set up?

Stage one normally includes some type of EFI adjustment.

Greetings,

I have the Screaming Eagle air cleaner, Stage 1 download and V&H Short Shot Staggereds. There's no popping or issues at all. It runs strong and has a lot of torque.

Once your engine is breathing it's going to need to do a better job at providing a stable fuel mixture. Your carburetor or EFI will need to be corrected to compensate for how differently the engine now breaths. Fuel injected models use a preprogrammed map to instruct how much fuel is to be delivered. Since you have changed the way the engine breaths, those instructions may not supply the proper stable fuel mixture under all conditions. Granted your bike will still run, but the only way you are going to get the most out of your EFI bike is to have it remapped.

If you don't adjust the fuel / air mixture, if the bike runs rich, you'll just foul plugs if it runs lean you will damage the engine.
