Default jammin 21

+1 no shims needed for 30%, unless you like your motors slower than they should be

I had some detonation on my first JPX running 30% without adding a shim. I added a thin shim to that one and a new JPX. They both run like a scalded dog. So I would say maybe add the shim if you want to be on the safe side. I do not think you will lose any performance.

The most important thing I have seen with these engines is the carbs have to be sealed where the aluminum and plastic meet. I also seal the pinch bolt and the banjo fitting.

its not worth the hassles to run anything but genuine Picco plugs....some other plugs may work, but nothing fits and works as nice as the plugs designed for the engine...
