The RA needle is a little leaner at idle and a little richer overall than
the stock N-17. The RA should work fine. The exact needle that works best is
very dependant on everything that has been done to the engine, cam, exhaust,
intake, ignition, etc. The RA is in the small group of needles that are in the
ballpark for the U20.
