Chopper, I'm also using K&N's but have #62 main jets and it runs without loading up the plugs. The inside of the pipes are a little sooty but the plugs are always clean. The elevation here is roughly 2300 feet above sea level but at the local drag strip some say the air is more like 4000. My main concern is that the secondaries are not kicken in 100% of the time. Oh whell I guess I'll start save'n up for some Webers.
