The pod K&N may be too restrictive at high rpm, because they're too small, especially if over-oiled, which is too easy to do.

Hi that's the settings recommended by Steve Wesson to be used with longer down pipes/no cross-over/lafraconi competion exhausts when I fitted the exhausts.Also the carbs were fitted with lighter and cut down spings in place of the heavy(very)external bell crank springs and seperate throttle cables with  twin pull throttle.Also used S & B filters.With standard points set up would rev to the stop on the tacho(not too often) when the red mist descended !
regards Dave
