    B8ES with the stock resistor caps and BR8ES with non resistor caps, both with the solid tops.

    Bravauto nr4ap should run great and be more fuel efficient than conventional br8es.

    Pretty hard to find though.

    I call BS on fuel efficiency

    My bad, got efficiencies confused with horsepowers.

    Those plugs have a .08 gap with titanium nitrade nikasil tips have been claimed to add 19% horsepower and not efficiency.

    Most efficient setup would be a westcoast dual spark head, (also rare) with e3 pugs on the end of the "r" caps.

    Re: what spark plugs?

    With all due respect, there is no spark plug on earth that can net a 19% power increase (even 1.9% increase would be optimistic). Spark plug gap is a function of how much voltage the ignition has ... it is not a function of plug design. Attempting to run an .080" plug gap on any Kaw PWC will net very poor results.

    Unless otherwise stated, responses to all forum posts are based on my personal experiences working within the PWC industry, and developing high performance PWCs since 1987.

    I'm sorry if this offended you, it must be an inside joke.

    (The joke is "timothy's other posts) in sure you will be able to find the humor. Although, to each their own.
