  1. Scott Pieper (verified owner)

    I installed one of these on my 90 radial.
    It is the bomb, made it run smoother, idle slower, and run stronger throughout all rpm range. The acceleration from low to high now has no hesitation at all.
    This is the best upgrade a person should do to this engine.
