    Do carb outerwears cost performance?

    Making the switch to Riva flame arresters, with outerwears for water protection, I wondered if anyone has tested for any significant performance difference between with them on or off?

    Some say 30-50 rpm.
    I haven't done a test, but I personally keep them on my ski. It has saved my butt a couple of times in the past.
