    Berryman's B-12 Chemtool (2 questions)

    I've used Berryman B-12 Chemtool for cleaning carbs, crankcases, pcv valves and everything that isn't painted for 35+ years, unless of course I wanted to remove paint.
    I've even put it in crankcases just before oil changes and gas tanks to clean varnish for periodoic maintenance. It's amazing stuff!
    Question #1: has any one else used it?
    Question #2: how would it work in an ultra sonic cleaner as a solution?

    Yamaha carb dip would be a better option I think.

      I use it exclusively but I dont have an ultrasonic. I agree its amazing stuff. I throw half a can in the tank of a bike I take out of storage just to refresh the carbs after a restpit. Yes I drain the bowls and do the storage as the manual outlines but I see no harm in a good dose of Berrymans in the first tank of gas.

      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        Never, ever use anything flammable in a ultrasonic cleaner. They're designed to work with water based solutions only.

          Thanks guys, I guess the flammability was my real question. It does well just sitting too.
          Ed, I've used Yamalube two stroke oil before, didn't know they had a variety of products, thanks.
