    I've heard they're pretty good as well. WSM makes replacement Banshee cranks, coolheads and other stuff.

    Anything will work well if you properly rebuild the engine.

    I asked the same question and lots of people bashed them as junk, but many people have used them in two stroke watercraft motors for years. I think they have a different clearance spec than Wiseco so I agree about how people set them up. I think they are cast not forged.

    i haven't had much luck with them in my pwc's, but they failed by my error. I've been runnin one in my 4 stroke quad for 2 years though.
    The person who says it cannot be done should not interrupt the person who is doing it.
