    Yeah the white brothers E series are similar to supertrapp. The discs are probably the same also. I got the PC off ebay for $40.00. It was for a 400ex and I modified it to fit my 200x. Sounds really nice on there and is holding up great, I just need to find a way to seal the inlet up a little more.

    i would tie it up to the frame but that wouldnt look nice lol. what kind of modifications does it take to fit it on there?!! i want one very bad now lol. what other silencers would fit on there, my cousin has a 400ex silencer on it but im still wondering what he did to fit it.

    Cut the header shorter, make a hanger, and make a coupling that adapts the 400ex inlet to the header. The 400ex inlet is really big and will not just slide onto the header. I had to sacrifice a old junk cobra and cut that inlet and a little bit up the cone to jam into the inlet and weld it in. Then it just slid on, but I had to make a 1.5'' hanger to attach it to the frame.

    after exhaust and carb jetting if you still want more power, try polishing out the ports... I wouldn't recommend grinding on your engine, but you would be supprised what just some steel wool and polishing compound can do. I did some work on a 3.5hp briggs and stratton flathead and it's amazing how much more power it has.
    When in doubt, Gun it.

    Mothers is a polishing compound. You can buy it at walmart, napa, autozone. Pretty much anywhere. Ive even seen it in grocery stores.

    Can you really polish intake runners with car body polish (Mothers)?! I thought maybe you needed to smooth the runners first...
    I'm back in the USSR...

    I dont know a whole lot about port and polishing. But he said smooth it with steel wool first. Mothers does make it really smooth though but im not really sure though.

    With the steel wool and polishing compound it's really cheap and easy, But it's time consuming... On my little 3.5 horse I spent about 2 hours per port.
    it would be like twice that for a 200x.

    to speed it up a little you can take a normal cordless drill put a bolt in it spin the drill while holding the wool against the bolt (works best on about a 12mm bolt head) and let the wool spin into a ball on the end.

    Then just start smoothening out the ports with it... after you get it down were it's all smooth just take a normal shop rag and some polishing compound (not the wax type) and rub it on the inside of the ports... it gets them real shiny and smooth after a while... but it gets boring... I brought my block into my room, put it on a towel and polished it while I was watching a movie...



    Here's a link for the polishing compound. It comes with a mini powerball, that will really speed up the polishing time.
