  • Ported Manifold

    I was wondering how to acquire one of those famous ported manifolds for my bike...

    Curt is the man on here, if he's still doing them. I saw a few Baron's on Ebay, although reputedly not as good as Curt's, however, that could be RSC bias talking

      Curt is not doing them anymore. I saw a pic of a Baron's ported one and it was barely touched. Curts were full on ported and looked beautiful. Glad I got mine before he quit making them.

        If you have a dremel with a flex shaft you could do your own up pretty well, there is a LOT of material in the corners to remove. I was shocked at the difference.

          Which one you looking for? 1600cc or 1700cc they are different.

            Buy what ever is the cheapest new manifold, then port it yourself. I bought a Barons "PORTED" (that's a joke...see below before and after) and ported it myself. The advertisements stating that the Barons ported manifold is a bolt on 6-8 horsepower is total nonsense.

            Hit it with a dremel or air tool to take off the bulk of the rubber, then take a 10-12" long piece of fabric sandpaper (I think it was 200 grit from Harbor Freight) and clamp the manifold into your bench vice and roll the sandpaper the size of a cigar so you can put it in the carb side and into one of the cylinder ports...just pull back and forth and it will take off the rough edges. Worked great.

              Be sure and surface the flanges that mate with the heads, also. It doesn’t take much. A few figure 8 passes on a piece of 300 or 400 grit abrasive paper laid on a hard flat surface, will get it done. That was something Curt did as part of his porting.
              Curt would also solder the vacuum port shut on the manifold for those that wanted it done. It ends any problems with a leak developing later from a cracked or missing rubber cap or plugged hose. Some members cap it, so they can use the port to check manifold vacuum.

                Ported mine myself with Dremel. Very easy to do just takes some time.

                  Soldering is a great idea to make it permanent....but doesn't heat during soldering create issues? Seems like the nipple would get very hot and screw up the manifolds rubber?

                    No, it really doesn't get it THAT hot, and if it were a problem it would have been noticed.

                  I did my own myself as well. One afternoon and it was a fun project. Noticeable seat of the pants difference.

                    Where do you feel the difference? In the throttle response?

                      It lets more air in. It's felt across the power band. Stepping to a hsr42 is what'll be felt strictly in throttle response. The 42 won't necessarily increase your power though since the stock carb jetted correctly with the proper filter element flows more than enough air for a stock motor to use.

                    Especially if you bolt a HSR42 to it ...lol

                      Got my HSR42, jets and needles to bolt up after my paint is done So looking forward to the better throttle response!

                            I have been looking at those same bags for a while. Really helps to see them mounted on the bike! Wonder if they will clear the tour trunk I have mounted

                              So i guess I should buy a barons ported and re-port it myself? I cant seem to find any stock manifolds for sale. BTW mine is a 2000 1600 silverado.

                                Why pay the extra money for a Barons? Just buy a stock one and port that

                                Ditto...do it yourself. You will lose a little of that off-idle "grunt", but the mid-range & upper-end is awesome.
