    Does it sound loud as all get out, or can you hear yourself think next to it?

    I actually had a straight pipe as in no baffle 4-1 on Banshee once. Ran ok, but woke the dead when I was getting in the throttle at all.

      I'm pretty sure if i pinned it you could here it in Cincinnati.

        Sounds like you have no baffles then. With those pipes you may be able to find a Supertrapp baffle that will go in that pipe and do fine. Otherwise, you may want to look on fleabay for a decent exhaust, there is a Kerker on there now.

            Another option, one I am keeping an eye out for, is the stock Hardley mufflers. 95% or more of Harley buyers immediately scrap the stock pipes and through on some V&H or Screamin Eagles that sound about like straight pipes. Louder = better for that crowd in general. So they really devalue the stock mufflers, which fit and work well on our bikes.

              It's not just about loud, well it is for some owners, but Harley really chokes their bikes as delivered. A simple exhaust change, better air cleaner and re-jet is worth a documented 20% more power on nearly any of their bikes. That's a bit less true now with their EFI bikes, but that's still a big reason there's a zillion choices in Harley exhausts....

                  Whats interesting about that Steve, is your one of very few Harley owners I have met to date who know anything about that. Most just know it is much cooler, or the dealer recommended the swap.

                    Yeah, sad isn't it? I'm not one who particularly cares for loud bikes (I like the quiet stock exhaust on the XS), but if you want to make any serious power with a Harley, that's what it takes. But few HD owners select on the basis of power gains or losses, most just want the 'sound' or a style, so many don't even see any gain except in racket. Loud pipes by themselves don't offer anything (and sometimes hurt the low end), you need to open up the intake too and rejet.

                    There's probably only a few dozen aftermarket systems (for all the models HD sells) out there that are actually primarily designed for power increases, most are simply loud and sold on style. Some of the crap that is sold to those guys flat-out amazes me....

                      Well, I've been busy for a while. Hurry up and wait type stuff. Finally got all the pieces for the carbs I need and I will get my tank back from being dipped and relined in a day or so so it's time to start putting the carbs back together. I'm excited to have the bike functional again but I need to be able to sync the carbs and set float heights. (which I gather, is probably why I was having the fuel leaking into my crank case) I don't have the tools or know-how to do either. Suggestions?

                          Waiting is half the battle. Once you have done it once you know what to look for and order it all at the same time so you can do it all at once. As far as setting the float height. Turn the carbs upside down and get yourself a nice micrometer. They aren't spendy at all. I bought one for maybe five bucks. Set the micrometer at the height you want all your floats. Then with the gaskets off, bend the tab in the middle up or down to set each height of the float. If they are wayyy outa wack. Push the high one down and pull the low one up gently so you don't snap the float. Then try to set each float (right and left) to the same consistent height using the tab in the middle and a tiny screw driver. You will know which way to bend after the first one. It goes relatively quickly after you get the hang of it. Then with a bread tie...pull of the paper and use the wire to bench sync the carbs. Put the bread tie wire in the butterfly and adjust the sync screw till you get a little bit of resistance on the wire and move to each carb repeating the process. The #3 carb is adjusted by the main idle screw either at the top on early carbs (78-79) or on the bottom on late model carbs (80-81). Once you have each butterfly set to the bread tie wire your carbs will be relatively in sync(It will run OK with them bench sync'd). You can either by a sync tool (I bought a SyncPro off ebay for about $70-80) OR you can take them to a shop and have them sync'd to the bike while they are on for about the same price. The tool can be used later so it is probably the best option. A lot of Guru's will tell you to do the leak test while the carbs are off to make sure you don't have to remove them again. And check the float height with a make-shift apparatus of tubes and T's. There are threads discussing and showing how to do each. Just search for checking float height while carbs are off. Both are done with the gas lines hooked up and don't take long although I did neither. The more important one however is the float height check. You want them all the same.

                          Glad you are still making progress, mines running pretty dam good right now aside from an occasional slip in 2nd at really high RPM's. Good luck on rebuilding and getting her running. They are super fun to ride when running correctly!

                            Okay thanks Brown. And when i put these carbs back together do i need some sort of gasket sealer for my new float bowl gaskets? if so what kind should i get?

                                What about all the rest of the pieces should i be lubing them up with anything or just put it all back together dry?
