  • Custom air filter assembly

    Hello, I’m building an air filter assembly and I’m interested in getting input from the group as to weather what I’m making will cause any problems that I’m unaware of. I ordered a k&n e3514, it’s basically a large oval about 4 inches high. My plan is to build a plate with holes that will accept the stock velocity stacks and a second plate to sandwich the filter between. I’ll use some standoffs between the stacks to hold it all together. It will function like a a single large pod filter but I will still be using the stock stacks.

    I’m curious what this is going to do as far as jetting goes. Is there a reason I haven’t seen anyone els do this. Any input would be greatly appreciated.

    p.s. if this is the wrong forum for this I apologize. for some reason I am unable to post in any forum other than idle talk. I’ve emailed the admins but I’m not sure if it’s just me or if that’s just the way things are as I’m really new here.

    I've seen pictures of an air filter called the Henry Abe bread box on the Kawasaki KZ forums. Sounds like something that you are thinking about fabricating?

      Bderum,
      With all the work your custom filter assy. is going to take, why not just use the stock OEM Filter Box? No need to worry about jetting changes etc.

      I know some prefer the "Look" of the POD style and others just hate wrestling with the OEM box. The OEM box can be a PITA that is true. However, once you get use to the little tricks for getting the carbs in/out it's not really too bad. Also, once the carbs are properly cleaned and set-up well, if the bike is maintained properly and driven somewhat regularly pulling the carbs back out is a pretty darn rare event. I haven't had the carbs out of any of my XS11's in a couple years.

        So I agree with you and I actually sort of like the stock air box and that was my original intention. I promise I didn’t just get a hair up my ass and decide to tear off the old air box. However upon investigating the literal pile of parts that is this bike. I realized that 1. my airbox is missing the center plate, and 2 the jetting installed is actually a stage 3 dynojet kit. I have the stage 2 stuff as well, so I could go to that and use the original box I’d just have to find a new center plate.

        I only started down this path because the PO had pod filters on it when I got it and something inside me doesn’t like those. Probably because I like the word velocity stack and I wanna use them.

        also Ranger_xs1100 is spot on that’s exactly what I’m building. Any reason why that wouldn’t work. I guess we will find out either way.

          All I can think of is keep room so you have about 1 1/2" between the stack and the back of the box. There is also the crankcase breather, it will need a filter or to be placed into the airbox like stock. I do have a few parts here, let me know and you can have them for shipping cost. PM me and tell me what you do have, or send a pic, and I'll try to fill in the blanks for you.

            I am trying to understand what you mean by missing the center plate.

              I’m just using the wrong name for the piece, I apologize I should have looked it up. It’s item number 14 in this pic.

                  lol thanks Andreas. I know you’ve contacted me and I promise if I end up wanting parts I will contact you to see if you’ve got what I’m looking for. This bike was an actual pile of parts when I got it so anything I do at this point is an improvement if it moves it towards being on the road again. Also the the air box build it partially because the PO had the jetting set up for a 4-1 with aftermarket filtration IE dynojet stage 3, and since I don’t like pods so much I’m making a different option. If it looks like dog **** or doesn’t work well I’ll scrap the idea and use the stock airbox.
