  • Stock airbox

    First, let me say that I've had several xs11s over the years, and they all had Pod filters, no filters, or some combination thereof. I always liked the looks of the stock airbox, but just never had one to put on. Now that I finally got my 79 XS special figured out (and d*mn, I forgot just how powerful a smooth running 1100 is)
    I thought it'd be nice to get an airbox, because I like the look. I was in a junkyard here in Sun Valley, and found a 78 XS Standard with a primo airbox, all the hoses and fittings, a good Uni filter, and for $8.95, how could I go wrong? (btw, it's still got the gauges, turn signals, front tire, motor, tank, what looks like the stock Standard exhaust... 2 cylinders into one pipe on each side. and seat, it's in U Pick Parts in Sun Valley, if you're close, call me at 818 481-8952 and I'll be happy to tell you how to get there) Got the pieces, brought them home, and proceeded to put them on my bike. Well, now I know why all the others, including the one I have now, had pod filters. All I can say is, if anyone has a connection to Yamaha, and can get me the address of the sadistic SOB who designed this f'ing thing, I'd like to pay him a visit. It's a good thing the stock airbox looks so damn good, or someone woulda killed that sumbitch. Glad I paid attention when I took it off the bike in the boneyard, and saved all the bolts, or I'da been throwing rocks at something. It's gotta take less than the 2 something hours I spent putting it on, I hope, or no one would keep one of these after they took it off.

    Anyway, it sure looks better, but gawd.... just wanted to vent. Is there some trick to taking this silly *ss thing on and off?

    Oh, and btw, where the ***@@*I* is the turn signal blinker supposed to be on a Special? I've got the parts Standard here, and the blinker is right over the battery under the seat, mine's had the wiring butchered, the PO put automotive fuses (tube fuses spliced in) in place of the stock fuse block, so there's a rats nest of wires under the seat, but no blinker. The turn signals don't come on at all, I know there's gotta be a blinker somewhere. Anyone have a wiring diagram?

    Air Boxes are FUN!

    The top has to be on (loose) before the carbs go in.
    Remove the battery before removing or installing the carburetors. This allows more room to move stuff around. Loosen the top vee-bracket screws to gain some slop.
    I put the carbs on the intakes, unclamped, attach the airbox, get all the bolts started, clamp up all the rubber, tighten the airbox bolts.
    I got where I can R&R the carbs in about 20 minutes.

    The flasher relay lives right under the fuse block next to the aux. power block inside the right cover. Look for a three wire plug.

      I can get my carbs out in about 10 minutes. The airbox takes 3 minutes more.

        Just removing/installing it in the right order in relation to carbs and upper/lower box helps out a lot. It is a little bit of a pita though.

            I can get the carbs off/on in less than 5 minutes. Its all about technique. I think it is actually easy. Just make sure all the bolts are REMOVED. Then you can slide the airbox back a cm or so. I Slide the carbs in from the bottom on the left. After they are in place underneath the stacks and intake boots, I just maneuver the carbs up into position. Pu them in the intake and push them all the way in. After they are in, you can slide the airbox onto the carbs. Put all the clamps and screws back on and you are done. Don't forget all the hoses. Also, it is safer to remove the vacuum line holders from the carbs and set the clutch bracket outward so that they do not interfere of bend.

              Ok,guess I was just hamfisted putting them on, hopefully practice will make perfect, I appreciate the feedback on how to do that. Figured out the turn signals, what threw me was that the Standard has an automotive type turn signal blinker under the seat on top of the battery, why are there 2 on a standard and only 1 on a special?

                I don't think anyone has mentioned this already, but if you leave the carbs off for awhile, the boots shrink a little as they cool off and harden a little. You can sometimes help them slip on by spraying a little wd-40 in the boots before installing the carbs.

                And ALWAYS loosen the retainer rings sufficiently and get 'em out of the way.
