    750E airbox Battle Royale!

    So, I have to replace my airbox on my 83 GS750E and have heard horror stories about removing the motor etc. Please pitch in here with advice as to how to do this preferably WITHOUT taking the motor out! I really, really, really do not want to do that!
    I'm counting on you guys to save my ass here!
    Thanks

    Make sure you install new rubber boots and you will be fine.

      If it's like a 1100e remove the rear portion of the air box. Loosen the front part and push back on it. And yes it's a PIA.

        Likely have to loosen rear fender, push any wiring, hoses towards rear of bike and push air filter box back ( or out ) ;a half inch of extra clearance will make removal slightly less PITA. New pliable boots will definitely make reinstall easier, but you might be able to soften the existing ones. Extra hands are a plus!

          Everyone seems to develop a "trick" that works for them. Heating and greasing the airbox boots helps, some boil them. Others stick some round widening tapered thing (salt shaker) in the holes to try to stretch them after they've been heated.
          Some use a flat piece of cardboard to keep the air box boot edges from bending when positioning them near the carbs. Everyone has their own way. Hopefully it won't be as bad as you're expecting.
          New air box boots work wonders though! They're soft and supple, yours are probably as hard as rocks and they are going to be fighting you every step of the way. And while you're there, you might as well replace the clamps too.

            He wants to install an airbox on a 83 750E, not fighting carbs as of yet. just the box. Yes you may be able to get it in with out removing the motor but it will be challenging. I have read someone was able to do it by just removing the motor mount bolts and moving the motor as far forward as possible and they were able to get it in . I tried it myself and found it just as easy to pull motor out stick air box in then put motor right back in. Then you can follow everyones advice about installing the carbs. This model bike is a pain in the arse to install the carbs on. I've had them out of mine a couple times in the last 29 years

                I'm going to tell you you're best off Hjfisks advice.Even with the eninge loose it was easier for me & the wife to pull the frame off and then put the box in.

                  I tried every thinkable attempt to remove mine over the coarse of a few days. In the end there was only one viable soilution...

                  TOTAL DESTRUCTION...

                    You can remove the airbox on the monoshock GS750/700 without destroying it in one of two ways:

                    1: Remove the motor

                    2: Remove exhaust pipes. Unbolt all the engine mounts, then slide the engine all the way forward in the frame. Use tie down straps to keep the engine in place firmly against the front frame downtubes. In order to reinstall it, you may or may not be able to slide it back in without removing the motor.

                    Either way is a PITA. Don't do it unless you intend to put pods on the bike. If you never intend to reinstall the air box, then grab a hacksaw and saw away at it.

                      Aaaarrrgh!

                      Well, I WAS going to keep the stock airbox so I could avoid rejetting, but I think I'd rather re-jet than pull the motor. For pods, do you think a Stage 3 kit is best? Right now the airbox in the bike is broken in half across the part where it goes back through the frame, so getting that one out shouldn't be too bad. It's got the stock exhaust.

                        Pulling the engine would involve WAY less time, effort and frustration than rejetting...

                          Agreed, pulling hte motor isn't that bad. If you just jump right in and do it you should be able to do it in a few hours. unlike rejetting , maybe weeks getting it right

                            Or more likely never getting it really right, very few podded bikes run perfectly, with good throttle response, and get the same fuel consumption. It takes a LOT of effort, especially on the bikes with CV carburetors.

                              OOo kay

                              So what's the easy way to slip the motor out? I will be working alone without a lift or hoist. i just want to get it out enough to replace the frigging airbox, nothing more.
                              I see some hard, angry times ahead of me...
