    Going to start working on a 83 750 Maxim.

    First thing on the to do list is reinstall a factory air box. Wondering if anyone has any sugestions. I'm going to pull the carbs and boots off of the head. Do you guys think it will slip in from the RH side of the bike or is there more I would need to do to get it in there.

    Thanks

    Good question!
    I tried to remove one from an '82 750 Maxim and there's not enough room to get it out with no carbs or boot in the way. It appears that the bike is built around it . 8O
    Some have cut them in two pieces to get them in and glued them back together once installed. I'm sure it can be done using GOOP to glue it together. That stuff is amazing!

    I guess the air box was put in before the engine went in the bike then.

    the plastic that the airbox is made out of is very hard to glue... I'm willing to bet that even a bead of goop will come apart eventually.

    AFAIK the only XJ that allows an easy removal/installation of the airbox is the XJ1100. I believe you have to pull the motor (or the top end) to get the box in and out on the rest of the XJs..

    I gaurantee GOOP will hold it together if applied properly. I know first hand the power of that stuff. I've used it for years on just about anything I can seal or glue. (no I don't have any interest in the company)
    I made a live well in my boat, using five pieces of aluminum plate and used GOOP to hold the corners of the aluminum together. It not only holds to this day (it was made 15 years ago) it has never leaked one drop. The aluminum was from a sign (STOP sign material) and worked perfect for the project.
    I also used it to replace a short section of oil pan gasket that came out of my truck engine (pan was over-tightened and the gasket slid out the side and leaked a quart a day) I just ripped out the short piece of gasket and squeezed in a layer of GOOP in the gap where the gasket came out and let it sit for 1/2" hour before re-tightening the oil pan. It doesn't leak now!
    A simple project like holding an airbox together would be a breeze and work very well. I'd bet money on it if I used it to hold the airbox together. Go for it, unless your deciding to pull the engine.

    I was looking at it just now and if the engine mounting bolts were taken out if the engine would drop down enough to get it in there. I will just have to see and let you guys know how it went. I'll be working on that one this week at night. I'll keep you posted. Maybe some pics if I can get my camera to work.

    Just incase you some how screw that one up while your working on it, I have a perfectly good one here you can have if you need it.

    Painter, I do not deny the power of GOOP, and I use it quite a bit myself.. The problem is that our airboxes are made out of some polyethylene-like plastic, which is flexible and very slick, and hardly anything bonds to it, let alone dissolve it.

    The same type of plastic is used to make containers for petroleum products and a whole host of glues, because not many chemicals will touch it.

    Stereomind,
    No doubt you know what your talking about. You prabably know more about the airbox material than I do.
    I just don't have a doubt it would work to hold it together, that's all. Guess the only way is to try it.
