    Hi there,

    So yesterday, I was getting my xj700 maxim ready for some frame mods when I noticed a huge crack in the frame about half a foot long! Its in a really annoying place which will make it difficult to repair. I have been looking online for another frame but can't seem to find any. I have found loads of xj600 diversion frames or xj750 secca frames. Will these fit easily? What is the easiest frame for the engine to fit in, other than the obvious? Is there any information online about doing this?

    I hope someone can help me out here.

    Thanks

    i betcha chacal has information about this. I would ask the professional. send him a private message or email for assistance. info@xj4ever.com

    if a 650 frame would work, thats the only spare frame I got to help you with. sorry plus shipping to London (thousands of miles away from the U.S.A.) would be outrageous lol

    Get another xj700 frame. If you have an airhead you can find frames pretty easily on ebay. If you have an X, you'll have a much more difficult time.

    Yeah, maybe in the states they are easy to come by, here in the UK they are rare as rocking horse.

    well, Len's in the states, too..................

    Didn't realize that's where you are. Question--where is the crack that you could have one so long? The only place I can think of would be in one of the down tubes. In that case, pull the engine and weld it. Next question-- what CAUSED the crack? That would be more of an issue to determine before doing anything.

    My opinion........

    Can't you have the crack welded at a machine shop or mechanics shop? You'll most likely have to disassemble the bike which you would need to do changing frames anyway.

    The crack was caused by a crash my brother had on the bike about 5 years ago, at the time it looked like no damage had been done, but by the looks of this crack the engine bolt has shocked the frame and the crack has been getting since. I noticed it last night it runs from the engine bolt on the left side, running forward and up the front curve. Its bee totally invisible because it is under the bike. I had a frame builder look at it and he says it will be a tough one to repair, but i may have to go down that route if I can't find a suitable donor.

    Is it not something you could plate over, what with it being underneath/out of sight?

    You'll have to remove the Plant ... even if just to swap-over to a new frame.

    Get the Engine removed and have the damaged area assessed by a Professional Welder capable of doing Plasma Cutting & Welding.

    You might be able to have the damaged area repaired and strengthened.
    The Frame might need a tubular insert and reinforcement.

    A used Frame will require legal issues and Title related paperwork.

    See if this firm can be of any help to you.

    Lower 48 in general. Otherwise Central Mitten.
    The easy way to take care of this problem is to replace the affected section of the frame.

    Find a local bike breaker/salavage that has a 700 frame. Get the down tube, and lower frame cradle. Have your frame builder weld in the new replacement piece.

    Even having the piece shipped from the states would save the frame, and avoid any legal issues associated with a frame replacement.

    This makes the most sense unless you happen to find the right frame overseas. Welding in a section is not that complicated for a professional welder.

    I found a crack on my 750 Maxim, it was probably caused by water getting into the frame and then freezing during Minnesota's winters. Though your crack is much more serious, it should not be any trouble for a qualified welder to repair.
