I measured the frame from the swingarm bolt straight forward, and it was almost exactly the same measurement as my 04. I think I'll be good on space.

Thank you for the votes of confidence.  I have been having multiple "what have I done?" moments the last few days.  Earlier I was thinking about Sandblaster's AF project that used the cradle from a 2001 CR 250 two stroke.  I think that may make the most sense, as it will give me the higher Y piece with the rails already attached.  That way I just have to worry about trimming and adjusting as necessary.  I think the picture angle is misleading, as there is more room in the frame than it looks like.  I think the 250 should fit just fine.  If I was going to do a 500 that would be a deluxe wrestling match.

I'm going to use the two stroke radiators if possible, so the mounts will need to be redone on the bottom anyway. I think that would be easier than trying to put the much larger four stroke radiators back on.

I grew up working on hot rods with my dad, so I'm used to making stuff that isn't supposed to go together work.  I guess I need to just remember this advice:




   

I was working on getting 2017 plastic put on my 2004 KX250, which involved buying the subframe, tank, and plastic from eBay.  I recently sold a couple of my bikes, and have been wanting a newer bike for a while.  Unfortunately Kawasaki has basically said screw two-strokes, so we are at an impasse.  I figured putting new plastic on my old bike would be as close as I would get.  In the process of buying the subframe and tank, I noticed that the guy had all the other components of the bike as well.  He said to contact him directly if I needed anything else, so I called him and inquired about the frame, swingarm, triples, and linkage.  He offered me a deal I had a hard time refusing, so it looks like I am off on an aluminum frame project. I haven't had a new bike in 26 years, so I pretty excited about having the latest and greatest.  

I spoke with Fl_sharpshooter about his project, and felt pretty comfortable with the project until I got the frame out of the box yesterday.  It looks like Kawasaki changed some of the design of the frame.  The y in the frame is now part of a larger piece that extends up to the steering stem.  This obviously negates the ability to grind away the weld and remove the y for re-positioning.  I guess at this point I am going to have to cut the frame and add something inside (like the old y joints had the solid tab that went inside the frame) and outside the y (plate weled onto the frame?) to reinforce the joint.  Anyone have any thoughts on if I'm on the right track?  I only get one shot.  

Looks like you've got your hands full. Just try to take it 1 piece at a time, it can definitely get overwhelming. The y-piece looks really low on the newer frame. I would seriously consider looking for or making a total replacement y-piece, I can see the radiators are going to give you a fit too. Not sure how tall the 250 engine is, but looks like you're going to have to extend the cradle too.

sounds good umberto , you will succeed , but i think you should punch out half a dozen frames and sell the rest , i have a 01 250 engine looking for a home , and the 17 are great platform , and when it completed you could show the out of touch japs this is what you should bring out.

In case anyone stumbles on this, it does work just fine.  I used the KX250 wheel spacers and cannot speak to KLX wheel spacers since I did not have them.

The bolt pattern on the sprocket is the same but the disc break is different bolts and pattern, so replacement discs would need to be spec'd for the KLX.  But, it is the same diameter and disc position so no worries about it working.

Hey guys. Been a while since I've posted. All the mechanical fabrication is complete so it's been mostly a lot of finishing work. Getting pieces powder coated and painted. sanding the tank and tail down tonight to get it ready for primer and hopefully paint this weekend so long as the weather allows. Taking it to mid ohio in 2 weeks so it has to be ready by then! LOL wish me luck!
