Hey all,
I bought a '90 KX250 as a project bike to tear down and restore. It was fully assembled when I got it. I tore it all down, cleaned, replaced anything necessary and am now starting to reassemble. Problem is, I can't get the swingarm back on. It will not fit back between the frame and bracket on the brake side. The chain side fits fine. For the freaking life of me I can't figure out why. It's just too tight to fit by 1-2mm. Again, it was assembled when I got it, so it's clearly user error. Any ideas?? Thanks in advance!!

At this point I'd get a pike and pry the framerails back apart!

Some pictures of the Swing arm - with bearings installed might help us see what's going on there.
Also some pictures of the assembly as you are trying to install it--- Like, show what doesn't fit and where.
I believe the swing arm assembly needs to be fitted near Exactly square/parallel with the frame/mounting bolt holes.. slightly crooked and it won't fit.
