Hey everyone,

I was wondering is anyone knows if the frames are any different for the 1985 & 86/87 style 250sx? I recent pieced together a 1987 and was able to get almost all original 1987 parts. However, the frame is from a 1985 model.
Everything works great and the trike drives fine, but the whole top half of the rear end sits crooked. the axle and swingarm look level and the whole frame looks to be sitting crooked on the attachment bolts.

The frame/forks/swingarm/axle all seem to have no bends or warping. i think the problem might be where the swing-arm attaches to the frame. Since the '85 models have a different style swing arm than the 86/87 i think maybe the center tube that the swingarm attaches to could be a different size?

Please let me know if you have any ideas.


Thanks
