Yeah, pretty much anything that wires up exactly the same should work...Like a KX125/250, KDX200, etc. The CDI mapping/timing curve might not be the same, but the bike should still run decent (could even run better to your liking, or worse...LOL).
'91 KDX 200 Project $300 KDX
'95 KDX 200 Project $600 KDX
'94 WR 250 Always a project

Gotta remember, the KDX CDI is set up with 2 different timing curves. One for when the KIPS are closed, and one for KIPS open. I think the change is at about 6k rpm. Slapping on a different one could have some pretty interesting results. I wonder that about the product moto_psycho is trying out as well. Did the designer consider this?

these 4 curves in conjunction with altering the stator to suit should give you the info you need
