Does any one know if a 02 MTN 800 CDI box will work on a 900?
or can they be re programed? In the process of turning the 800 to 900, I got most all the parts but just thought about the CDI box. TIA

It will work as is, but a true 900 one will work a little better in the midrange.

We ran 800 CDIs on our 900s for quite a while before we got them all switched over.

There are also at least 4 different 900 CDIs, but I think only 2 different timing curves. The ZR CDI has 2 degrees less timing on the top end than the Mountain version.

Year doesn't really matter. Some people think the '03 has a slightly hotter curve, but I've never been able to verify that.

The '03 one you found will work fine.
