What's the downside of the wrong CDI Box?

[BorderView]

It seems my sons 1987 Yamaha Warrior needs a new CDI box. Found a great deal on a CDI box off a 1989. Can't seem to confirm or deny that there is a difference between the years. We have, however, seen many examples where the 1987 has unique parts. It was the first year of the Warrior. I don't mind buying the part, and if it does not work, selling it. It's that good of a deal.

My Question:

Can I wreck other stuff by installing and attempting to fire with an incompatible CDI box?

Any educated thoughts sooner rather than later would be appreciated.

if it looks the same try it, if it works your golden if not your out the dough, I don't see any downside other then the cash outlay.

The CDI from a 1987 fits only a 1987. They updated them many times after the 1987. There's one here; check out [You Need Authorization] then search warrior CDI
