Is it worth it to change to an newer model CDI and wiring?

[turbowrenchhead]

I was wondering if I should replace my 25 year old wire harness with a new model year harness and cdi. Are there any advantages with the newer model cdi's?

No.

Unless it's damaged.

Wiring is slightly different, so I think you have to replace stator, cdi and all wiring. If you choose to.
