Is there other cdi's that can be used on my 97 zrt 800?
If so what are there part numbers.
The current part is 3004-812 new at 500.00.
I'd like to go with a used one but can't find a list of old part numbers
Any cdi from 1993-1997 will work. All triple ignitions were "closed" from those years and will work. The ignitions starting in 1998 were considered "open" ignitions and worked differently. You can use virtually any cdi from a zrt800 or 900 from 1993 to 1997 but the timing curves to vary a bit from year to year. You should be able to find a used 1995,96,97 for less than $100. The 1993 t-cat 900cc cdi is the most sought after cdi due to the fact that it has more timing in it than any other year. If you want an actual list of pt. #'s, you can go to brownsleisureworld.com.
