Is 800 normally open or closed. This 600 is a closed circut. I may need the magneto. I think the pipes would work because it is going in a 600 machine and they are triple pipes too. Plus I think you could re-jet the carbs to work.
I have a complete chassis '97 800zrt. All there but the motor, clutches and ignition. Body good shape, seats great, track is poor. I have a good .850 track with studs also. You can buy all with track for $500 or I can sell you parts separately. Let me know what all you need. PM me if you want.
97 and older ignitions are different than 98 and up. 800 cdi is different than 600. Stick with 800 pipes and 38 carbs for the 800. I am in Northern IL.
