im assuming its not a rev??? I owned a zx for a few years and i loved it...I wish i still had it. I liked the look of them better then the rev...just something about the zx i liked alot. Never had any problems. It was a really great sled!
2800 miles on my original rings. I've talked to guys who have 6000 mi.+ on the stock motor. The rings are the most significant issue that I have heard of. Maintenance and good oil = longer motor life but no motor runs forever.
I am not a big fan of the 03 rev 600s. That is why I got rid of mine. Other then the ring issue I guess they are not that bad of motor. I also wonder if it is a rev or a ZX. If you doo get the 03 rev 600 ho - get new rings, rejet it, and gear it down. Then it will be good. P.S. I like the new 500 SS motor or old 600 motors. In my opinion those motors were bullet proof, efficient , and great performers.

Why do you need to rejet it?

Those sleds were notorious for being jetted way too rich from the factory. That is why they get such poor gas mileage. I don't know where you ride and elevation you are at so I couldn't suggest a particular jet size but definitely look into dooing some jetting. It will make it run much better. Contact Big John @ Sled Head Racing for jetting info.
-Good luck
