Their pretty good sleds. I was quite happy with my '94.
As you have probably noticed, they aren't light. For the few times I was on trails, I never had a problem with darting.
Those 580 motors are pretty snappy. I didn't have any trouble keeping up with newer Arctic Cat 600's.
There was a few issues with the early ZR's, but yours is new enough to get past those. One thing to watch is the wires that go to the carbs. If it goes haywire you just have to bypass the switch, pretty simple.
Suspension has alot to be desired of. The Fox shocks "should" be rebuilt every year. Every other years seems to work ok to. It's an amazing difference if the shocks haven't been rebuilt recently.
The rear skid off of the ZR2 chassis and the ZR3 chassis measures up if you wanted to upgrade the suspension. I'm not sure about the front, but it seemed like it would work.
Top speed runs about that 90-100mph range. If I remember right the horsepower is about 95-100.

very good motor, first thing id do would be bypass the sensors on your carbs and the switch at your throttle..... when these things get worn out and start acting up the sled gets a major bog to it... if u bypass them right away you dont have to worry about that
580's had issues with piston skirts breaking, I had a 94 and a 95 and they both did it. Also, make sure to check the driveline PTO side bearing, they are a weak spot. If the speedometer fails, suspect the bearing is going. When the bearing starts to fail, the driveline starts to drop down, and it shears off the drive key that drives the speedometer gear.
New bearing is about 25 bucks if you replace it early. Repairing the damage if you don't is way more expensive. I just helped a friend fix his 99 ZL 600, speedometer quit, he ignored it, bearing failed, he had to replace the chain, the lower gear, both bearings, chaincase cover, driveline, and a couple flanges, over 400 bucks. Heed the warnings!
I really liked how the ZR cornered, and the engine was plenty powerful. Like mentioned before, with the right snow, they get right up there. They don't go so good in the powder, though... which is the only reason I sold 'em...

how would you bypass the switch? i remember talking to someone else about this except on a yamaha, would it involve looping them together? where do they connect to the switch?
how long of studs can i put in before the radiator is in danger?
and one last question...the dip that put the front foxes in put them on backwards. would this affect anything? im going to switch them this weekend, along with 170 some studs and new throttle and choke cables.
would i have any problems with this many studs?

to bypass the switch just disconnect it and make a little jumper wire to loop it.
