rear suspension sagging on my 2001
zr600 efi not all the time
sometimes in morning when cold
somtimes in middle of hard ride
somtimes just fine
grease suspention often .
if it happens when its cold maybe the fluid is compressing? just a guess. May want to try new springs if they do nothing maybe shock rebuild. Heard of the cat shocks needing rebuilds often. Not sure how a coupling kit would help. Thought all the does is sort of couple the front and rear suspension to prevent torque up and lifting the skis.
what kind of track shocks are on your arctic? im not sure, but did arctic use the "arctic cat technology"or act shocks on the rear suspension?? they are rebuildable, and it could be possible that you have a seal leaking down in them, just my thoughts though.
they used ACT in 2001 i know for sure, i had a friend with them on his 01 zr600 efi, but did they use them on the rear suspension as well???? any 01 zr owners out there that know??

Arctic Cat shocks all seem to have a tendency to sag. Usually the sag is between 1 to 2 or more inches right at the top of the stroke, or full out. When you push down on the back of the sled there should be just a little bit of sag and thats normal. Also the shocks will fade a little when they get warm. they just get extremly soft, then after they cool off they are fine. You can rebuild them as many times as you want and you will still get the problem. For racing we rebuild shocks every weekend, and have the same problem everytime. Our shocks are a little different than the consumer, but work basically the same way. Any other ?'s i can try to help you with best I can as I do quite a few shocks and setups.
