Both my 2002 ZL 600EFI and 2000 ZL600EFI have a Ylw-Grn spring (#0646-147) on the primary clutch. The Arctic parts manual suggests (for below 9000ft alt) that the stock 2002 spring is Red (#0646-149) and 2000 spring is Ylw-Wht (#0646-229).
Is the Ylw-Grn spring a better all-around spring for the 600 sleds? Is it likely that these springs were changed out to Ylw-Grn at some point as I bought them used?
I ride in Ont & UP which I believe is 600-1000ft above sea level.

It sounds to me that they have been changed to a ZR set up. I would also check the weights/cams.
2001 ZR600 have the Y/G spring with 539 cams, 4,000 engagement spec.
2001 ZL 600 calls for a Red spring with 592 cams, 3500 engagement spec.
My 2000 ZL600 has a Yellow/White spring with 609 cams, 4,200 engagement.

Here are the spring charts from my 2001 manual for comparison.

SPRINGS -

NOTE: The Arctic Cat drive clutch spring has a smaller O.D. than the

The 2002 has 520 cams YL/GR spring.
The 2000 has 485 cams YL/GR spring.
I had the clutch rebuilt on the 2000 by dealer, they did'nt change spring but did order 485 stock weights and I am wondering if this is why the clutching seems different. On hard braking, the motor seems to take longer to come back to idle.
I don't really understand the spring rate/cam weight relationship but if anybody has any suggestions on what spring or weights I should use that would be great. The cams & rollers are brand new and I would prefer not to have to spend big$ and perhaps only change the spring.

In short, your 2002 primary clutch set up may indeed be factory for that year, check a Service manual to be sure. Your 2000 is not.

The 2000 should have #0746-609 52.0 grams cams and Yellow/White spring, with a 4-4300 rpms engagement. With that said, your set up of 48.5 gram with Y/Gr spring (that I think you meant by 485) may react very similarly but I suspect that it has a slightly higher engagement speed around 45-4800 rpms?. If you don't like it that high, change it to the 2001 set up above with #0746-592 52 gram cams and Red spring. This will bring the engagement down to the 3,500 range. It worked nice on my 2000 ZL600.
