2005 600 summit

[skibeadoo]

I just purchased a summit 600 and found the engagement to be at 5000rpm. It appears to be a white white spring. I was told the stock spring what violet/white but cannot find that start or finish weight anywhere. Does anyone have the suggestion to run the sled in alberta and occasionally in Revy. Thanks in advance!

My 04 has a violet/white and engagement is 4000. I am going to try a blue yellow..supposed to be 3500 engage
