Dale Daudt of Jenkins, Minnesota says; “I am writing in response to John in Connecticut with the clutch engagement problem on his 2007 Ski-Doo MX Z 500SS with electric start (Dear Ralph ‘It Ain’t Right’ March 2008).
I have experienced the very same problem from 0-10 mph. I installed a TEAM primary spring, part number #210141-014. This spring has a rate of 160-380, so you could also use Ski-Doo part number 417 222 703 which should also be a 160-380 rate spring. Your problem will go away!”
