My 600 Voyageur is killing the PTO-side spark plug on startup. I've tested the plug each time it happens and zero spark. If I replace it - boom, runs great all day. Start it up the next morning and it's running on one cylinder again. Any ideas what could be causing this odd behavior? Sled only...

Good Morning, I have an 05 Polaris XCSP 600 anniversary edition, number 0072 and am wondering how many of them they made? I am also wondering what it’s worth with 4,000 miles, in mint condition! Please let me know!
