Seems to be a lot of issues with the new viper, was thinking of buying a new one, now not so sure. after reading the posts in the viper section, its seems like a dud. not sure about this joint venture with cat. starting problems, loose rivets, reverse gear problems. I just rolled 16,000 kms on my 07 apex, still runs greats, no real problems except bad donuts, which I changed several years back. the usual things replaced, sliders, bearings, changed the coolant this year. new spark plugs, couple of idler wheels over the years, it has been a great sled. fast, good on the trail, maybe not the best suspension out on the snow, but I have it set up just right, I think I will keep it and try to get over 25,000 kms on the sled. I also am used to the power of the apex, going to the viper could be a disappointment, unless I get a turbo, but I don't really want to spend $3000 extra to get the turbo.
