So I upgraded a couple years today to an '06 and I had always heard these were the best out of the box revs so never really did any research on them. Well after purchasing it I realize there are a few differences so I was wandering if someone can let me know what issues you can help me to avoid. I haven't really looked to hard into this sled. Are they still dpm in '06? ski-doo.com doesnt show it anymore so I want to know where I should have my carbs set to ride from 5500-1200. They also told me that Felkers in Denver set up the sled. Well can anyone tell me what Felkers set-up exactly consists of? Everyone tells me the same thing...clutching, gearing, carbs. But what are they actually set at since they don't seem to give out much information to the public. I just want a reliable sled and I want to know what I am riding and to expect from it so if something does happen it was my fault not someone elses. Thanks
