I just spent the past week in Rangeley ME and put on another 1000 miles so my 04 has 4,500 total. A little about me for comparo reasons, 36 yo, 5'7" 180 and in peak physical condition if I do say so myself. The only changes I have made to my sled are a 80/100W bulb in one side and a 55/60W yellow in the other, a 2" Powermadd Riser and adaptor for of 3 1/2" of rise, that along with the 4" handlebars give me 7 1/2 overall, higher than an X-package with a 6" riser, nice. I even have the stock mobile windshield on the sled as it cuts the wind just fine. People notice that when I ride I don't even have to lean to get the sled around the corners and as I have been spending alot of time standing while riding all it takes is an easy tug on the bars, no leaning, just stand there and enjoy. I have changed my sliders at 2,800 miles, they still had alot of life but I was concerned about putting on another 1000 miles might have cut it close. I put on 4"+6" carbides at 2,400 miles and much to my surprise my left outside carbide is completely toast while all the others are good to go. The only explanation I could come up with was as I ride to the right of the trail and the outer ski is on pavement more/bad trail, it wore faster but right down to the host bar, carbide inserts were gone??? I put in 48 studs and this is why. When I first got the sled I noticed that the sled was not tail happy as in the rear end didn't want to fishtail in the corners and I didn't want to lose any speed with all the added rotational weight. I go just as fast and the same places as people with 144, 96, or 192 picks and have not a single issue with control. For example, this week I rode with Thundercats, Poo 800X's, Doo's with all sorts of picks in their tracks and I was able to outhustle them every turn of the way and more studs wouldn't have given me any more of an advantage. Anyhow, that is what I got for studs in there. I changed the belt at 2400 miles as well and I plan on changing it again this week as I have 4500 on the second belt. I am also going to get another set of 6" carbides so I'll have 6" inside and outside. I will be one to say that the Indecision/Precision skis are the balls on groomed trails. I just hang off the sled and the sled just rails, people marvel at how close and precise I stay on the inside of the turns, I have complete confidence in my front end. I notice all too many people who complain about the skis and I'll bet all they do is turn the bars and expect the sled to rail. I wonder how much flack I'll get from this but one has to ride the sled, not let the sled ride you. I fouled one plug early on when I had the sled and haven't fouled a plug since. Sled starts first pull hot/warm and on 3 pulls cool/cold. I run 87 octane and the Bombi-full-synth oil, not a single problem with the motor. I grease my zerks after every ride/weekend of riding, I was even able to get to the two front steering ones without removing the exhaust pipe. On my weeklong trip, everyone wanted to and did try my sled as they wanted to experience what it was like to ride a true stand-up sled and everyone loved it. At least 4 guys who owned Cat/Poo are going to get a REV. They saw how easy it was to go fast and handle so well, and along with how fresh and unsore I was they were sold. As it was, me and the only other guy with a REV last week would go out at night for another short 30 miler after a 150 mile day. Everyone else was beat from riding their old-style sleds, I pitied them. So all in all, the 500SS is just an insane, reliable, fast, comfortable sled, I've got 4,500 miles on mine to prove it.
