I just passed the 6,000 mile mark on my 16 7000 eltigre. I managed about 2,800 miles this year. I'm done for the season, and will jump into a maintenance teardown. Looking it over, it shows no signs of wear, anywhere on the sled. Even the hyfax look like new. I figure I'll change the jackshaft and driveshaft bearings, any seals in the area, have the shocks rebuilt, and I think I'll pop off the valve cover to check the valve adjustment. I will also pull the clutches and check their condition. All in all, I've been very happy with the sled. It took a bit of getting used to following my 2 1100na's, but with each passing mile, I got to appreciate it more. The reason for the teardown now is that next season, if it is a good one, I could put on another 3,000 or more miles. Also the bearings, etc will be 5 years old by then, and adding the miles to the age, I think it's time. As I get into it, I'll report the findings of what is, or isn't good.
