I have a 97 formula 500 that i bought in 2001 it had under 2k now i am at 4,025. It still has just about origional everything. Maybe i am making a mistake putting new slp skis and a sc10II in this sled but i figure i might get another 2 years out of it. How many miles do ski-doo twins go? I know the tripples seem to crash fast because of the bearing problems, as i recently discovered with a 98 formula III i picked up. But my formula 500 still runs great, 120psi in both cylinders. I always have changed chaincase oil and cleaned the carbs and tried to keep it in the best shape possible that is why it still looks brand new. But when should i worry about drive bearings and my clutches? Should i clean the clutches and replace the bearing this summer for fun(lol). The way it runs i wouldn't be surprised to get 7k or more out of it. should hit around 5,500 by the end of the year. I would like to hear how long everyone elses ski-doo's have ran for.

My '94 Formula Z engine lasted longer than the chassis. Last I knew the engine had over 14,000 miles on it. It has been used in 3 different sleds and 1 season on water crossing duty. Tough motor. My '96 MXZ, when I lost track of it, had over 12,000 miles on it and that sled had never been touch. Again, tough motor. Both 583's BTW.
