what years did the 800,2 cyl, have issues with the crank/bearing(s). also,were there any issues with the 700 (twin) motor,say like a 2005 vintage? here's my dilema=looking at getting a long track,would prefer something that can run trail somewhat. is a 151 or 159 too long?and if you had a choice,would u go 800 or 700?THANK YOU!!!

Have a buddy with the 2007 700 155 RMK and it rocks and not one problem. I don't know if any of the Polaris 800's had crank/bearing issues. I know the Summit's did. If you want to ride trails as well, make sure you get one with tipped rails. I don't think the older Edge body 151 or 159 sleds had tipped rails. Those started with the IQ models. Without tipped rails, the trail is going to suck on a long track. Driving a 144 or longer on the trail is quite a bit different than the 121.
Between my buddy and I, we've had 4 800's of the 2003-2004 era. Broken cranks in all of them. One didn't happen til 8000 miles, but the rest were under 3000. I've heard the 700 can have the same problem, but much rarer. We've gone to billet pto ends and big-boy bearings. So far so good, knock on lots of wood.

The 2000-2005 800 was a big block motor like the 700 and short lived 600 of it's time. The newer 800 is based on the small block motor design that really came out of the 440/600 race sleds.
The older big block 700's and 800's both had crank issues but those were more common in the 800's. There are many arguments as to what and why the cranks failed but crank wobble and small bearings are generally considered the main cause. Stock motors tended to run longer than modified ones. Either way it's good preventative maintenance to get the crank done before it goes out and ruins your weekend.

and motor out of the way. I sold a 153 because it was to long for me for the riding I like and the 136 is to short with the wrong pitch for the track I like. wish cat made a 146 like the assault.think this summer I am going to build a M with a EZryde 146 that is my Ideal all around length.
and I do know allot of the 00 01 02 03 800s had the PTO bearing go out .dont know after that most my buds switched to a M in 05
