I would want to know what caused the upper end to fail. The 800's are well known for crankcase/crankshaft issues. If you get the sled cheap enough, it may be worth your while, but cranks are 900 bucks, cylinders, 400, pistons 150... throw in another 140 for gaskets and crank seals, replace the aluminum VES valve guillotines with stainless steel, replace the old VES diaphrams too, that's another 200 or so. Gets spendy quick. You may also have crankcase issues on that engine, a lot of them are out of spec and may require milling and line-boring.

The 800 makes a gob of power, but they are high on maintenance. Go in with your eyes wide open. If you like to wrench, they are prettty easy to work on

If you had experience on the sled and really thought the ride quality was perfect for your riding style, and you were going to keep the sled for a few years, it may be worth it. But if you have no experience on the Edge chassis, you could put 2600 bucks into this sled and not like it at all. It's really a crap shoot. I have a buddy that bought a 2003 RMK, blown engine, for 500, he bought one of the engines that went through my fire, and between his broke one and my burned one, we got a runner out of it for pretty cheap. You may get lucky and find an engine for a lot less than repairing that one, although you will still have the crank/case issues on any 800 you buy...

What about an 05 XCSP 800. I thought they had issues with the 800's early on, but resolved the crank issues in 03 or 04? Mine's got 145 PSI per cylinder. Is that about right for an 05 that has never been rebuilt?

Thanks,

When I bought my 04 800, it had about 1500 miles on it. I sent the crank/case to SLP for the wide bearing, the case had already started to fail and the crank was toast. I had to have a new crank, and they were able to mill the case and line-bore it. I put 2500 bucks into that engine before I got to ride it. I have friends that had 05 800's that had the same issue. Some engines go lots of miles, some not so much. If yours is running well, send the clutch off to have it rebalanced to help make sure it stays that way

145 is plenty good for compression.
