Cold compression on the 900?

[Sask900]

I have an 06 900 SB, tested compression last night, 95 psi and 105 psi. Just wondering what compression should be, sled still runs awesome, should I be doing a top end? I am probably going to sell it next season for a pro, so what is an approx cost to do it myself?

Thanks

After I rebuilt my top end and broke it in mine had 105-105 at 7000 ft elevation.

What's did the top end cost you? Did you replace just the pistons or the pots aswell?

a top end for the 900 is around $250 if you do all the work yourself...just make sure you install the 2006 ONLY pistons, and the arrow (or dot) on the dome of the piston faces the EXHAUST/INATKE (or fwd)...

$250, where are you ordering your parts from because that is dirt cheap,

When doing the top end is there anything I should be aware of? (easily damaged peices, or difficult things to get at?)

143-147 psi cold stock heads @ sea level last month. Just over 1300 miles on new top end. Pays to do proper warm up and heat soak. Drive lightly for first 5 miles.

Phewwww, I done a compression check the other day, because there is no snow here and I had nothing else to do.
I got 125lbs X 2 and was all stressed out because I thought 140-150 was what I was looking for on a stock 900.
Thanks all for reducing my stress level.

Just finished doing the top end with SaskRMk, I see you are from Sask aswell, this whole warm weather and no snow thing is BRUTAL
