Looking for suggestions on what exactly I should do to make my sled running at its best abilities for the start of the season... Change pistons out or just rings... Bearings replace...Other items??? 2009 Polaris 800 IQ with 6,000 miles. Thank you for suggestions!

Have you performed any comp. checks on the cylinders? Is it running bad, or losing power?
You could run another 3000 mi., or 3 mi. before somthing happens. You never know. I'd do at least a check before tearing into it.
Unless you want to, go for it.

You have a 09 Poo 800 with 6000 miles?? Dang, you are already ahead of the game! Do a compression test. If its good, leave it. It has made it this far, not many Poo 800s of that era can say the same.

is the rest of the sled well maintained? if so may be worth yanking out and going through the whole thing.
crank seals bearings and pistons.
if the sled has had min maintenance then prob best to slap a aftermarket top end in her and let it buck.
after 6k clutches are close to shot if still original skid bearings are long past borrowed time a arm bushings skid arm bushings shock bushing all close to gone if still stock.
as far as aftermarket top end I have had very good luck with spi stuff cheep but seem to hold up well there tolerances are right on there weights are closer than stock.I would prob not run them in a heavy mod but have done over 10 and I still know of 5 in my crew that are going on 5 yrs or more with there teens riding them now

I had the same question on my Polaris XLT at 6k. My buddy came over and we took a look at it. What was worn out was the skid frame. We rebuilt that, new fuel pump, track, seat cover, and left the engine alone. All three buddies (two of them who are/were Polaris mechanics) said the same thing, if the compression test is good, leave it alone. As catlac said, it could go in 3 mi or 3000. When it does I'll deal with it

Check skid and drive bearings fill with sea &snow and go!

I'm sure that was meant to get things started. With snow on the ground West of here the debates will surely start. Hand signals are outlawed this year in Michigan. Less signage will make for better riding.

Thank you for the posts...Last year I felt the sled was losing some top end power...Yes ALL parts are still the same...so I realize from the readings I am on borrowed time...A friend in coming over this weekend to do a compression test!!!

Great to know I need to check and most likely replace the bearings and bushings.

I appreciate the info before I take it to a mechanic.

I would start with the clutches, 6000 miles is A LOT on original clutching. Probably make it feel like you have a new motor.

I agree with checking the compression and if its good leave it. It goes without saying that the shocks should be rebuilt if they already haven't. My backup sled - a Skidoo 600 rev - has 9K miles and I just pulled the skid for the first time. I think all the idler wheel bearings and bushings are fine but I'm replacing the bearings as long as I'm in there. The bushings seem fine including the ones in the A-arms. Probably depends a lot on how well the sled was greased. Every sled is different though.

i have over 13000 miles on my 02 edge x 600 and have never touched my clutches. but i did toast the motor. dropped a valve. i agree, if compression is good i wouldnt touch top end.

Checked compression done with friend: mag side was 113. pto side was 120. Warmed up was 106 and 115.

Yes on the clutch needs to be cleaned/worked on.

The comp was lower at temp? That is very unusual as the pistons expand and the ring end gaps close you should increase comp at temp. When a 2 stoke burns down theres usually one or more contributing factors that cause it. Such as air leaks on intake or exhaust sides or fuel delivery issue. Every 2 stroke is ticking time bomb anyway so rebuild it or not its going to let go eventually. If you plan to keep the sled for years build it now or build it when it blows up to you.

Probably low # for that motor ????? The 7# difference is right at the edge of disparity. 5# difference is the accepted norm. ( JIMO )
Maybe freshen up the clutch springs and run it until failure. Could last a long time.
