Long Rod Conversion from PAR is a better fix. A few more $$ but you get what you pay for

1200 mile, pulls better, holds rpm. Not issues at all
Anybody run this with their head? If so, what compression ratio?

Terra Alps uses cast Japanese pistons, best reliable pistons available.

I have the head on mine
Ran one in my Mono all last year. I also have installed alot of "the fix kits", I was surprised that the Wossner Piston BMP uses was not just a AC 800 copy (previous kits I installed where just Wiseco M8 pistons). I will be running and installing more of the BMP kits in the future. I was primarily a Wiseco guy and had really good luck with them in the 800 CFI's, but really like the Wossner's designed by BMP. Will be running there 875 or 860 pistons next year.
I do like the long rod kits, but after you put new pistons in with it, your $1500.00 deep. Also when talking to some Polaris guru's (including employee's), that might not be the fix either.

So I just installed the bmp fix kit. 2800 miles stock piston looked fantastic. Defiantly didn't need to replace but hey I was in there that deep. Problem I had when I was in that deep I didn't get all the coolant out of the jugs. Well you all can guess what happened. A bunch went into the crank tried to get it all out. But aside from pulling whole motor did the best I could leaving it in. Installed all new parts from kit buttoned back up. Did start up started right away and idled a little low but 12 seconds later idled fine. Ran it at idle until 170 degree f and shut off. Lots of oil crap out the exhaust but that was to be expected. I have now done 7 heat cycles not a lot of oil comes out when running but leave her over night 10" pool on garage floor. Am I screwed or will it clean it self up? Also it starts easy and runs good have even done some 30 seconds at 5000 rpm and a few wot for a second. Any advice or help is appreciated tahnks

mop up best you can with gasoline on the oil stain and then kitty litter to soak up the rest.
thank you.. so then you think sled will be fine. just give it a while to burn off the crap?
R
Yea, you can't get things hot enough to burn things off, once on the snow and under a load, things will be fine.

I ended up buying a fix kit from mcb performance. cast pistons,gaskets,shim,and dowl pins. I heard a lot of good stuff about them. I like the fact that thet are cast pistons

I'm gonna try this kit this year just wondering if its worth it to put the low altitude head on or am I gonna have det issues?
