the 800h.o cfi motor (2008 & 2009) motor out of Iq's, they are known for grenading at low miles(under 2000) do to leaning out and dangerous backfiring and overheating. They also had probelms with fuel mapping and needed reflashes that never worked.
only about half were tempermental. Some people have 4000 or so miles on their motors and have 0 issues other than 1 or 2 reflashes. But alot use PC5 or PCV to cure the reflash and fuel map problem.
I(d personally stay away from a 800cc 4 injector motor........ Just what theyre worth, isnt worth the risk in my mind.
Well that's what I taugh and I want to stay out of that trouble.
How about the[highlight=red] 800cc in Bombardier, I think there a lot better right?[/highlight=red]
I love the weight saving too. Artic cat is to heavy for me.
depends what years. pre P-tek engines were crap. onlt 140 hp and signle ring pistons so the flaked and took a crap around 4000 miles

if you buy a Liberty 800 that has the updates it will be more powerful than a rotax 800 (bombardier is the engineer of the sleds. not the engine maker) just figured id clear that up
The ring problems was in the 03 and 04 800 H.O. motors. The ring flaking wasn't because the motors were single ring pistons but because of the chrome coating on them. Most of those ring problems were taken care of with a recall. After the flaking rings were fixed the 03-05 800 H.O. doos were very strong, and as reliable as any other manufacturer. When Doo came out with the 06 800 powertek motor that is the supposed most reliable that Doo had out of the box. The 06 800 Summit is a pretty highly sought out Rev chassis sled. Your "only 140" hp sled was pretty much the norm until Doo came out with the 151 800r powerplant for the 2007 year.
Dragon 700, Where do you get your information? I don't know what you're talking about when you say Bombardier isn't the engine maker but the engineer of the sleds. Bombardier is the parent company of Ski Doo, the same parent company of Can Am atvs and Sea Doo watercraft. Ski Doo is the North American snowmobile division of Bombardier while Lynx is the European snowmobile division of Bombardier. Bombardier makes Ski Doo snowmobiles. You're quite misinformed about a couple things.
As far as wondering about the reliability of the sleds I'm a diehard Ski Doo guy and have heard mixed reviews about both the Ski Doo and new Polaris powerplants. With that said I'm looking for a 800 Summit xp 154 right now. If you decided to buy a 08 Doo make sure the sled has had all the updates done to it. There should be some clutch updates, drive shaft update, depending on the model there could be carb updates, and there are also a few retrofit kits to add a few of the new features the 2010 and 2011 sleds have. The 09 and '10 Doos should already have the updates done on them. I haven't heard of too many guys having problems other than a few isolated events.
If you decided to buy a 800 Polaris you also want to make sure that sled has had the 2010 update which I believe includes a new 2010 top end, a reflash, SLP pipe and can. I've also heard about the midrange bog, I personally have a riding buddy who I go on all my sledding trips with who has 70 miles on his sled has the new topend, but still has the bog. He's now decided to do the dynoport flash so he can only ride it 3,000' and above. There are other guys running the PC5 who say their sleds are incredible, ask MNSLEDNECKS about his. Other are running a fan and pulling 220 hp out of that sled and are enjoying the hell out of it too, talk with RMK-KING on here, Silber on snowest, or go to his website www.silberturbos.com.
Either sled you're going to decide on will likely have problems, it's a snowmobile, but you will likely be happy with your purchase if you decide to go the route of a 800.
