I can't resist the prices being offered right now so I am knocking around the idea of trading in my '06 Summit X for an XP Everest 154".

I am hesitating a little because I rode an XP earlier this year and it seemed to take a little more effort to lay it over or pull a doughnut. :confused:
I have heard from guys that say after the learning curve it hands down the best handling sled they have ridden.
Others have said that they hated it. I know one guy who sold his sled at a huge loss with 250 miles because he could not figure it out.

Let's hear your opinions.


Also I can't leave anything stock so I'm just wondering what mods are best:face-icon-small-ton, in this order.
suspension (shocks, stiffer springs...)
handling (ski's, big wheel kits, risers...)
Clutching (Dynamo Joe kits??...)
motor (heads, exhaust, big bores...)

Thanks in advance.

I'm buying the everest instead of the X because I want to upgrade the schocks so no sense paying for the TA shocks.

LOL did i read that right? He sold his sled with 250 miles on it because he couldnt get onto it!?!?! Haha well he really worked at gettin onto it didnt he.

Best mods are to put a can on it, get a clutch kit and learn to ride it. JMO But learn what it can do before you start changing much. Its really hard to see a relevant gain when you dont no how well one will go until you ride it for awhile.

My learning curve was a little different because I went from the REV chassis to the XP. However, I rode an M8 earlier this year. I liked the power and feel, but I don't like sitting behind that big front end. Riding my XP is a lot like riding my 450F. All it takes is a few rides to get the feel of the sled and you'll never go back.

I don't know anything about anything, but here are my suggested mods:

Suspension - especially on an everest
SLP - High Flow Intake (good for deep powder)
SLP - Single pipe and y pipe
Power Dome billet heads
V-force 3 Reed Valves
Some kind of can - I did HPS, buddies have SLP

Those are the mods i've done on my sled (except suspension). I didn't do any clutch mods, but had my dealer make sure it was all working (especially after I my bushings went to pot). I am thrilled with the sled. Now just saving up to get the engine ported.:p

Do the head and exhaust mods void your warranty?

Go to an inner wheel idler wheel kit, makes a world of difference. I have had two XPs and leaning it over was NEVER a problem, I really don't know what those other riders are talking about. I can carve that thing easily.

X2 The best first mod is a clutch kit hands down! and get rid of the 20lbs of foam under the hood that like to hold water.

Oh yeah. Vent kits, new shocks, remove all foam, HPS can. I went a step further and installed an SLP head (8000'+) single pipe and y-pipe. SLP can is on the shelf. I installed a set of V-Force reeds and I am in the process of re-gearing to a 19t top gear and re-clutching it to match my 08 clutching. My 08 ripped hard and didn't burn a single belt, so I have to do some changes. I am going to install some carbon fiber RSI backcountry bars with hooks and heaters. Better Boards are sitting on the work bench. Trim the tail flap, the long one looks a tad gay. I installed a set of scratchers and pulled all idlers. I don't ride in low snow conditions or trails.

Mods:
Rode pretty much stock last year. 08 154 xp summit
Except: HPS can, removed foam/ plastic, some venting, alinged clutches.
This year: DJ clutch kit, Tom's Evol air shocks,and a Ski doo 600RS intake.
The Evo Rs in front and Tom's rear set-up, all I can say is it is a whole diffrent sled I love to ride it even more.

Good luck and have fun.

I am on my 3rd XP 800 - 2 x's and 1 Everest and have had a few different mods. I also ride with a group of guys who also have xp's and I have had a chance to see what works in our sleds. Here is my opinion on what you could do to YOUR sled to get your best bang for your buck. For more power go with an SLP (or other brand) hi comp head. You don't seem to get alot out of the Single Pipe, or Y - pipe over the stock from what I have seen. I like the weight savings and tone of the hps CAN. Much lighter and sounds Bad AZZ compared to the SLP can. This is important because if it sounds like its going fast it will FEEL like it it Haulin' AZZ. Anyway, For deep powder riding I think the SLP air intake is a big help, and for vents you can find great deals here on this site just look around. If you are an agressive rider I would look to get the X model windshield for your Everest. Much better for rolling your sled over. Just find somone who bought an x for his wife and trade them winshields and consoles, then you won't have the holes in your console. For track speed I would suggest the Roosterbuilt kit. Comes with a 20T top gear and you will loose some top end speed, but it does hold consistent RPM's and makes a little more track speed than stock, I like the way it works. As far as having trouble laying it over install the swaybar disconnect. It is so easy to remove when you get off the trail into the powder, and just as quick and easy to put it back on if you want to haul ballz down the trail. It is only 4 inches long and I just keep it in my pocket, (Just like TFA does with his 4 inch TOOL). With this off the XP will lean over as easy as any sled out there. I rode in McCall with a bunch of locals last week with a large group mainly all on new M sleds. They were all commenting on how they thought my xp carved on a dime and layed over so effortlessly.

Lots of good info here. Anyone been switching out the stock track for the camo xtreme? Are you finding this to be a major imporvement over stock? I had the 156 on my 04 151 and loved it but I wasn't sure it would make that much difference going from the 154 to the 156.

1911freak
03-18-2009, 11:38 PM
Thanks for all the comments. I picked up my '09 Everest 154" today.:D

I think I'll swap the head and stock can out with SLP and HPS and add the sway bar disconnect. Definetely a 2 wheel inside kit.
I think I'll ride for a season and then swap the shocks as well.

I'll have to look into the Roosterbilt kit.

If you are an agressive rider I would look to get the X model windshield for your Everest. Much better for rolling your sled over.

Does the smaller widsheild really make a difference in handling? No doubt they look better.

I put a bunch of money and time into my 09 146x and I honestly can say that the thing I enjoy the most out of all of it is a Boss seat. I didnt mind the stock seat but the Boss is a HUGE improvement!

I also heard that there is a big performance gain in the thermostat/ housing upgrade.
Also there is a reflashed ECU available.
Have any of you guys done these? and did it really help performance?

My friend did the engine tech thermostat housing on his - lets you run a 120 degree stat off an '03 HO, opposed to the 140 degree that's on the xp's now. He noticed a big difference in sustained power on long pulls and multiple consecutive laps at a hill, runs the cooling system before the engine heat fades so badly. I'll be doing one to mine soon too, makes total sense. Otherwise I don't think there are any real great bolt on power adders for the xp, you can do a head if you want to run 94 octane and maybe see improvements in power, maybe in the mid range maybe on the top end, it doesn't seem to be a guarantee. A vent kit, an additional air intake, a can for weight savings and cool sound - otherwise just a proper set up is all the xp needs to totally rip.

I am also very interested in how to make this sled carve and roll over better. guys that say that xp's roll over better than m8's are high. I have yet to experence this. Dont get me wrong I love my xp for its ergos, look, and POWER (which the m never had), but I dont think it rolls over or carves better than a m sled, jmo. Every time i get off my sled and get on a m sled I fall off of it b/c it rolls over so easy compared to my xp. I have gone to rear two wheel kit, moved the bars around, and disconnected the sway bar, and its really not any easier.

Does using drop brackets for the skid help? I know doo went to a longer front shock in 2010, to "help" the sled roll over easier.

shocks? 15" track?


what WILL make this sled roll over better?

Could you please let me know what a roosterbuilt is.The track speed on my 163xp is hard to keep consistant.Changed helix and geared it down.It helped but was still not perfect.Had to go from 4 to 5 on my clickers.Thanks Doc

I have the Hill Climb Edition with the 4 wheel axel and the wide front end. I put the quick disconnect on the sway bar and have no problem sidhilling or carving the powder. My personal thought is the sway bar on the XP is WAY to stiff.

Agreed. The best and cheapest handling mod is to simply remove the swaybar. Stiffen up your front shocks though.

Rolling over the XP takes techic, you should be able to turn as tight as any other sled of the same length, side hill or spin a donut with a stock XP, no problem, save your money.

How ever it's my opinion that if the snow is shallow or hard the Artic Cats and Nytros are easier. I know guys that just plain don't like how the Ski Doos handle but, my opinion is that it's all in ones head.

If you want to lay your sled over and burn a donut try this simotaniosly:

Stand with your feet a little ahead of or close to middle (your size and snow conditions may vary this) hit the throttle, counter steer, pull it over and as soon as you get it starting to roll over, quickly couch down with shifting you feet and lean into it and commit and keep it pinned. Hang on and ride it like you stole it, it's all about balance!

Two week ends ago I taught a 50+ year old guy and his daughter to burn donuts in 20 minutes.

If you think you can do it, you will, don't give up.

Good luck, Will.

will
03-21-2009, 11:11 PM
Oh I forgot, take your sway bar off but, once you get this techic down you should be able to roll it over and do donuts with it on but hang on because if you screw it up it will spit you off forcefully.

Here's a list of mods I did on mine to produce one hell of a sled.
- Throw sway bar in trash, or use it for a clutch alignment tool
- Remove useless plastic under hood and place tool kit under seat
- Fox floats up front
- Nextech fox float kit for rear to ditch springs
- Remove the four idler wheels from rear skid
- Inside wheel kit
- HPS Silencer

This sled is for sale btw . . . I found one I like better:beer;

Just get rid of the T-stat, and put a couple pvc T/elbows to replace. I removed mine, and my temps are around 90-100 degrees in powder. On the trail i am running around 100-140 degrees. My temps never drop below 90 and never get higher than 140. Save your money and just get rid of the T-stat altogether. My machine runs flawlessly with this simle cheap mod.

Any sled will carve nice in 3 feet of snow. Granted some will get stuck more than others. I think most guys complain about laying it over when the snow isn't so deep.

yes the xp is 154 is not a trail sled.......it comes to life in deep powder. it at times this week feels like it gets itself in a tractor gear and just plows its like nothing can stop it...

I don't own an XP, but had the pleasure of ridding a buds a couple times this year. I know exactly what you mean. His is only a 146" and it climbs like a billy goat and works through the deep effortlessly. I'm still on a ZX chassis and get stuck on flat ground!! Anyone want to donate some money for an upgrade?
