who still is rockin an m7

[high time]

You guys need my Powerclaw

It would make the M-7 climb better. 153 x 2.25 for $400 in great shape.

Guilty! After a powerclaw and the 09 tunnel update a few years back it felt like a new sled. Motor is stock except HPS can. Love my M7 but I'm thinking of letting her go after this season for something new or newer.

I have had this problem a few times with my m7's. And having it right now with my 05. Every time its been a bad servo motor.
If I take servo motor off my 06 put on 05 problem goes away and the cables are same adjustment. Vise versa. Problem follows the servo motor. Couple times I have taken motor apart and cleaned armature and got it to work for half season. But soon as it gets wet it comes back.
I didn't like how my 06 m7 with m8 pistons, 4mmstroker and Twins ran with bdx block off plates. Didn't recover in trees as well when you chop throttle loose track speed and then nail it again it was lazy and struggled to back shift. If I increased rear spring back shift was better but I lost track speed. So went back to power valves.

Thanks TNT7-- I am still suspect of the servo motor, still working toward cable settings, but shape they are in replacement is very likely, if I can find a new servo mo priced right will grab that also- peace of mind and square one set up, then ride the pizz out of it.

DP that is a great looking ride!

Long live the M7!

Sold my 2006 M7 3 years ago, from the box to 2,600 miles not a single issue, loved the sled.

Looking at picking up a 2006 with an OVS turbo set up. Any insight/suggestions/experiences would be awesome.

Just a short vid of my M7 from yesterday.

I sold a couple sleds and bought a snowbike. Now, I only have three sleds for our "family" snowmobile rides. I have been thinking about getting another sled so our whole family of four are on snowmobiles.

I have a M8 and a M5 and a 99 Yamaha Phazer 500. I am looking for another sled to fill in the whole in my fleet. The sleds I have looked at are:

M6
M7
04 Yamaha Mountain Viper
Polaris 550 RMK
Polaris 600 RMK
Polaris 700 RMK


I do love the sound of Yamaha triples but, the ride of the Mountain Maxes just didn't cut it. I think a M6 or M7 would be the best but, what do you guys think?

It's hard to beat the relaibilty of the Gen II and Edge RMKs but the M is such an improved chassis and almost as reliable I'd go for another M. Besides then you got mostly the same sleds.
I'm in the same boat as you and with both kids riding, it's a 4 machine deal just to get on the trail, so the best sled is the one you gas n go. Price being a huge factor, I am not really brand loyal either .Got 2 cats, 2 poos, a doo and a Yami snobike.
My little kids ride the crap out of the old chassis sleds, like S2000 doo, genII pol and a 1980 Cat, but that said, they much prefer the ease of driving n handling of the M or Pro.
Oh and the wife's M7 is hugging 3k mi now, not exactly sure since the speedo just took a schitt recently. Longest lasting cat speedo I've had though lol. It's all orig, lots of miles towing a heavy Sno coach combined with being backup sled for buddies etc. it's still very reliable and I wouldn't hesitate taking it anywhere.

the lack of reliability in a Gen II is what made me jump ship from poo in '06 to my m7, riding the m7 for the past 8 years is why i stuck with cat when i finally updated last year.

I just finished this old m7 for a friend.
It's got m8 Pistons with a Twisted Turbo 2876 with a Boost It fuel box.
New m8 clutches,162 3" track and a bunch of other mods and upgrades.

I went for a test rip on this sled a couple of nights ago,it was -25 c outside so only went for five minutes or so.
Sled ran excellent.
A/F was at 11.7 at WOT.
Best part is I never touched the Boost It box,ran it with the numbers that Neil put in it.
Next week we plan on taking it out to Revy for a final tune.
Twisted Turbo and Boost It rocks!

[broz2006]

I have one. Runs strong,custom tunnel,fox floats, fabtec A-arms, rktek head and clutching

 

[bakininthesun]

Still Running 4 m7 sleds one has 6000 miles not issues same top end

 

[dp2826]

That's awesome. Why can't we get this reliability out of all the new sleds? One of the main reasons I haven't got a new one yet.

 

[Frostbite]

I agree, it's tough to beat an M sled for comfort and reliability. So, I have an M5 an a M8 already. I would like a 153" M6 or a M7.

Is there a good reason to buy one over the other?

Since they built them longer, I can find a little newer M6 than M7.

Is 06 the first year for fuel injection for the M7?

Were there any chassis or engine up grades done to either of these two sleds to point me at a specific year and model?

 

[dp2826]

05 was the first year of the M7 and they also had efi. It's harder to find a carbed M7 than efi. The 05 was a bit lighter than the 06. I had both an 05 and 06. Still have the 05. If you get it clutched right it will hang with any M8.

Well I got lucky with my 01 RMK 800 mod. Over 3k miles with zero engine issues except for a bad coolant temp sensor that left me sitting at the trailhead one day. Carried a spare after that and it never happened again lol.
It always had good crank runout and the guy I sold it to still hadn't cracked it open 2 years later, last I saw the sled.
The 700s on down to the Trail were IMO some of the most bulletproof sleds made to date. I had a buddy with a mod 99 700 RMK who beat the schitt out of it, stored outside, very little maint. Replaced 2 bent tunnels on that thing, but over 4 k Mi on it, it was still running on original internals.

I'd still take a M over a Gen II though.

That's true. Factory clutching was not good. Ran my wife's M7 that way for years because she didn't want it to be any "faster" lol. Finally clutched it with Racinstation parts when we moved down to low altitude and it was a whole new machine!
I'd still ride that sled all day long today and be happy about it!

The reason to get the 7 over the 6 is about 20hp if that's what you're after, otherwise, same sled.
With the 6, 09-11 models will get you the rest of the chassis upgrades, better tunnel and boards, engine reverse and 10-11 models have the good hi rise seat.
IMO it will be easier to find a lower mile M6 that has not been thrashed. FWIW I'd take an 07-08 too, for less than a 09-up of course , especially the 08 with better boards and Float rear suspension, even WITH the gear case reverse. I had good luck with my 08 M1000 Diamond Drive for 2k miles. That mod 1000 tore up a lot of things, motor mounts, primary clutch exploded, parts/ wires vibrated loose or bare and I was always waiting for the DD to explode and it never did. Just changed the oil in it regularly. Never opened up the DD.

What are you running for clutching, if you don't mind sharing?

I'd still take a M over a Gen II though.

My genII was also a '99 700. 3 pistons, crank bearings, then snapped crank, put new crank in and shortly after fried a piston again all before 2500 miles. Musta been a Friday build, I was always told the poo 700 were bulletproof but after that and my bros 02 700 losing a crank it was hard to believe.

Ditched poo for an m7 and never looked back, 4600 miles on stock internals and still goin strong. Do have to replace the primary about every 2500 miles but that's not bad.

05 were all efi and came with the attack 20 track, they were mapped a bit richer which sometimes allows the use of pipes with no fuel box. 06 they added the carb'd option and also the option for the challenger track instead of the A20, other than that it was just little refinements like pins and latches to keep the seat and panels from falling off. Just thought I'd throw that bit of info out there, oh and if you find a deal on a carb'd one don't hesitate to buy it. Lotsa folks are afraid of them for some reason but they run awesome. Mine is carb'd and I've rode for years with 2 efi m7s and mine has always ran the most consistent, I've never had any of the bogs or any of the other little nitpicky things the efi ones are known for. Only downfall I've seen with my carb'd sled is a little stiffer throttle pull.

Parted with mine a few years ago with 6500ish miles. Had it upgraded to basically a 09+ M with a 700 in it. Ran into the guy that bought it a few weeks ago and he hadn't had to do a thing to it and commented how it was the most reliable sled in his stable of 4. Great sleds.
