M7 died. Help point me in the right direction.

[mountaincat 800]

'06 M7. I was cutting a nice sidehill and it just flat quit on me. I thought I burned a piston or something but I still had good compression but it would'nt start. After waiting for the rest of my group to catch up to me about 10 to 15 min. it fired back up. Took off down the hill about 200 yards it died again. I could let it sit for a few minutes and fire it back up and go another 200 yards not running great but running. I think that its probably something elrctrical so just curious if anyone else has had a similar issue. My pull starter came off ealier that day and I had to bolt it back on and the sled has been spitting and spuddering on top end for the last few rides. Any suggestions? Thanks

Could be the fuel pump. I had to replace the pump on my 05 m7 at the start of the season. Another 05 in our group went out shortly after mine did also.

Is it only quitting when you are at full throtle?

My 05 M7 had a short in the tail light that made it run really bad. Mine never shut off completly, but I didn't ride too far before turning back. That might be what it is. When it does this the gauges don't work and the headlight flashed.

make sure all your plugs are dry and tight....could be a motor issue as well. a buddies m1000 was doing the same thing and he cooked one of his pistons

stator

 

[scotty mac]

I own a sled rental I have lots of pull cord failures replace stator they are expensive get it rewound half the cost You will need a fly wheel puller buy it change your self easy as pie. If you have a puller cost is around $250 rewound go to a dealer $800 stator causes all sorts of weird problems test if you can both sides of phase

check the ground under the colant bottle

cpa it will quit any time idle, mid or full.

mr08 Ive checked that wire on the tail light, not it.

Clark Im gonna have to check out the motor but Im leaning toward what scotty said in it being the stator. Now at home running in the drive way it only runs for a minute or two then quits. The motor cant be getting hot but something might be shorting in the stator coils. I need to find someone in Utah with a spare that I can switch out and see if thats it.

By the way goliath the ground is tight.
Thanks for all of your suggestions. Anyone thinking coil or ECM?

 

[mountaincat 800]

Scotty can you explain how to test the stator?

 

[mountaincat 800]

Ok ive had a chance to look at the pistons through the exaust ports. I cant see anything that looks bad. I pulled the flywheel and didnt find anything in the ststor either.

Cpa when your fuel pump crapped out could you still fire up the sled and than it would quit? Thanks.

I know it's the stator, mine had a top end miss/sputter and it was getting worse, pulled flywheel stator looked perfect. ....??... I took stator off and barely seen a LITTLE BIT of rusty powder around a winding on the BACK SIDE and found winding was a little loose on pole, put spare in I had laying around and away I went, runs perfect.....it's the stator, look closer.

Might be ECU. I had a bad one once.
The machine would run till it got warm and die. Let it sit a while and it would go some more, and die.
Would run good till it warmed up.
That would be easy to check.
Good Luck

My 05 M7 is doing the exact same thing! At idle I have headlights, dash, tail, etc. When I slowly raise engine speed to around 2500 to 3500 the lights and dash go out and my Boondocker box freezes. If I then start riding it will die within a few sec/min. I'm going to check all of the connections as well as the ground. I have a factory manual and all of those items, as well as the ignition coil, run off of the same winding on the stator. I'll let you know what I find but I'm leaning towards the stator as well. Where can you get them rewound?

my m7 had the same type of deal, check the servo motor for the power valves both the cables on mine fell completely off and kept dying on me every couple hundred feet.

Already went through that earlyer in the season. That problem gives the computer a servo motor failer code. My gauge is not flashing any codes with this failer.

Ok finally got to check the stator. On initial test resistance checked good. I pointed my heat gun at the stator and it soon failed. After a minute or two of cooling it checked good again. Sooo. I need a stator for an '06 M7. New ones are 600 bucks. Anyone got one they want to sale?

M7 Stator

I was stupid and had a new one installed. Right under $1,000.00. I didn't ask for the old stater. Take it off yourself, have it rewound. Also look on E-Bay for a new one. Do it your self and save BIG bucks. Serch the web for someone to rewind it. There are two places if I remember. One back east and one in Canada. Cost is somewhere around $250.

Go to rmstator.com they can fix you up for about $175.00 if they dont have one in stock they can fix yours.
