M1000 giving me a headache. BOGGING

[WyoBoy1000]

Wow, lot of ideas. I had this happen on the way back to trailer and I went home and cleaned and ajusted my power valves, problem has not returned. I alway run 92 octain. The pipe sensor might be a good place to check as well. Good luck.

checked power valves the day before,
92 octane just means 91 with ethanol. Try to find some 91 w/o ethanol, way better.

Changed my plugs today and found the 2nd coil Ignition wire from the pto side had chaffed right apart. Could be causing it to bog.... 08 m1000

checked plug wires I tied them together in a way they can't rub on objects as I had the wires on my 07 rub through on the head. put new plugs in before this ride as well.

Bog

My 2008 SP is doing the exact same thing as u2celk, I just recently put jaws pipes on and have done all the recommended clutching and am using the bd box like they used during their tuning, I have a timbersled intake and stm valves. I have the exact same bog after pulling hard on the sled and letting off and when I get back into the throttle wants' to die. I use the recommended fuel 91oct. When stock I had a adjustable fuel regulator installed and dropped the fuel pressure to 44psi, the stock reading was 46psi. This is a irritating problem and could get a guy in a bind when after a long climb you need the power back right away. There are allot of variables that can cause these problems, where does a guy start?

My 07 did some funky things back in the day, after a long pull sometimes it would die but then took for ever to get started and then would run fine, shortly after it broke the spider, pipe sensor went out, pv motor quite and i never figured it out, sold the sled after everything was warrantied. I am kinda thinking pipe sensor. I will know more when I ride again as it is still setup (added way more fuel on bottom) till then still guessing.

Has anyone one had this problem and then had the new 09 reflash? If so did the bog still remain? This is one thing I wonder if it is in the ECU programming, maybe it is something you just can not completly get rid of. What a joy it is and as someone said it can and will get you in trouble.
My 07 1000 has fuel regulator running at 43 psi. SLP exhaust set up, the air intake is just stock other than a full opening on the expanded hose. Aftermarket straight 40* helix on secondary with a A/C orange & white spring, and the shift assist bearing. Run the 046 belt, new powervalve cables no problem there. I have changed out the exhaust temp sensor from my M8 that has no problem and the M1000 still has the bog. Attitude box that when I adjust it usually makes things worse, so I feel it is pretty well dialed in. No EGT to really check but have over 2300 miles and the piston wash looks just right. Sled pulls nicely at 7400 RPM and the riding is around 10000'. That is all I can think of to tell about the sled to narrow down a common problem that seems to be out there. I am at a loss for a reason the beast boggs!
Sorry so long but hoping we can find a answer to the problem.

Not to highjack the thread at all but what do the 08 M1000s with the 09 reflash run best on 87 or 91 octane?

Where do you ride? You said yours bogs but then when you let it sit it will run fine for the rest of the day?? Or does it always bog a little. If there is a slight bog always I would try adding lots of fuel on bottom, try jumping your F/P to 46-48psi if that doesn't work then add a bunch with the attitude, if it still doesn't work just try adding with attitude. when i just added a little fuel on bottom it seemed worse but when I added a bunch it got better. I think ? most of the fuel boxes don't adjust below 3000rpm this is why upping fuel pressure could deliver more off bottom.

Stock with or without reflash should be ran on 87, 87 has more bang, 91 just reduces pre detonation, Mine seemed to run well with 89 at 5k.

I was having the same issues with my sled and after we adjusted the oil pump to its proper setting I have not had the issue again

Are you talking about getting the amount of oil used right? Like 40:1 - 38:1
or some other adjustment?

When it bogs, pull the pipe.
See if the y-pipe is wet to one side. IF so, she's over fueling. Any update is probably gonna make it worse.

 

[KAWGRN]

if your snowmobile is mainly stock you could have a faulty oxygen sensor or wiring harness. If so, your computer would have to guess at how much fuel to inject and could throw off the wot or mass airflow sensor causing hesitations/bogging and all that good stuff.

Just a thought,

wtf?????????

 

[mmsports]

My thoughts.

As I read through this and reading what his symptoms are it could be the throttle safety switch just check and make sure you do not have play in cable.

Sounds like a fair amount of people having issues with modified M1000s. I'm seriously considering picking up an '08. Is it possible to run the BDX box and SLP pipe kit and not have a bunch of issues like what's been posted above? Is the M8 less finicky?

Any sled with modds are subject to problems, a few out of hundreds is not much and if that scares you get a 2010 m8 and leave it "stock"(but then you will be changing the primary spring from breaking, trying to get it to engage softer and you might have a bog). Most of use run a variation of mods that don't fit the specific setup from the mod maker, so in other words we are adding or own mods and have to go through the hoops to tune it, I know of many setup per slp's instructions that have never had a problem. I wouldn't trade my m1000 for any thing less. If you want more info on the subject start a thread as this one is for the m1000 bog.

Correct me if I am wrong but the throttle safety switch would cause trouble when you let off the throttle, wouldn't it? Mine acts up when you squeeze the throttle.
Thanks for the input, trying for pefection on M1000 seems to be a full time project.

the saftey switch only works when you push the throttle. So if it is not working and you push the throttle the sled will die, if you feather the throttle you will only get it to 4000rpm and then bog and die. The pin that go's through the throttle block moves and as it moves it pushes in the switch, so if your throttle where to stick and you let off the throttle when the switch disengages and the motor is still above 4000rpm it kills it.

Wyo said it. I had similar problems when I installed a lefty. I got the nut on the flipper too tight. You can check the switch by unplugging it. It is inside the throttle housing, a small black plug with black/red wires

 

[mphfreak]

check and make sure there is no condensation in the barometric sensing tubing line off of your ecu. That can cause overfueling and bogging.

 

[u2celk]

HAHA I finally get home from work so I can start using some of the information I have got here, and what do you know NO reverse.
Pulled Diamond Drive down and bottom half is full of ice, now it is time to wait on seals and bearings.

D&D is back in New York. As far as I know, they don't test at elevation. Octane would be different.

MY 09 M1000 WAS DOING THE SAME THING

TOOK THROTTLE APART AND INSTALLED A SMALL SCREW INTO THE THROTTLE SAFETY SWITCH DISENGAGING IT.
