Did anyone out there ever figure out why the 08 & 09 1000's had bogging issues on the bottom end.My sled happens to be one that has issues, 09 M1000 with slp pipe,manifold & can with bd box and kaso dual egt sensor.I notice cat has a recall in gegards to some heat sheilds around certain parts of the motor not sure if this is helping or not, seem like a fuel issue to me played around with mine quite a bit seemed to be getting a little better but it is still there, would a fuel pressure guage help to see if its to high or to little what would be the proper pressure i have heard numbers from 42lbs to 53lbs any info would be great.Also been reading post about DD larger bearing, I am going to bring it to my dealer to have them replace this and any other recalls there may be.Any recomendations before i go just trying to limit my problems this year.

The 09 comes rich out of the crate. As soon as you add any pipe setup to it the sensors pick it up and add fuel. You need to get a fuel pressure regulator and dial it back a lil bit. I run mine at 38 psi with a D&D y-pipe/pipe/can combo. Run egts and youll see how fat and rich they have it.
I do run the koso dual sensor egt i havent seen it over 1300 even after a hard pull, but what i do notice quite often that when i am running on the trail one side will read 400-500 degress and the other can read as high as 1100 when i see this i nail the throttle and low and behold thre is a bog every time so i snap the throttle a few times or just run it at one throttle posistion for about 30 seconds egts come back to within 50 degress and its normal again when both sides read within 50 degress of each other it goes like a rapped ape, the big problem is when the guys what to boondock my sled 9 times out of 10 runs like **** always bogs and when it does i look at my guage and sure enough the temps from one side to the other vary about 500 degress until the temps get closer im screwed. Once in a while it will do it just before i go for climb so i have to turn out before im commited or i would end up with a bundle of arctic crunch to say the least it sucks, but when its on it best behavior i love it which is 1/2 the time so in the mean time i'll keep trouble shooting.As in for the fuel reg & guage which one would you guys reccomed, I forgot to mention it is the 09 sp ltd edition don't no if this makes any diff.

Bog on M1000
The first thing that I did on my 09 M1000 snopro is to junk the boondocker box and go with the DynoJet Power Commander box instead. You can get them from SLP and have them load a program that they have been working on just for the 09 M1000 that I havent had to touch anything on it yet and it runs every time wthout having to change numbers around like I had to do on my Boondocker box every single ride it was different.

I just checked the slp site is it the Power commander 3 for $359.00 if this is all it takes to solve the issue im in,Thanx for the info."Has anyone else tried this box on there 09 sp".
I'm running the pc3 and I still have the bog. I'm wondering if the clutching can have anything to do with it. Like maybe too much load for helix angle or something. What are u running for a helix?
I have the same setup as you, but with the PCIII and bdx intake, haven't got much miles on it but seems very snappy, hasn't bogged yet. The bearing you heard about is an update, if you gear down, which you should imho, BDX will install the bearings on the gears for you, makes the change very easy.

My 07 is exactly the same way. Acts like it drops a cylinder and it runs cold. Then when you get on it, about 90% of the time mine picks it up, but sometimes it will bog. The only way out of it is to back all the way out and start over again. I think what causes the bog is the extra rich fuel curve Arctic Cat has in the program for when the power valves open. So if you have one cylinder that isn't hitting then you rev the motor hard enough to open the power valves it instantly adds more fuel causing a major bog.
The other problem is the sled runs really lean prior to the power valves opening up. So with a box I have been adding fuel to keep this mid range/prior to PV opening up cooled down. Well this adds 6-8 points of fuel. Sure that cools this down. But again the damn power valves open and it is pig fat and falls on it's face. So long story short, you can't just tune out the lean spot and have the curve right after the valves open with the standard BD program because the valve never open at a set RPM range and of course BD uses RPM ranges for tuning. So I hooked up the Servo control wire to the nitrous control on my BD box. This will add fuel prior to the Power Valves opening then cut it the instant the PV's open, Hopefully this will work. Otherwise I am like you and looking for something else. Major pain in the A$$.
Good luck and lets see what others have done here.

every sled's different, a little...my 09 has a speedwerx y-pipe, stock pipe and aftermarket can, with big air intake, modified air box for more air....at 5000 rpms my settings are -2 -3 -2, and 6500 -1 -2 0....i have no bog at all, either before or after valve opening....no burndowns, and i use the 6000-6500 rpm area alot....i arrived at my fuel settings by deliberately adding too much fuel until it bogged and gagged, then leaned it out until it ran, watching egts all the time...after it ran clean, i checked plug readings and correlated that with egts....i tried the sw pipe and stock pipe back and forth several times and concluded the stock pipe just plain ran better....on the dyno, i only lost 1.2 hp on the top end, which i gladly sacrificed for the overall better running of the stock pipe...as i stated in another thread, not bashing sw, but these are the results of my setup....
Clutching???
I just took my sled to the local dealer for a once over prior to the season. I fought with the bog most of last year and thought fuel, but no matter what I set my Boondocker to, it would still bog.
When the mechanic went over my sled he found one of the MTX weights had come loose and shifted over in the primary. I haven't tried the sled yet this year (will on Saturday) but I'm guessing and hoping that is the problem solved.

Is there a re flash for the 09 1000 if so has anyone got it done and did it work.There sure are allot of different opinions and ideas in regards to the infamous bog you would think by now with all the problems people have been having it would be a simple fix without having to go buy 2 & 3 of everything out there on the market to figure out cats f_ _ _ up.Cat should figure this out if they want to keep there customers happy without us they wouldn't be worth ****.Sorry but I'm pissed trying to figure this out.It's pretty bad when all the local dealers don't even no how to fix this i guess i wait until there is a solution.Thanks for all the replies, I am reading each post carefully and hopefully by the time I'm ready to go beat on this sled in a few weeks I will be able to solve it on my own with everyone's help.

One of the other topics brought up that they thought the bog was caused by the oil pump sticking. I have not had the problem myself. I have SLP pipe kit, BD box, BDX intake, RKT clutch kit.
BTW- New power Commander V will fix most tuning ills. Has AUTO TUNE. Set O2 % and it will make all adjustments needed. After 15 mins of varried throttle it will make a map.

my 08 always had a lean bog at 1/4-1/3 throttle....bdx intake, sw exhaust.
added 2 pts w/ PL controller in the bottom, 2 pts at mid and 2,3 on top. bog 90% better
did the 09 flash: now new bog/sputter at 1/4-1/3 position
removed fuel in the bottom, +0,1 pts in bottom, 1,2 pts at mid, 2 pts on top.
now runs like an ape.....again...i dont have a pressure regulator, but assume i'm running to much stock presssure, 44-48psi, so as recommended I shaved the entire map with -2 pts to offset the psi.

so you run a pc v and it makes all adjustments needed,and it made a map!!!!
I talked to slp about the PC V and they said it's more oriented for the 4 strokers.

Need more informatoin on this PC V. Would love to see that.

I thought the PC -5 was not out yet for the 2 strokes, I heard they were still testing. If it is avaliable I will be purchasing one.
Mine does the same thing on my 08 with Sw can, pipe, and BD box. I was going nuts last Spring trying to dial it in. On the same day with the same conditions it can run great for 2 hours then randomly start doing this and my EGT's show the same as you like one cylinder is dead.
