M1000 lightweight can issues

[xcrider]

This is my first post on this site...see there are a lot of knowledgable folks on here, so with my first post heres one for you.
i just acquired my first cat, an 09 m1000 snopro and right from the get go I had them install a mbrp can on it. i only have 70 miles on it and am noticing a bog 4 times out 5 when I punch it.
i had it back to the dealer and they adjusted the belt deflection and did the first time in service.
I was hoping to see the bog gone, but it is still there. i read somewhere here on this site that certain cans may cause this bog...is this correct? Also it seems to be worse as the machine heats up.When cold it is not near as bad, or if you let it sit a while and allow it to cool,when punched it rips, once good and warm it'll bog. I need to put a smile on my face!!
Has anyone had this sympton with the mbrp or any other can? I will be putting the stock silencer back on to try and rule out the can issue. I'm hoping to be able to still use a lightweight can for weight savings though.
Thanks

try the stock one, but the slp can seems to be the best for all around performance. It also seems like a lean bog, when the sled is cold the ecu tell it to run more fuel, like a choke and then when warm cuts it back a little, it also may be a oil bog as the 09 oiler is tight in the middle causing it to stick and over oils, sometimes How many rides do you have on it, there should be some oil premixed in the tank and will take a few rides to clear it up, also run 87 octane these motors are built with low compression and have better power with 87 over 91, you only need 91 if you add more than a can.

I'm on the second tank of fuel, of which was 87 octane without added oil.
Any other thoughts out there? There must have been other m1000's out there that suffered with the same bogging issues.

Mbrp

I have the same can on my 2009 M1 LE, great sound. I also have a few other mods that are working.
For the bog problem you may want to check the primary weight pin retainer nuts. If one of these are to tight it puts pressure on the rubber O-rings. The O-rings start to grip and won't allow the weights to move freely. I had this happen to mine. Altitude kit, dealer set-up.
Also try removing a .020 shim from the secondary.
The belt deflection may seem alright, but may still be to tight. It doesn't hurt to try and only takes a few minutes. Belts usually last longer this way.

pretty much every m1000 i've herd of has a slight bog in the low end

No more bog on mine since I added the mods which are in my sig.
No fuel controller either.

Not mine, Not my dad's. Both running MBRP cans and fairly stock. I would try it without the can but as said above it sounds like a lean bog.

2009 M1000 Sno Pro Bog

I'm having the same problem, sled bogs after riding about ten minutes after start up. Will only rev up to 6250 RPM and will not rev past 6250 from half throttle to full throttle. When started up after a ten minute rest will pull to 7750 no problem(Pulls like a freight train) ten minutes later bog is back. I think the bog is from over fueling as it only has 50 miles on it and already has burnt over seven gallons of fuel!
Keep the suggestions coming, I would really like to get this solved before we go to Golden next week.
Throttle body icing possibly? Sled is bone stock no mods whatsoever..

 

[killerrf]

running a d&d barker and no bogs. works good.

 

[xcrider]

Prospectus..those are my symptons exactly..The dealer believes its the can and backpressure issues.
I haven't had a chance to put the stocker back on and give it a try, but I have a gut feel it is not that. Same here burning a lot of fuel for the low miles put on. Around 70 miles and almost 2 tanks later.That don't sound right.

xcrider, you may want to check your primary weight pin nuts like 1m62 pointed out. I also have a mbrp can on my x-fire 1000. It had a bog around 6200 rpm. I thought it was the can or possibly the reflash i had done. My sled also over reved, so i added more weight to the primary and noticed the retaining nuts were way to tight. The weights could not swing freely on their own. Once i put the new weights in and tightened the nuts properly, the over reving was gone and so was the bog.

Sounds like I have the same situation. I recently took receipt of a new to me completely stock 09 M1000 with around 600 miles. On my first run last weekend, I noticed while trail and lake running that when I hit around 6200 rpm, the machine would bog badly. After letting off the throttle and hitting it again, the 3 or 4 WOT attempt would allow the machine to pull properly. I don't know much about these machines other than what I'm reading here as I'm coming off a RX1. I'm not much of a wrench but I'll have a look tonight and see if anything obvious looks out of line. I'm only running around 2500' elevation FYI. The machine did seem to be burning a lot of fuel, but coming off the 4 stroke, I realize my consumption will be higher. Also, given my limited tech skills, do you guys think I should stay away from mods and remain stock?

 

[xcrider]

To me if the bog was due to clutching or the can, it would be there all the time, not just once the machine was good and warm.The dealer installed heavier weights right at the start as I ride 2000'.So maybe the weight pin nuts are too tight, however why is the bog not always there,only once warm. If let to cool it will run good, once warm it will bog 4 out of 5 times when punched from a stop.
A dealer said he had this happen to 6 sleds in the recent past. The ecus were sent in for a reflash, those that have come back apperently have the issue resoved. He is dead sure it requires a reflash. i will be removing the ecu and sending it in here shortly.

 

[WyoBoy1000]

because when the sled is cold the ecu give it more fuel to warm it up, like a choke. and then when hot its causing a lean bog.
