2013 XM getting ready for winter

[lsone]

Near the end of last season I put a MBRP race can on my 13. Has roosterbuilt clutching/gearing and a race can. After I put the MBRP can on, I noticed a lack of throttle response when wacking the throttle from out of the hole, Like the sled would cough/sputter. But would clean up once you got out of the throttle and back into it.. Im planning on wrapping the EGT probe with tinfoil to ensure it seals as well as new exhaust donuts. The sled has 1500km on it. Should I be looking at Reeds? Reason I ask is when it had a TSS can on it, when letting off the throttle it would back fire(easiest way to explain it and the reason why I got rid of it, hated the sound too) and thinking maybe chipped reed?

Thanks.

I cant answer the reeds part of the question. but I did also have a tss can and mine had not quite a backfire but something similar when wide open and let off completely. I do know that in order to put a can on these sleds you need to dealr to go in with their computer and do some sort of flash. They did that to mine before I left the dealer with it. hope this helps

A lot of Etec's don't like MBRP cans (realistically it's probably variance with the cans not the sleds). Try the stock muffler and see if it cleans it up. If it does then try a better can like an HPS or SLP etc.

I don't seem to have a problem on my '15 summit with an MBRP trail can.

The issue on most aftermarket cans is the EGT probe sticks right into the hottest exhaust gas discharge. Use a bushing to bring the probe up higher. When I first installed my Bikeman can, same sputtering issues. Bought their billet extention and did the trick.

What he said above. Mbrp have been hit or miss too. Not sure about TSS. Try it with your stock muffler then you'll know.

does your race can have this extension on where the p[robe goes? this is for my 16 and the can is brand new.

We noticed a lot of the 13 were famous for that little "back fire" with different cans. Spacing the probe back seem to help.

I really appreciate the input guys! No my MBRP can did not come with the extension. I will have to track one down and give it a try. I bought the sled with the TSS can(sold it now) and do not have a stock muffler to throw on. I don't want to do reeds if I dont have to. Not that dragging the rear flap doing wheelies is good comparison but its rather upsetting when a 154 cant with a 163 next to him flipping over backwards lol. Clearing up this bog should solve that.

In my experience it is typically not the can it was engine loading. We found by change the engagement from 3800 to 35/3600rpm it got rid of the stumble and backfire.

Also till u get up top, keep it on clicker one

Half the bog-backfire is the fuel injection going from one map to the other

Kuster showed me this, and I use it now

Also makes close to 50 km a tank more

 

[oler1234]

^^^^ is exactly what it is

the engine rpm is accelerator faster than the injectors can process and there is a hole is the mapping at this point. As noted load it with clickers or what we have done by lowering the engagement.

The '13 MBRP race can I have is different compared to their new cans. The EGT port is longer on the newer cans & I believe that it needs to be 35mm long o/all to run right (I'd have to check my notes at home). The older sleds only had problems when the sensor was too hot, but new programming now also senses if it's too cold, so making the port really long can cause problems also. It used to be common practice to push the sensor away from the pipe with extensions, but now it needs to be in the right spot to run correctly.

Instead of finding the right length extension for my 2013 can going onto a 2015 sled, I cut and tig welded a new port back on at the correct length and have had zero problems. Before spending $$ on an extension, check your port length - may not need it depending on which can you are using.

Soooo where do I find out the length I should have?? Also, should I take the sled in and have any programming done? Its been into the dealer but only for the grips and 2014 oil tank(as I didn't like the BRP recall fix)
