Axys Choking out

[Falcon1772]

Starting my own thread, since my posts on others aren't getting much responses.
So here's the scoop: My axys has been choking intermittently in powder, its usually during a carve and it will just bog for a second and then rips good. Got about 290 miles on it now.

Went out and checked the wires, Ended up putting dielectric grease in every non sealed connector I could find. Found one relay that was pretty corroded green and brown nast all over. Cleaned it up pretty well and greased it, then wrapped rubber tape around it. the relay that was corroded was the one that is taped to the middle bar near the connectors for the exhaust sensor, there was 2 relays taped together. Seemed to help for a little bit but then cut out a few more times today, just real quick bogs.

Any ideas on what to do? Or whats causing this? Took all the plastics off and I inspected every connector and looked at all the wires in the sled I could find, greased the ones that have 0 protection from moisture.

Have you tighten your throttle cable since you owned it?

 

[Falcon1772]

yeah just adjusted it a couple days ago.

First place I'd check for a "quick bog"( is it more like a hiccup?), is clutching.

If it does it in powder (when cranked over and spinning track, or when loading/ unloading track over bumps/ pillows) it could be the soft limiter kicking in.

The rev limiter will kick in in two different instances, straight over rev-- motor spinning in excess of maximum rpm limit, BUT it will also kick in if crank angle sensor reads the crank accelerating faster than parameters in the ECU allow. This feature is designed to save the crank should the belt explode under power and keeps the crank from spinning to the moon.

Easy way to check is to add more weight to the primary-- specifically in the heel or middle portions of an adjustable weight.

Replace the relay.. Tape the both of them so the water doesn't sit on the end of the relay

 

[Falcon1772]

its on my to do list, I've already relocated them, did that when I did the greasing. They're vertical now. and taped up with silicon/rubber tape. just need to replace them I guess

Do you have the stock muffler on it or aftermarket can? I had the exact same thing happen on my 17 when I put on my new HPS can. It would bog only in powder very randomly in the midrange. Bog would last a few seconds until it pulled through it and ran good on top end. Drove me crazy so put the stock muffler back on and never bogged again. I put the HPS can back on to try one more time and same bog. Went back to stock muffler and problem solved no bog.

I have the MBRP Trail can. And mine usually bogs at low speed right when I'm about to initiate a hard carve, So right when the throttle is building. Went on a long trail ride yesterday and it had 0 bog. So maybe it is powder related?

Seal the exhaust outlet to the belly pan

Just got back from a ride. Worst day yet. Going to the dealer tomorrow. Today it would "bog" seemingly whenever it felt like it, moreso when carving left, but would also do it straight, on completely bare parking lot, carving right, starting out. I suspect that somehow my clutch is slipping because I got chucked over the bars about 4 times from it suddenly losing all momentum, as if the belt had broke. I could also feel it vibrating in my left foot when it would do this. When its not doing this its running like a champ. But it put a serious dampener on my ride today.

It was also progressively getting worse through the day, at first it was hiccups, then got to the point where it would be a second or two or more of straight "bog"

Have you tried running it with the stock can? If so does it do the same thing?

 

[Falcon1772]

I've ran it with the stock can before and it never did it with it on it. But I've ran it with the mbrp for longer and it hasnt had issues till the last couple rides.

That sounds like your hitting the DET sensor big time.

Some of the after market cans are real bad for this. Combine that with some poor fuel quality and low elevation and that could be your whole problem. Eric

 

[Falcon1772]

I'm not saying you wrong at all but I'm curious as to why its just now been a problem. What can change? I had no issues last year riding in the same areas, with the MBRP being my only mod, this year its a different story. Same single mod, nothing else has changed other than me putting dielectric in the wiring.

And wouldn't detonation throw a code?

 

[SRXSRULE]

Det doesnt always set or code or turn the check engine light on but it will usually display DE7 on the dash while its happening. Fuel quality plays a big role with these sleds and its easy to get bad gas.

You also mentioned the vibration in your feet. I guess it could be your track ratcheting but normally thats not enough to send you over the bars. Eric

 

[Falcon1772]

See and I thought that it might be the track too, but the tension is good, and we all were running the same gas, 2012 assault, 2007 Summit 600 SDI, and a 2014 skidoo. Only other one having issues was the 2007 Summit, and we think it was the ice caking on the intake. Oh and i did look a few times while it was happening and nothing, just revs around 65-6800

just watched a powermods video on detonation in his AXYS, and he mentioned blowing a plug out being a sign of detonation. I had that happen a couple days ago... I think you guys may be on to something. What can I do to fix detonation? I'm still gonna take it to the dealer, and Im gonna mention all of what I think it may be. I'm also gonna ask that they manually do the TPS.

 

[Falcon1772]

Dealer is closed today. I'll take it in tomorrow and keep you updated.

Mix in av-gas with your fuel should help.

 

[Falcon1772]

Dealer called earlier and said it was done, said my plugs were loose again and that my TPS was indeed out of spec. I'm gonna pick it up tomorrow morning but I'm gonna ask that they put a borescope in each cylinder to make sure that no detonating has occurred. I talked to a friend who flys about using AV gas and he said it's leaded. Is that a problem? Gas I assume that half a tank of our "high octane" 90 and half a tank of the 100octane AV gas will average to 95?
