SLP issue or Polaris issue?

[MBR44]

I have a long story so here is the short end of it. New sks, love it, let my buddy ride it and immediately hit a tree causing $8k in damage. Well they didn't total it so they fixed the bulkhead and of course a-arms are on back order so Ean at KoolmeyKustoms.com fixed me up with a set of 36" zbros arms and exit shocks. Couldn't be happier with the sled now. Ride in the UP of MI and this year sucks but still ridable. After the accident I threw a check engine light and figured it was from the smashed exhaust sensor. I picked the sled back up from the dealer and within 2 miles I threw the same check engine light which limits the rpm to 6600. I stopped it and restarted it and it ran fine. I went to the UP and rode for the weekend but it happened 2 more times. Easy restart and off I go. I then went back this weekend and it got worse Friday happening frequently. Saturday it went into shut down, wouldn't idle with out throttle, hard to start. I figured out how to read the codes and it gave me a 520 194 -7. This is the sensor for stuck throttle. I ended up getting home but it would only pull 78-7900 rpm at wot vs 8250 without the check engine light on. I was not snappy up top, almost like the power valves weren't opening. I figured the code had something to do with the tps? I took it to the dealer. They recorded and cleared the codes now. They can get it to go into check engine which retards the motor back to 6600 rpm every time but now it wont throw a code. They got the stuck throttle code but now even plugged in with the light for the check engine on it won't read a code. So they emailed Polaris and they want the pipe off. They could tell from the report sent from the accident I had a pipe on it. I am off to take them the stock pipe and remove the resistor to check for more problems. Anyone have this problem. Seems more tps than pipe issue. I have never seen a deto light from the pipe. I have 17.5 hours on it.

Never bring a sled to the dealership with a pipe on it..

They had all the reports even when it was smashed that had the pipe on it. So it is no surprise at this point.

What he said.

Take the resistor off. Read on here and other places the resistor is garbage and can cause cel's. I'm running my slp pipe and Ggb can in the UP, no resistor, 91oct fuel in eth setting with no problem. No cel, no det. Pulled 8450 all weekend.

This. I hear SLP is working on an updated one or has one.

Plugs are dark brown as well.

Kinda tough to take a smashed up sled into the dealer but the pipe is brand new untouched...

What weights are you running and how many Grams for the UP??

I'm running mds weights. Comes out at 72 grams, might add a little more tip weight. Running 6.8gram in the center and 5.7 at the tip right now. I'm still running a little oil in he has too. Only have 8ish hours on mine

The slp pipe had a dent in it so I didn't want to take it off cause ins paid for a new one.

I am running indy dan helix in the low elevation and his adjustable weights, same profile as the 11 series Polaris weight. I am running 77g. I was at 8250 but since the codes could only pull 78-7900 on the trail/road. My buddy also has a sks, ssi pipe mod and can Dalton weights 10 series profile with stock 40 straight. He has a 2.4 and I have a 2.6, we are dead even in a race. He was deto all the time above 8000 rpm. Eric made him a resistor but it fell apart before he even put it on. He just remade it and hasn't had problems

LOL, that video looks like the exact area we are riding, even those 3 tracks at the end could have been ours. I rode pine stump area the last 2 weekends but the snow is marginal. We mostly just bopp around hitting logging trails like what your were on and trying to find some bowls and hills to climb. That area is tough because the trees are thick. If they cleared out all the 4" and under it would be a play ground. A-arms get a workout, cracked my Polaris bumper last weekend too. The sled definitely doesn't look new any longer. We have a spot on the gps and just ride though the trees to we hit that spot. Found some cool areas along the 2 hearted river and the taquaminon river last weekend.

Where are you riding? We have our week long trip next weekend in big bay. I spoke with another buddy and he is running without the resistor because of codes too. Seems easy slp problem to me. I stopped at the dealer and told them to run it without the resistor before swapping the pipe and clutching. If they get the check engine light without a code then I have bigger issues than a resistor.

That video is just south of South Range.

Pulled the resistor, no more problems.

what resistor are you talking about pulling off?

 

[XC500mod]

The slp pipe comes with a resistor to run at low elevation, you don't need it above 5,000 feet. It turns out the resistor (a little black plug) is not needed at low elevation. All you have to do is run the sled in ethanol mode because it delivers ~4-5% more fuel. I once read that the resistor tricks the sled into giving 4-5% more fuel. So you don't need the resistor, just run in ethanol mode.

 

[rrjames]

Like others have said, if your above 5000 ft(or the bulk of your riding is and you can behave at lower elevation) ditch the resistor and just run it in 91non.

I personally have never seen a code with my sled running this way and pull 8350 all day.
