I would think you would have better luck to give Bikeman a call and get their input on it, BDX just installs their big bore. 9 psi between the two cylinders is getting pretty borderline to get a fine tune.

I don't believe the 950 is bikeman kit anymore.

Variables in every sled.
fuel pressure
⏹⏺ ECU
Some are just rich
Some have less timing.some more
If you add 100 plus cc and have not added timing
And a bit rich yes you could be fouling plugs.
As for the guy that had a bad stator that can be
Tough to diagnose, did one this year and I was
50/50 if that was the problem. Pretty much a guess.
I don't have a 950 but I'm sure it will run great once
Tuned.
Yes it has a timing key that came with the kit from BDX
I recommend the TPS calibration. I have the BD box but had an issue similar to yours. Once the TPS was dialed in, no problems and runs like a top. Make sure you also check your power valve lengths to make sure they are within spec of one another. This can f things up too.

Ok thanks TPS calibration is my next step when I get home in 2 weeks. Dealer said power valves were checked and were to spec.
Hey there Cory. Feel free to give me a call at the shop to discuss your issue. I was out of town in Iceland for a week and just got back to work today. I'm not sure if you tried to call last week but I didn't have any messages on my desk from you when I returned. You can also email me at erich@speedshopinc.com.
I have a very good map for the 950 models of course, and for all elevations. We have updated several of our Prolite 940 machines to the 950 version.
The TPS can be set using the reading from a Power commander.
****Important***** Voltage for the TPS at Idle with our larger 52mm throttle bodies is .71 volts.
Our phone number is 507.263.2244
I know I can help you out, just need to deal with you directly.
Thanks, Erich

Any resolution on your sled? It'd you get it running properly?
C
One more off the wall fix could be your smart valves in the tank. Mine went to **** and would cause some crazy bog issues. I have the big throttle bodies on my 800 and it was pretty finicky to get tuned but once I got it right they're great. A new smart valve assembly is only about 70$ Google proclimb fuel surge and see if it matches any of your symptoms
C
Ok ythanks I'll look into it
I never heard from you? Give me a call or email so we can help you out.

I'm ready to cut my ties with BDX/SSI I missed nearly all of the 2017 season because of this. I've talked to you and the other guy at the shop I believe his name is Kevin at least 6 times. My local dealership has talked to you several times as well. If you want to be a stand up company and help resolve this problem you can call me. I'm tired of wasting my time for a "man idk what it could be" Cory Florence 406-471-3184
I see you got your kit at the end of February from us to update your burnt down 940. There isn't anyone named Kevin here. Which dealer has been calling who do they say they talk to when they call? There is only Jeff, Ray or I and most likely me if was a technical question. I've been pretty easy to get ahold off unless it was the week I was in Iceland.
Has to be something Cory. If the pistons are fine, and the cylinder walls are fine, and the head is fine, and the exhaust valves are fine, then we need to look at something besides blaming a big bore kit. I have been doing 800, 900, 940 and 950 big bores for since the lay down cat motors came out. And we have a lot of 950's on the snow, they work.
There has to be a gremlin somewhere, and they suck to find sometime. So I understand your pain.
I will give you a call now.

Today Erick from BDX contacted me. He was helpful over the phone. The sled is going to my local dealer and they are going to team up and try to resolve the isssue.

I bought a SSI 950 last spring and put it on my 2017 ProCross and it has ran Awsome!!! Called Eric a few times and he was Very Helpful!!! I ran it on asphalt all summer with great performance. I did find the 17 ECU was much richer than the earlier 2012-2015’s. With a Jaws pipe & stock TB’s I ran 000 # on my Boondocker WOT
How fast was it in the quarter?
M
Im 280 lbs in leathers and I have a extra radiator on the back of my tunnel to keep me cool so I don’t have to use a cool down and electric start and battery still. Me and the sled weights in @ 855 lbs. 10.6 is my best in the 1/4 and 6.6 in the 1/8.
