Polaris sks 2016 trouble

Goldo said:

Hey guys ! I need help here . I'v bought an SKS last year and i'm having numerous problem with it. But there's one specific i need help with. The dealer don't have a clue about it. When i play with it in off trail. I'm having something that looks like a bad fuel distribution. Not full throttle. I'm talking 30-40% throttle. The machine is bugging like not the right amount of fuel is distributed. I had a similar problem with a Yamaha raptor i had in the past. And i had to install a power commander and got it setup on a Dyno. I got a GGB mountain Can on it and a LOW altitude clutch kit. If anybody got an idea of what is causing that i would appreciate the help.

Mine started to do this as well after about 1000 miles. It usually happens at ~4800rpm. I haven't pegged what it is, I don't want to deal with a dealer until the end of year.

I changed plugs, used different fuel. I have been told never to touch the exhaust valves but I can't see them being clean...

Does the SKS have the non ethanol fuel setting? Perhaps you are on the non ethanol setting using ethanol blended gas?
I know my assault rmk had a little stutter ever since day one, and it turns out, not every shell has ethanol free premium....Found one that does and stutter went away.

If it stutters at 4880 rpm and you can't pull full RPM you may have the bad relay issue....
