I have a 2017 Polaris rmk pro 800 and it keeps fouling only the clutch side spark plug. Only mods are bikeman billet cooling head and ggb can. Maybe get 10-15 miles a plug. Plugs look rich when pulled. Seems to only foul from low rpm like right when it starts. Just had injectors checked and they are 100% fine. What else can it be? Check oil use and it’s right where it should be. any help is greatly appreciated.

How many miles on the sled?
how is the wire and cap? check the ex valve.. after compression theirs only a few components that run independent to a specific side
^^^^^^^^^^^^
Bikeman tells me it’s because of their head and the fact that in runs too cold. Around 93-95 engine temp. They advised me to run a different spark plug. Can’t remember which one right now. They also were supposed to send me a revised thermostat for their billet head and I never got it. I guess all this will be revisited here in the next month or so. I have not checked reeds .
