Hey, I took my Banshee out the other day the first time with the PVL ignition and new B9EV plugs. It's really cold (-5 to +10 degrees) was hard to start but when I got it started it ran great. There was snow out and I had the motor at half throttle most of the time. After I parked it for a while, it started then died. I checked the spark and there was spark but it looked weak. After pullstarting it it ran, died, and wouldn't even make a "pop" when we tried to pull start again so I think my plugs are fouled. So should I go down to 8's or 7's on my plugs?
