If you do not have DPM, it's a 50. If you foul plugs real fast at low speed, change to a 45 and it will clear it right up. You might want to increase your main jet to a 320 if you do change the pilot. Good Luck. If you have DPM, I have no idea!

I droped mine to a 45 and lowered the needle 1 clip. This cleaned it up and improved mileage by 2. Left the stock jets [310's] and good so far at -10 WOT.

Mikadoo and I agree! Drop to 45s if needed. I didn't bother with the needle clip as the 45s did the trick, plus its less work!!! Good Luck!
