The quad runs awesome when it’s cold, just after it gets hot it won’t start up again until it’s cold, these are what I’ve already checked:
  • set valves to the looser side of the specs
  • checked all vacuum lines/wires and plugs
  • battery is good and charged right up, issue still happens even if it’s hooked up to a charger.

I did pull the spark plug out and it’s super white on the tip, I’m wondering since I just installed 490bigbore with the stroker crank if i need more fuel through out my whole map? Not enough fuel possibly causing it not to fire back up when it’s warm?
My tuner is a power commander 3 and also have the ignition module as well.
Any help would be awesome!
