I have tried to ether it when it would act up, straight into the air box, no dice... Gonna pull the valve cover today and get the feeler gauges out. Then I am gonna go warm it up without the side plastics off, and try to get it to act up. If it will, try grounding a new spark plug to see if it's a spark issue I am having... Does that seem logical? (Really starting to get frustrated with this thing)
