2003 GTX 4-Tech with low hours. No running issues at any speed. The issue is how often I have to change the spark plugs ( NGK DCPR83/4339). It will run great with new plugs. Next time try to start, whether that day or more than a week later, it will not even hit. New plugs fix the problem every single time. I have read if you have a no start to change the plugs. And that works. But why? Much worse this year. Literally having to change plugs after every ride. Then starts right up and runs fine until try to ride again. Plugs I pull out look brand new, no fouling, no oil on them. Last week I tried E3 plugs. Went on a 10 minute test ride. Then yesterday would not start. Another new set of NGK today, started and ran fine.
