I did change to a warmer plug last year but it ran fine rest of the season. Anyway, that's the simplest and cheapest place to start. I'll yank the tank and change the plug tomorrow. But if anyone else has any thoughts feel free to throw them out there.
It is a simple bike, so let's keep it simple. Don't change the plug or pull the tank unless you just like the exercise. It starts and runs, so it isn't the actual gasoline or the plug.
First ask yourself, why does it start and run but then act strange down the road?
Will the bike start in the driveway? If so, then start her up. Let it run until it is hot and
off choke. Let it run a good 5 minutes. Still running?
Let's start there....what happened? What position is the petc0ck in? Do you have an inline fuel filter?
