I Just fouled my second plug and the only thing that I can contribute it to is starting the bike (to show a friend ) and letting it run for only about 30 seconds and turning it off without ever fully warming up. The next time I tried to start it, no fire. Not even a sputter. Put in a new plug and it fired right up. Never fouled one while it was running (yet). Has anyone else seen this particular problem? This is an '01 and otherwise has run flawlessly.
