I'll respectfully disagree. I've used Stabil religiously in all my bikes, atv's, lawn tractors and other small engines for nearly 20 years. They have always started and ran fine 6+ months later. My ex-father in law refused to listen to that advice. He was a chemist and thought he knew best. Every spring he was taking his lawn equipment to the shop because it either wouldn't start or would run for crap because the carb was all gummed/varnished up. I had a bike a few years back that I had not ridden 2-1/2 years. When I parked it, I filled the tank, added stabil and pulled the battery. 2-1/2 years later, it started right up and ran without any issues just like it did when I parked it. Do what you want, but I swear by it.
