I got on the bike today for 0.1 miles just to roll the tires. I had it winterized w/ Fuel Stabil and the battery tender jr. The battery starts better than before! However, there is white smoke out of the exhaust when I rev it up a bit and it smells kinda funny. Even after I parked the bike and turned it off, there was still some white smoke coming out! Is this normal? TIA!
