It finally happened to me. I parked my bike in the sun for about 20 minutes with a full tank of 91 octane Shell gas and when I returned, it took a good 4-5 cranks before it sputtered on. This was in 85F weather. It was kind of embarrassing because a bunch of people were checking out my bike when I walked up to it. How do I take care of this issue without causing harm to the rest of the bike? Will removing the emissions stuff void my warranty?
