Please forgive if this is a silly question, but this is my first motorcycle. After I ride, I pull into our garage (enclosed) and turn off the bike. I find that I have had to start leaving the windows cracked, because the gasoline/exhaust smell lingers for quite a long time. For example, I rode my bike and came home a but before 5 pm. And my garage still smells like a mix of gasoline and exhaust. Is that normal? Thanks.
