I just bought a used 2000 R6 after idling for a while or a quick hard ride a smell of funky feet comes from the bike. I plan on getting the carbs synched and a tuneup. Do you guys have any idea on what could be making this smell? Also if the bike is in neutral and the bike is revved there is a little hesitation then it revs. Any help would be appreciated before i bring the bike to get tuned up.
