Whatsup y'all, so I've had my 01' St1100 since April and everything has been running great. Changed the oil a two months ago and everything has been good. But as of this week. It's been having an overwhelming smell of exhaust. It happens when I start it up and it sits at idle. Not sure what to do at this point. Doesn't smell like eggs or anything it just smells like A LOT of exhaust. What do I need to do???
