First post here bear with me. I have round 230 miles on mine here lately i have noticed a bit of a exhaust leak after its gets warmed up. Also kinda of a rotten egg kinda smell hard to explain the smell. It only does the smell after a long road ride. 20-30 mph. Not running hard at all. It runs fine and has no check engine lights or anything. Kinda thought maybe batter was overcharging at high rpms but i checked with voltmeter seems to be right where its needs to be. Anybody else has this problem?
