Hey everybody, just bolted on my hmf exhaust. I started it up, (without jetting it) and i putted around, nothing special. then i got off the bike and revved it a couple of times and i notices that if i revved it high a spark would come out of the exhaust. its an hmf slip on with a silencer. any clue what this might be? ??? the exhaust is sick by the way i totally recommend it. great price with great performance. I'l post pics tomorrow. thanks for the help
