Motorcycle Repair: 1999 heritage softail, blown head gasket, heritage softail

Question
my bike runs good but at idle has a distinct noise from which seems to be the front cylinder any ideas would be great thanks

Answer
Noises are hard to diagnois on here because I can hear them.
Check around the cylinder, where the head is bolted and see if you can feel air. You might have a blown head gasket. Feel around the exhaust, might have an exhaust leak.
Good luck and happy riding
Mike
