My 06 model has been running poorly. She feels like starving when idling, bogs like crazy and when cold. This just happened all of a sudden. However I did suspect it could be water in the fuel... Ive just hit reserve and the bike seems to idle better. Now ive come to a couple of conclusions The bike backfires (pops) down long hills Does not idle well. Seems to bog more then usual. So here is what i thought Faulty AIS Diaphrame (bike running lean) Water in Fuel (bike not idling and performing poorly) Valve clearances. Any ideas? Though of running my tank dry and getting fuel from another station... before i rip the head open to inspect.
