So, it's been idleing fine up untill a few weeks ago. Drops down to 1200 and then stalls. I went on a good highway run to get it nice and hot and pulled into the gas station. Got gas, checked the oil, and went to adjust the idle speed. I adjusted it to right at 1500 and rode away. When I can to a stop, idle was at 2200+! I don't know what is causing this or what to do. I went and adjusted it at my next stop and haven't started it again yet. Any ideas?
