Recently picked this bike up, got it for a steal and couldn't pass it up. Filled it up with 91, ran fine, filled it up with another stores gas and it started to bog and cut out unles I had the throttle wide open. Any idea what the issue could be? Dirty injector? Dirty fuel filter? Bad spark plug?

I'd suggest starting with a new fuel filter. The 09's didn't have a good design & were known for getting clogged. The 10 model got a revised one. I believe if you buy a new one it supersedes the 09 oem fuel filter to a 10 version.
