I Thought Maybe The Guy I Bought It From Had Old Fuel In Bike. Third Tank Through It And It Is Not Clearing Up. Not Too Bad, Just A Hic Up In Power Once In A While. Any Idea??

throttle position sensor trying to choose the right mapping at low rpm cruising.

The stutter feeling can be jetted out about 80%, but it is just the way the bike is.

Or, if you've adjusted the TPS per the manual and are happy with your jetting, but still having the hesitations, try disconnecting the TPS. Lots of people find that to be a good solution. Search TPS in this forum. BTW, Indy's jetting table is a good place to start.
