I would also check your chain tension/slack at various locations by spinning your rear wheel and checking at different points of rotation. Your chain should be adjusted at the tightest point. If you get too much variance in chain tension/slack as you spin your wheel then you may want to look at sprockets.
A large variance in chain tension/slack will transfer to the vibrations to the bars and actually feel like an unbalanced tire.
