Not so comfortable after few hours

[ryanschillinger_imp]

So my last couple bikes have been cruisers and I was getting tired of the feet forward position. Really loved the idea of the cb1100 since it came out here. I've been doing a lot of commuting on the bike without noticing much discomfort, but spent a lot more time in the saddle yesterday. Noticed a kind of burning pain in my left shoulder, like on the back side. Also butt was getting pretty tired. What position needs to be adjusted to help with the shoulder pain? Bars too close? Too far? I have the levers set so my hands fall naturally to them and everything. Maybe I'm just not used to this riding position yet.
