Interesting, because the frame should be ballpark fine (although verging on the small size) for 6'1". What are the actual bike dimensions (seat tube and top tube centre-to-centre) and how high do you have your saddle (centre of botton-bracket to saddle top)?
For sure the stem and bars may need adjusting. Another possibility is the saddle position, maybe it's too far forward or the stem does not have enough set back? If you move the saddle back, clearly you increase the reach to the bars, but it also enables you to bring the saddle down a bit, because the distance from your hips to your feet has increased with a purely horizontal saddle movement.
Also, where exactly is you back hurting? Shoulders or lower back?
