If it's lower back and shoulder ache mate, you need to go the other way! Too much weight through your back makes you ache, and sitting further upright will make it more so. If your stomach/arms were aching then you would need to raise it up, but sounds to me as though you could do with flatter bars!
I've always noticed on upright bikes that I tend to get lower back ache on longer rides, on very sporty bikes (daytona 675 for example) around town my wrists ache after a little while, but on sporty, but not overtly so (ZX9R, ZX12R, Sprint 1050) I find the perfect balance between weight on my ass, wrists and back, and nothing ends up aching!
