Yes, like a lot of guys, the riding position is the primary reason I initially bought my KLR. Big guy with bad back - that's kind of a familiar refrain around here!!!!
You might try slightly changing the position of the bars in the clamps first. Then aftermarket risers and highway pegs (recommend h'way pegs no matter what).
Then different seats, but that opens up your wallet a lot more than the risers and pegs.
edit - Just a thought - check the preload on your spring - it might be set too high and you're "hardtailing".
