Dude.... Seriously, My bike is lowered 2 inches also and I have no trouble getting it up at just about any speed. I think you just need to learn your bike.
I used to think that it was all my bikes fault too till I really started paying attention to details like, throttle position - I used to crank the throttle wide open or so I thought, but once I started paying attention, I found that I had more throttle than my wrist would turn.
I had to grip the throttle in a different position to get "FULL" throttle.
You can raise your bike up and shave your seat, but you won't like the feel of the seat. Just practice some more, you'll get it!
