Doesn't the 06-07 come from the factory with a 16/43. That being the case, that's a huge jump to say 15/47. When I was running an 01 GSXR 600, I went up one tooth on the front and for Pacific I ran a 48 rear sprocket and I dropped it to a 47 for Spokane. Portland and Pacific gearing were pretty much the same for me...someone may have a better set-up, but this maybe a good place to start.
