I bought some bar risers the other day from a guy in the US. He has them made up on a CNC mill to his specs. They are great and cost me $45 US including freight. They are great quality, and he has them in either a straight 1 1/2" rise or an offset rise. Here's a link: http://www.motorcycleproducts.org/bar_risers_ST.html They bolted straight up to the Z, and should fit any bike with the standard 7/8" bars, but he has measurements on his site to check whether they will fit your bike. Just posting because I couldn't find anything decent in bar risers under $150 and I like these ones a lot. Regards, Andrew.
