Joka, you need either universal mounts or a new top clamp to fit oversize bar mounts. Typically these raise the bars about 10mm or so, but you get more adjustability with some of them. The oversize bars are definitely worth the money and are the only thing I run on 3 race bikes. You might want to check out Tag and Renthal, as both offer oversize bars and Tag offers mounts. In fact, Tag offers a kit that includes everything you need in one package. I sell this stuff, so let me know if you want a price quote.
