'03 919, I went with the standard bars instead of the conicals. I was concerned about the riser adapters. Too chuncky, too many pieces. PJ confirmed that the conicals might be overkill and that settled it. The vibrations are gone. The rizoma bar ends on the stock bars will deffinitely not make you happy. With your hands off the grips, like at a stop light, the brake/clutch handles shake wildly and mirrors blur.
Sorry it took so long to respond - long hours - no sleep.
