If you go with a 1 1/8 bar, you're going to need some sort of adapter. Most times the stock controls will fit (the bars are still 7/8" where the grips and controls mount) - you can run into trouble if you try to add a set of handguards since there is very little room left over. You can get some more room by adding a shorty shifter and removing the shifter on the bars. If you go higher, you can get some slack by rerouting the cables.
dixie saw my new setup tonight, ive got rox 2" anti vibe risers and pro taper contour cr mid bends. i havent ridden it since i put them on but they are comfortable just sitting on it. ill get some photos of my bike at the drags tom n start a new thread of what i changed on it in the past week!
Pro Taper ATV HIGH bend with Houser clamp, I also removed shifter to clean up the clutter on the bars. Relocated the key and indicator panel. All reused factory controls fit on again with this setup with some rerouting. It improved comfort big time from the factory setup.
