Propellor's right, my set up with the fork cap nut as close to the underside of the bars as possible, means I'm still out on the standard setup by 22mm. There's not enough area on the original yolk to mount the risers sufficiently back for the stanchions to clear the bars. Higher risers, or ones with a base cut at an angle should work. Flush fitting fork caps will allen heads will get you up by 7mm, if you can find them. However, as is, I find the handling great and only wanting on fast, downhill sweepers. SteveC has a forkbrace which might help compensate?
Here's an old thread;
