I have the same problem. I've put Emig underbar steering damper mounts on, along with the Pastrana FMX bars, and it's still not enough. Fastways are the next step, but it still may not be enough. If I raise the bars any more, I'll have to replace all the control cables.
For reference, I'm 6'4", but I don't have particularly long arms--the sleeves on a 46R jacket are long enough.
Problems cannot be solved at the same level of awareness that created them.
