I've used a few companies in the past for the black magi/voodoo portion of suspension set up. I was pretty happy with the work enduro engineering does, but was referred to this guy for my 300: http://checkpointoff-road.com/
I have to admit after a couple hundred miles of single track I think it is the best suspension I've ever been on!!! If you are looking for that next step I would highly recommend Matt's work!
Nice. I'll have to give him a shout if my new to me KTM leaves me wanting more.
