Maybe he's got his act together again but for awhile his whole business went to pot. Some of the horror stories I've read over on the orange site are just unreal, amusing or sad. Anything from totally screwed up stuff, missing parts, wrong parts returned to the customer or not at all, never returned phone calls etc. etc.etc. You get the idea. I think his whole business went under finally. Last I read he was working along with or for US Chrome. I guess his work is really good when he's on his game so you decide.
RB Designs or try this guy

Outstanding reputation on KTM Talk, super easy to deal with and totally reasonable prices. Give him a call and talk about your wants and needs for the motor and I'm sure he can do it. I have not read 1 poor review of his work yet.
