Just talked to Kenny Roberts on the phone.  he can make us a pipe for the 85 & 86 250's!  He just needs someone who lives close to Rancho Kukomanga to bring their 85 or 86 to him so he can custom fit it.  I highly recommend others to call him and place an order.  I've been looking for somebody to build a pipe for the early models for a long time.  Nows the time to do it!  I can't wait to get mine installed.  I believe he quoted me around $650 for pipe and silencer.  That's a steal!
