Thanks guys. In spite of following the recommendations things didn't work out for me I managed to crack the clamp on the perch. It's still together but I don't thing I would trust it that way. I am pretty frustrated it took me a long time and wasn't cheap to get the right handlebar controls to do a handlebar master cylinder conversion on my /7. Guess I should have stayed with the stock bars. Going to see if a welder friend of mine with a tig set up can weld the crack or start my search for a new double pull throttle cable with the master cylinder.
