After careful measurement of the lift of my CB125T camshaft , it appears to be a reduced effect cam with a lift of 5.5mm .
I have been looking at various posts dating from 2012, where it suggested that a RE cam could be reprofiled to achieve full power FP lift of 6mm
Who could do this work?
I have tried Joy Cams, but my email was returned. Is Phil Joy still trading?
Any recommendations appreciated.

I had a standard Honda CB750F2 bump stick reprofiled for fast street/track and Newman Camshafts in Kent ground off 0.75mm off the base circle of the inlet and 0.5mm off the exhaust lobes.But to help get the full benefit I had to change not only the inlet but also the exhaust.That and the ports were smoothed,the valve seats were ground to different angles and the valve springs were upgraded to S&W from the USA.
