I believe he uses a maico decompression unit. He drills a .050 hole or so between water jacket into one of the ports I believe after Milling a flat surface.. The ama racers in the 500 class all had compression releases and yes I am sure there where some who could not start their bikes without it.  Who would not want to save there energy for racing and riding? So you can run a little magura lever he sends you or you could run a works connection style with hot start lever...which in my opinion would be great...
