fuel pumps not developing proper pressure and thuss the injectors don't work right
if you can put a pressure gauge on the injector line to see what the pressure is
not sure what is within specs but CSC would be able to tell you

Bob, I have a new ECU (GoBoom tune) installed. Issue pre-dated the ecu replacement. I just changed the MAP sensor and checked the spark which seems strong. I'm still leaning towards a fueling issue. The bike runs and pulls without a hiccup once started. I've still been commuting to work on the bike. It takes 3 trs on the starter to get running. Priming the ignition multiple times makes no difference. I have no ability to check compression with the bike having a camshaft driven compression release and obscure 8mm spark plug thread.
