My girlfriends 2002 750 has a hard time starting when hot. If you shut it off and go to start it within 20 min it needs choke to start. I have not started on the mods to the mixture, carb sync, relay for the coils or vent hose yet, but I will soon. I ask because I have not yet seen this problem described on the board, and want to be heading in the right direction when I start. Will removing and cleaning -adjusting the carbs likely be the fix?
