starting, idle and off idle is the domain of the pilot circuit. so, it's pretty easy to swap pilot jets. hot bikes like a leaner mixture to start. this is what the hot start does..introduces more air to the mixture. so, you could experiment with going down on the pilot jet as well adjusting your fuel screw. just keep good notes on the jet and fuel screw changes and you can also go back to the best set up.
