So after I finally rebuilt my 750, and finally started to learn riding, I'm having issues with the warm starts. When I first started it cold, started fine, only needed slight choke, and idled ok. Cut ahead, I shut it off, and it cranked, but took a long while to start. Finally, when it did, the idle RPM was stuck at 3-4000 and wouldn't drop, even when revving. So I adjusted the idle control knob, got the RPM down to 1100, and now when it shuts off, it needs more of the choke lever out, and still starts hard (though easier), and needs some throttle when cranking. The idle was 1500 this time, so I adjusted it again to 1100. So what can be the cause of these hard starts when warmed up?
