Sounds lean on the bottom...


And you don't have to let the bike warm up for 5min. Maybe a 1min at most...

Replace the pilot jet.

Bike should always need the 'choke' on cold starts.

Umm... A 2010 doesn't have a "choke" or a pilot jet.
Are you sure your idle speed is correct (1950-2100rpm)? It's adjusted by turning your "choke" (cold start).

Reset your idle and go from there sounds way too low

Pull the knob out let it run for 1 to 2 mins and push the knob in. Set idle to 2100 to 2200 rpm and ride it. most of the time when the bike is ridden hard or as the engine gets hotter the idle will drop even further down around 1800 to 1900 which may flame out down low so try to shoot for 2000-2100

Idle should be high enough to start off without touching the trottle, these bikes don't like a low idle
