Are these things really this cold blooded?

So I have had my RC for a few weeks now and it seems very cold blooded for a fuel injected motorcycle. It came with a PC3 but I am not sure if it is mapped well. When I start it, it really likes to have the fast idle/choke engaged untill I get a few blocks of driving. No matter how long I let it idle(well several minutes anyway) is will die if I take it off and rap the throttle or try to drive off.

Is this normal or should I look into getting it re-mapped?

when I fire my bike up ..I will let it run for 20 sec on Fast idle/Choke ..and after that ..I will close the Choke and go in the house for several minutes to put my Jacket and helmet on .. to take off for the first time.,,I have to play with the clutch else it will die.

I would check the throttle body bolts to the intake. Check the air box too to make sure it is sealed well. I had an issue earlier this year and found that the idle screw was out too far not allowing the engine to run at idle without the choke out.

So do any of you leave the choke on for the first few minutes of riding?

no you are not supposed to ride with the choke out. sounds like you have an issue. i literally only use the choke for startup and shut it after about 10 seconds, then let it sit idling for a minute or two. On cold days it sits open for about 15 secs.

Check your idle screw and your pc3 map/connections. sounds like your map might be messed up.

I let the bike idle to 2500 rpm with the choke on and after that I let it idle on its own until it reaches 125 degrees before pulling off.
