when I pulled the bike out this spring it was hard to start and when it got going it idled rough and would not go to fast idle, took it for a good ride and now it starts good when cold but still won't go to fast idle. Any ideas ?

Idle should be set around 1050rpm. Air temp. sensor in your inner airbox might not be sensing the temp. Could check your engine codes to see if it comes up by using ECMSpy or This way (http://bcrider.com/DDFI.html) if you don't have the ECMSpy cable.
