Since taking my 06 900 classic out of winter storage I've been having an issue starting the bike. I had it apart to do a valve adjustment, fi2000 power pro, opened up in intake a little, and a new lithium ion battery, all new fluids. When I try to start the bike it turns over and fires up for a second and then dies every time unless I blip the throttle. Once I blip the throttle it runs fine and idles at the correct rpm. I have the service manual and I can't seem to find anything relating to this. Is there a cold idle adjustment that is different from the main idle screw/cable adjustment to the right of the intake? Any ideas?
