Hi all. I've got a 2004 CBR600Fi and I've noticed that when I've been out on it and it's up to normal temperature and then I stop for 5 minutes ish to go the shop etc, when I restart the bike it idles fast again, around 2500 to 3000rpm for around 10 seconds and then drops down to normal idle speed. I wouldn't expect it to do that as the engine is still warm. Does anyone know what it could be? There's no other symptoms. Only had the bike a couple of weeks. Thank you.
