HI, I'm new to this forum, but not motorcycles i recently bought this 2007 ninja 650R fuel injected and it runs great once warmed up, but cold start is not working pulled gas tank and breather box, you can see the choke plates close when keys turned on but open completely back up a second later. causing a cold start issue any help on what i can do or check will be greatly appreciated. PS, the bike only has 2,670 miles on it.
