Hi, I'm having some problems with my bike starting. It is almost impossible to start without using some ether, however after it's warm it's much easier to start. Also once it's running it will run all day and run great. I'm at wits end, I've cleaned the carbs checked to be sure it's getting fuel.. It is. I've tried starting it with the petcock on "prime" it doesn't help. There is a spark to all four cylinders. I have noticed though that when it's running the middle two cylinders (2&3) the headers get a lot hotter than the outside two. I don't know it that matters but thought I'd throw it out there. I just bought this bike to ride to class but it's so unreliable about starting that I can't even ride it there. Any help would be greatly appreciated!
