I recenetly got my bike back together the problem is sometimes it starts and sometimes it doesn't. The symptoms are when it does run it idles at 3k rpm for 30secs then 2k for 20 and finally drops down to normal idle it does run rough as well I did check for vaccum leaks and found nothing I then pulled all the plugs and didn't see any problems there either I put everything back on and it started right upand soundedgreat revved it up a few and pushed it back a little bit then I shut it down and rolled back forward and mounted the gas tank. I went to start it again and all it did was rollover but wouldn't start there were a few LOUD back fires but that was it I'm going to change the plugs on wednesday. Does anybody have any advice as to what the problem could be any help would be greatly appreciated. Thanks in advance.
