Yesterday I gave the big one a good bath. I hand dried it then went for a ride. After about a mile it began missing, backfiring and felt like it dropped a cylinder. After a couple of miles (no place to pull over) it was back to normal, or so I thought. When I got home it blued the pipe comming off the front cylinder. Any idea as to what happened, or what is wrong. Its an 07 vulcan 2000 classic lt.
