I hate to be the guy with one post who asks a question or for help but I have to do it. I have been reading this forum almost everyday for close to year but just never created an account. I'm in a bind and need some advice. Sorry if the post is long. At the end of January I bought a new 2012 Vulcan Voyager. I love the bike but have been having some issuses that nobody can figure out. Basically when the bike is hot it will not restart or starts with a sporadiac idle and stalls. I was convinced it was an intake leak but no longer believe so. The dealer has replaced the throttle body with no change. The kawi rep disassembled the TB and used new seals and gasket sealer (plus intakes also) with no change. They have messed with California emissions with no luck. There are no stored codes. The bike will consistenly run well into the red zone and past with one instance of bubbling in coolant resivior. All of this appears tied to the heat (hotter out/longer run worse starting condition). I live in Vegas and will ride when it is 100 plus degress out. I have been dealing with the Kawi rep during the last 3 repair attempts. He is completly stumped. I love the bike but am losing faith in it. Is this a common problem? Did I get a Monday morning bike? The bike is all stock with about 4500 miles. Has done it since 400 miles (first warm day). Help!
