Quote: Well, as far as the fuel chain goes this winter I switched out the stock intake manifolds and rubbers for the billet aluminums from newspeedy.com
I've made a lot of mistakes during my life and my motto is "always go back to the last thing you did" when I hit a snag. Is it possible that you are developing a vacuum leak at the new manifold? I ask because it seems your bike has to "warm up" to fail and since I can't see it I can only speculate on a gasket/joint failure when warm. Try shooting some WD-40 or carb cleaner around the edges and see if any gets sucked in...
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
