My 06 America (8,900 miles) will periodically stop firing on right cylinder. Usually happens when its hot outside (90 or above) and I´ve shut engine off for a few minutes. As soon as I start the bike up again only the left cylinder will fire. Sometimes this lasts for a few seconds and sometimes an hour. Anyone else having this problem and if so, what was the cause? I´ve had mine in the shop twice and the dealer can not figure out whats going on.
