Anyone know of an problems with the new rear cylinder drop on the 2009 Road King? I have been playing on my new one and going up a hill it seems as if the motor is missing and has no power. One the way back with four of these friday we thought it might have been bad gas, but they were all fulled at the same place and only three of them did this. Two of the bikes were set so that the rear cylinder will drop as it was explained to me only if the engine runs hot. Not sure it the other two were set on this setting or not. It only happens going up a hill. Any thoughts?
