Hello I love my bike with the exception that it starts to "chugg", misfires and idles inconsistently and stops after a start in the hot weather, 90s. I've had it to 2 dealers including the one that i purchased it form, they cannot find a fault ! i have contacted BMW who was to send a traveling tec to check it out at the dealership , the dealer ship never heard a thing from BMW and did not know there was such a thing as a traveling technician. has anyone out there had or have heard of a problem such as this? it is a 2014. O.K. I spelled weather wrong in the heading, I have big fingers!!!
