my bike was sputtering & backfiring, i brought it into the local bmw dealer who diagnosed the problem as "throttle body system" he told me it was "this happens all the time of this year and model bike, even with the low mileage" i had just purchased the bike, if i had know about this common failure i would have not bought it. they want $1800 to repair it. *tr
