Recently bought a 2007 K44 GT and have the hesitation/stalling issue that was remidied back in the day with an updated airbox and software update. So it would be nice if BMW fitted my bike with these parts for free but I understand the age of bike and all and just need this fixed. Issue being no dealership I contact knows anything about it and can't find information on it. I called BMW customer care and while they were nice as pie to me they say they wouldn't have that information I would need to bring it to a dealer. Every dealer says bring it in we'll diagnose the issue for you. Ok so I don't want them doing a million dollars worth of work to it just for the issue to remain because I have the ill working airbox in it. One dealer did look at my history and while the airbox was never updated I did find out they replaced the entire ABS system so there is that, at least I have that already taken care of so hopefully that won't fail anytime soon. Anyone have any suggestions on what I should do?
