Looks like BMW will pick up the tab on installing the cam chain jump guard on the Slant Four K1200 and some of the K1300 bikes.

Technical campaign was released this month It goes on to say this is to be done at the time of valve check and if a customer does it ahead he can be reimbursed for parts and 15 minuets labor.

From what I hear this job can be done in 15 to 20 minutes. If your K1300 was built near the first of the year of 2011 you may already have the jump guard.
Your dealer has the range of VINs that are affected and can tell you if you need the job done.

Parts are the plastic guard, 18 non reusable aluminum bolts and possibly the gasket if needed.

I did not add the years in the title because I do not know the exact years.
