Ordered new sprockets. 16 front/41 rear for the F800. Looks like whoever had this before dropped the output shaft sprocket to 15 (16 is what BMW ships them with). Hopefully that will bring my revs down a bit and won't be so buzzy on the highway. My mpgs drop into the 40s when hitting 70mph which tells me she's spinning too much. 1st and 2nd gears feel like they could be towing gears at this point.
