Started my annual service and found the cam timing a wee bit off that I corrected with the help of some BMW specified tools.
Cam alignment and chain tension tools.
Tool for finding TDC.
Cam chain tool in position.
Left side cams at TDC.
Cam alignment tool in place - cams slightly out of alignment.
Cam trigger sensor removed.
Crows foot to loosen the cam gear retaining nuts.
Adjusted and aligned.
Tighten cam gear nuts and install cam sensor trigger and align.
Remove chain tension tool and install cam tensioner with new washer.
Check the valves (all in spec), button up the bike and move to the next task.
