The Repair Manual for R26/R27 says the torque limit for cylinder head bolts is 25 ft-lbs. Maybe R25/2 is the same.

That's correct Allen,

According to the r25-r25/2 workshop repair manual, the cylinder head torque settings are 3 to 3.5 mkg (1mkg = 7.22 ft.lb) in diagonal order.

I'd like to know all the other torque settings, flywheel etc etc. The book only mentions the cylinder head. Does anyone know where I can find the rest, or are they also the same as the r26-27?

I have a BMW Motorrad r25,25/2, r25/3 instandsetzungs-anleitung repair manual which states in german on page 29 gruppemotor:

Montage der zylinderkopfe
... Mit drehmomentschlussel 4,2 mkg uberkreuz anziehen - which I believe translates to something like with torque wrench 4.2mkg tighten up across

hope this helps
