    Torque spec for engine bolt on 1100S

    1999 R1100S. There are 2 bolts at the base of the right hand cylinder securing it to the engine case. Can someone please supply me with the torque spec for these bolts?

    As always, thanks in advance!

    There's two sizes of bolts down there...

    Here's what my good buddy "Manuel" says

    Installing cylinders
    ?Apply 3-Bond 1209to the cylinder base sealing
    face, which must be clean and free from grease.
    ?Oil the cylinder wall.
    ?Using piston ring clamp strap,
    BMW No. 11 2 900/11 2 905, compress the pis
    ton rings.
    ?Install the cylinder and at the same time pass the
    timing chain and the tensioning and guide rail
    through the timing case cavity.
    ?Tighten cylinder down firmly.
    ?Fit new seal to pivot pin for chain guide rail (1).
    ?Install chain sprocket.

    Tightening torque/tightening sequence:
    1. M 8 screw ................................................ 20 Nm
    2. M 6 screw .................................................. 9 Nm
    3. Pivot screw for chain guide rail.................... 18 Nm

    My right side cylinder head gasket leaked a bit when I bought the bike with 6,425 miles on it. Re-torqued the heads when I got it home from Raleigh. Sprayed WD40 and scrubbed the grunge with a toothbrush to see if that fixed it. Nope. Still leaks a bit. No apparent loss of compression, just weeps a bit so I just ignore it.

    Some would say "they all do that" but the left side doesn't.
