Title: 78 YZ 100 bolt torque specs
Post by: Joe on May 29, 2011, 07:15:18 PM

I'm rebuilding a 78 yz 100 and was wondering if anybody knew the torque speces for the following: bolts for crankcase halfs, nuts holding cylinder to crankcase, and the nuts that hold the cylinder head to the cylinder. I would go ask a yamaha dealer but there isn't one near me.  Thanks

Generic torque settings for bike engines.

M10     35Nm
M8       25-27Nm
M6       10-12Nm
M5       8Nm

These are a general rule for bolts into aluminium.
If you cant find any specs for your bike these will get you going.
