My 78 Xs400-2e needed a new motor. So I pulled apart the spare one and the original one to make a nice new motor for the old girl. I tried looking in some old threads and the manual. Ive had no luck finding the torque specs on the acorn nuts holding the cylinder head to the block. The manual doesn't show the correct size of the nuts, the biggest nut spec they show is 10mm, however the 8 acorn nuts holding my head down are 14mm. Does anyone know the specs, or could give me an idea of a safe torque to apply? Thanks guys.
