    any body know rods ,mains and block halve bolt torque specs or link where I can find this info. Also what is best to seal case halves

    I would invest in a shop manual.

    If its not stamped on the cases, there is a SPECIFIC pattern for tightening the cases back together.

    Yamaha makes a sealer specific for the (gasketless) cases. The part # in the manual is probably different than on-line as some of thise #'s changed(same product thou)..
