It may be an easy answer maybe not. The intake manifolds have two bolts each. cyl. no.s 2 and 3 outboard are in oil ports all others appear to be dry.
Oem parts show two different bolt part no's and the cave painting from yamaha shows them as two different lengths, longer in the wet holes shorter in the dry.
the oem manual says nothing as far as length in holes it just states torque in criss cross pattern.
long pn. 91314-06016-00 short pn. 91317-06016-00. I don't want to restrict or not restrict oil flow. also no actual bolt length spec.
any ideas?
