[Shotimes] rod bearings

[John Weidenbenner]

That's interesting. I've only examined one 3.2 engine rod bearings during a
conversion at 45k miles, but they were in good shape by Plastigage checking.
The larger pump must be to compensate for the increase in reciprocating mass
since the atx can't be lugged. Too bad that Yamaha didn't retrofit the
larger pump design for the 3.0 and make the 3.2 pump better.
