From a recent MCN article:
"Many early examples of Yamaha's stacked transmissions had inferior shift quality, because the normal splash lubrication scheme was inadequate to properly lube the upper components. A dedicated oil line for the upper shafts was the answer, something that's promised as a fix for the 2008 FJR we are told. If it works, we'll have one less quibble with the FJR.

From the service manual it appears that the FJR has oil piped to these transmission shafts. But maybe they're increasing the flow rate. Who knows?
