Is this the correct route for the oil pump hose, once it enters the cavity? It's not obvious in my photo, but it's really easy to pinch the hose in such a tight space.

Thanks.

 

Al, I had the same exact thought recently and somewhere in Yamaha docs I saw a picture of it exactly as you have routed.  I think under the engine source tubing, maybe slightly lower.   I have tested mine and it puts out qty as expected.  going to find the resource I mentioned...IF I can find it.

edit:  Page 24 Service Manual has a picture.

Thanks very much.

Is it possible to move the brass elbow the pipe is attached to, to a better angle?

Maybe, but, knowing my hamfistedness, I'd probably damage something! 

The inlet nozzle is a press fit into the pump . It may twist to a better angle relatively easily .
Looking at your picture , you'll only be able to make a slight adjustment , but that's probably all you need .
I've done it on my RD 400 pump , and it moved easily , but on another pump I tried , it wouldn't budge .

A good kink in the hose does save on oil. 

Can't tell from pic too well but make sure there isn't a "high loop" in the bend that will trap air bubbles.  Should be a nice downhill sweep.
