Thanks again D, you are wise in the ways of the rockers I think you're right.. the wiggle (side play) allowed by the clearance .05mm - .010mm is normal... this makes sense. The adjuster tip not being aligned properly with valve stem center.. not normal... this also makes very good sense so...

Yamaha service manual states " note: lubricate bearings immediately after inspection to prevent rust formation" no suggestions as to what with of course.. Does say to generously apply oil to rockers, cam lobes, valve springs and all prior to reassembly. 5twins is most likely right on this one...

I've got a good question for the pros about rocker arm shafts: how much play side to side is normal? should it have any wiggle at all?.. during my last tune-up i recognized that there is greater lateral movement at both exhaust rocker shafts than on intake side. I haven't torn it down...

Tron, I'm in east sooke about 35 minutes away from Victoria... You must be around here somewhere too I take it?
