I've been doing my own oil and filter change, spark plug change, and other maintenance myself for the past 3 seasons. However, I've never done the "impeller duct check and lubricate" or "lubricate throttle valves." Are you guys doing this annually? What are you using to lubricate the throttle valves? The service manual says to use a "rust inhibitor." Would the yamalube silicone spray or CRC 656 be okay for the throttle valves?

where did you get the items from? owners manual or svc manual?

Impeller duct check and lubricate- not sure what this is speaking to, is that simply looking up from the bottom into the "intake tunnel", not sure what there is to lubricate unless they mean removing the rear cap and lubricating the impeller bearings?

lubricate throttle valves - I wonder if they are talking about the inside of the valve, if you sprayed fogging oil in the breather or if they mean the linkage that works the valve on the outside ? I've never lubricated the outside linkage,

I'm planning to empty a can of seafoam intake cleaner probably weekend after next... I'll let you know how it goes.
