Proper piston circlip installation

[MM70001]

Does Yamaha shops use a circlip installation tool like skidoo? Or is there another technique suggested?
Also is there any sealing agent used on head or base gaskets or are they assembled dry?

Is this a new install with new gaskets? New gaskets are left dry, used gaskets i used some copper spray. Not sure on the circlip never been that far in yet!

if you've ever pulled a piston you've done a circlip. I usually do them with my fingers. not a lot to them. I'm sure there's a tool but for a piece of 1/16 wire.......

No piston just pulled a jug to get a busted exhaust bolt out. The guys told me new gaskets dry and seeing i left the base gasket as is to just use cooper spray. Never had to do a rebuild yet. But will this next off season. My vipers getting up there in miles.
