1998 Elite SA50P Valve Adjustment

Hi everyone,
I don't think I'm just missing it, but there's no information on the valve clearance specs in the service manual I can find? How often should the valves on these things be checked/adjusted, and what are the clearance numbers?
Thanks!

The owners manual will have info on service intervals. The service manual will run you thru it. By valves I’m assuming you mean replacing reed valves since were talking about a 2 stroke motor.

You seem to be missing the BIG picture FredB32.
Your scooter has a 2-stroke engine, which, by design, does not have "valves" as you find in 4-stroke engines.
Keep calm, and carry on....motor

Duh...thanks guys. 2-strokes are not necessarily my specialty. I got bogged down watching a bunch of valve adjustment videos for mopeds on YouTube the last couple days and got to wondering lol...I actually do know better, but my brain has been a bit of a mess lately.
I guess while we're at it, since I have the cover mostly apart and checked the compression last night, is there anything else to look at or check/clean up while I'm there? Looks like just the 4 bolts to remove the...port cover, I guess?

If the square, finned item with a spark plug in it is what you are calling "port cover",
NO...that is the cylinder head. You could remove it and de-carbon the top of the piston and the inner surface of the head,
but you really should replace the head gasket if you do that.

Thanks Mike - that's essentially what I was referring to. Seeing as how this is a 1998 model it might not be the worst thing to do, but since the compression is good I'm also thinking it might not be worth the effort. Tested out at 130 psi yesterday, so internally things should be good.
