Picked this smoker up last year and after rebuilding it, I put 13 hrs on it this past summer. Winter is here so looking to do a fresh top end. Does this look normal or do I have bigger issues? Thanks.

Also, leaning out the air screw only works in your slow circuit (idle and just above idle at low throttle openings.)
For most riding scenarios, your needle position is what controls the jetting, in combination with the main jet size. I would start by leaning out your needle by a click and see if that gets cleaner. (Move the clip up the needle one position so the needle projects out of the throttle slide farther.)
A impact screw driver (not a powered on but one you hit with a hammer) will help loosen the screws.

That said, if you’re just doing main bearings and seals, you don’t actually need to remove either of those parts (powevalve actuator arm and selector paw). Here’s a picture of an RM125 engine I split, where I left the powervalve assembly in place.

Looks like a roller bearing cage. Inspect carefully!!!!
