I just checked the valve clearance on my 2019 KTM 350 SXF. The valves seem to be in spec, but they are near the limit on one end so I'm curious if I should adjust now, or leave them for a while longer.

Intake limit is 0.10mm -0.15mm, I measured them at 0.11 and 0.13

Exhaust limit is 0.13mm - 0.18mm. I measured them at 0.15 and 0.18.

Since one side of the exhaust is at the limit should I adjust, or continue to run as-is?

fwiw, bike has 55 hours on it.

Leave it. 0.11mm is fine. The exhaust is fine as well.

Valves lengthen as they wear, decreasing clearance. The one at .18 is the least of your worries, it is wearing towards .17, not .19. I would leave things alone until one is below a minimum clearance.

Thanks for the help! I'll let them be for now.

I would've shimmed the .11 one toward .13. But I'm a little obsessed.
