Check the service manual recommendations.
Have you replaced brake pads yet? I always check fluids about every 10 hours. Check boots, bearings, maybe dielectric grease fittings and spark plugs. You could check and clean clutches.
I'm somewhere around 100 hrs and both lower ball joints needed to be replaced. While I was at it I decided to check the tightness of every bolt I could get a wrench on. Nothing was majorly loose but several needed to be snugged up.
