I just purchased a DR 50 for my grandson and need to adjust the valves among our things. I am looking for a service manual for this bike. Any help would be appreciated. Mark

Welcome to the Chinese Dirt Bike Forums on! There are numerous Chinese motor valve adjustment videos on YouTube:

Chinese motorbike adjust valve clearance 1

Valve clearance specs:
  • Intake: 0.002 inch (0.05 mm)
  • Exhaust: 0.003 inch (0.076 mm)
There are many other check and maintenance procedures in the owners manual: changing the oil, check-up of spark plug, valve inspection, checking & cleaning the air filter, adjusting the throttle cable, adjusting the carburetor, adjusting front & rear brakes, chain adjustment, etc.

Hope that helps!
