Valve Qestions 04 CRF 50

Recommended Posts

I think I goofed with my boys bike.. I never adjusted the valves after break in and am now starting to have some problems.. It dies as soon as you let off the gas and I am getting some valve train rattle..

Can anyone tell me the valve specs and is the intake on the top or bottem??

Thanks guys

Valve clearance: 0.03 - 0.07 mm (0.0012 - 0.0028 in)

(That's 1197-2003 specs, I don't think 2004 is different)

Intake on top - Exhaust on bottom

Thanks I sounded like a stupid noob question I never bought a manuel did not think I would have to work on it this soon.. Now my XR 426 is another story.. Anyway is the valve adjustment after break in critical???

On a xr50, not really. Once you get them back in spec, you probably wont have to ever adjust them again, dont you just love the little xr motor 😢.
