SOURCE: 04 crf 250r.... the head has a chattering noise when running

Any chance the valve spring has collapsed? Cam shaft thrust washers missing? Cam shaft bearing gone bad?

Other than the valve will be slightly noisier, no harm will be done.

SOURCE: I'm checking valve clearances on a 2001 st4 and

Yes, you have 4 valves per side, 2 are intake, 2 exhaust. On the intake, the opener is .002-.007, and the closer .006-.010 , The exhaust, opener is, .002-.009 and the closer is ,.004- .008. If you are planning on doing this yourself, you need to do your math and get the right shims, Ducati will sell you the shims you need, but there are other people out there making them. When measuring the clearance, you need to turn the engine over by hand, pull the plugs, pull the cover off the left side to get to the crank bolt, get a friend to crank the engine over while you runs shims in and out of the rockers, keep notes on your measurements.

MOVE EACH CYLINDER TO TOP DEAD CENTER OF COMPRESSION STROKE ( sorry caps on .) check that timing mark in timing cover hole is in line .remove adj cover per cylinder in alignment and adj valves according to mfg specs. to adj : under adj cover , loosen lock nut on top then loosen adj nut on btm @ top of valves . insert feeler gauge under rocker and adj ,this is tricky to say the least. usually takes several tries to get it right, keep trying the valves must be set right or major expenses can be expected to occur. intake and exhaust settings are different normally at least .005 .be sure to tighten locknut on top before checking if clearance is correct. holding the btm nut while turning the locking nut is the tricky part 4 me anyway. 2 valves per cyl. on most atv eng. adj all valves .start eng and listen to eng w/o reving up. any ticking noise and you get to start over. should be smooth idling and quiet. no popping or backfiring. smooth starting and off w/o run on. should not be performed unless you are familiar with the procedure. contact me or service center near you if not sure on procedure.correct adj. is slightly snug fit . valves making no noise when done .
