Ever think about waiting to change that break-in-oil, change it know!!!!! this is after a 5 minute break in on a new crf230f. Those are some big chucks.
...The excess hardened sealant eventually breaks off and finds the oil screen, a process which often continues long after initial break-in, and on occasion to such a degree that it clogs the screen sufficiently to cause catastrophic failure.
As the man from N.M. stated, oil is cheap.
