Valve Adjustment CB250RS

[Petter B]

Hello,
I am Petter B from Holland. I have a Valve adjustment problem on my CB250RS. I cannot adjust the outlet Valves. I manage to make the adjustment on te he first outlet Valve, but when I set the Gap for the second outlet Valve, the Gap of the first Valve is gone under spring pressure of the Rocker, this sets the gap back to zero of the first Valve and Vice Versa. In 2013 was a Topic with the same Problem

I do not understand that solution. In a new topic I hope op some help, a kind of step by step explanation. Thanks.

The solution is (Thanks to Neil):
Pull the rocker up away from the valve stems until it stops against the cams
Screw the adjuster screws in so that they almost touch the valve stem (with rocker still touching the cams)
Slip a feeler gauge between the valve stem and the adjuster screw until you can just feel resistance between the feeler and valve stem.
Once the gap is set between the valve stem and adjuster screw you can release the rocker. The rocker will now spring back and the valve stem and adjuster screw will now touch.
The gap you set is still there, but it has moved to be the gap between the rocker and the cam. This is correct for setting the clearance.


Neil is Great! Got it, all runs well now, End of Topic
