Hello i have a 2005 yz 250. im rebuilding my top end. I went to clean out my powervalve and noticed On the actuall sliding valve there is this part on the end it is broke off and laying in the botom of the valve housing. I have noticed some valves with and without this part. Im wondering what its for. I ordered a new valve from yamaha. $268.And on the parts breakdown it shows the valve without the part on the end. i have not yet taken pictures of my pot and powervalve. this part sits just above the holder between the springs on the shafts.

thanks.
