[QUOTE="dirt bike dave, post: 1355315, member: 18302"] Yeah, it is very easy to check if the powervalve is operating properly by pulling the inspection plug on the left side of the cylinder. As you rev the motor up, the end of the shaft will rotate 90 degrees as the power valve opens. There is a slot on the end of the shaft, and markings; I think it will line up with H when it opens, and L when it is closed. If the power valve is not opening, there are a couple of things to check. First, open the powervalve inspection cover on the right side of the cylinder and make sure all the little allen head bolts in the powervalve system are tight. However, if the valve is not opening, there is another more likely problem that will require you to remove the cylinder. Basically, when the cylinder is installed on your CR250R, it is easy to misalign one part of the system that operates the powervalve. There is a little 'fork' in the cases that must align with a shaft that comes down from the power valve. If that fork and shaft don't align right when the cylinder is installed, the power valve won't open. [/QUOTE]
