Checking the KIPS

I had my engine completely rebuilt. I set it in the frame and had my finger in the exhaust port and noticed the valve was loose. It's not so loose that it moves very far but loose enough that I can tap on it and it goes up an 1/8 of an inch or so. It this normal?

I also noticed that the bottom of the valve is not flush with the top of the port but I'm not sure it's supposed to be. Anyone know if that's right? Here are a few pics, I took these with my iphone so they may not be very good. I would like to fix this (if it needs to be) before I put my K5 back together.

Peace

I have replaced the side pins that operate the upper valve and this helps but if you still have alot of play then you will have to replace both side barrels thats what it took to fix mine and take the play out of it.CBX

I'm not sure what you mean by side pins? The valves on the right and left sides are solid, I am referring to the center valve.

kaw rider:
sometimes the bushing at the buttom of the cylinder wear too, and top of base gasket surface on crankcase. When Stewart shaved .020 off of my cylinder base it got the slop out of my kips. Or if you are running thicker base gasket.

cbxracer30:
The center part of the the power valve is operated by pins on each side that extend out into the grooves in the side valve barrels . The pins will wear and develope flat spots and or the grooves in the side valves will wear both of these conditions will give you slop-play  in the valve action. CBX
