I was installing an SLP pipe tonight and noticed one of my power valve cable housings was loose (you can wiggle the tube back and forth). It is the u-shaped tube that goes through the exhaust valve cover. I checked the 2 small bolts holding down the cover where tight, pulled and cleaned the power valves, they seemed fine. I checked my brothers and both of his and my other one do not have any play in them. I didn't have time to measure the cable play and is wasn't running funny when I parked it. Just trying to decide if it could be a problem some time. Thanks.
