I have a 2002 Yamaha 800 XLT. Just replaced two the two piston and a cylinder. The power valve that is attached to the cylinder has a bolt that will not lock down tight to the cylinder and I can see it spitting fluid thru it. I assume this is what is causing my engine not to stay cranked and rough idleing. Does anyone know what this loose valve would cause?? Thanks in advance

it is the YPVS cover that has the bolt that will not tighten down. There is four small bolts that secure this cover and one of them is stripped and is causing leaking.
