Make sure the oring that sits inside of the top of the top hat is in good repair and isn't blowing out of its place. Pm5's have a tendency to blow that oring out of place with too high of pressure.
Also be sure you are using Dye slick lube or (my preference) slick honey (found at cycle shops if you don't know
) This will ensure the bolt doesnt need too much pressure to move around.
Honesty and Integrity are the basis of a true man. You cannot have one and expect the other. Both must be earned and fought for. It is not easy, nor should it be. I will not be tempted into making the easy decisions over the right ones
