So my friend has a dyna 1340 evo and one of the lifter bearings had seized, but luckily there was no damage to the piston or bore so the front head has been refitted i followed the settings on a video on my previous post about torque settings with new gaskets.

However before the bike is turned over with new oil in it, does anyone know how i can check the oil pump is working/feeding oil sufficiently other than checking oil pressure ? as don't want the hassle of another bearing going and lack of oil again which is what we think it is or could it just be the bearing went anyway ?

Many thanks John !!!
