Triumph Mountain Cub

Hello,

Fortunately, I noticed my Mountain Cub (1965?) trials conversion bike stopped pumping oil before it got too hot.  I assumed it had a bad oil pump.  I found a new NOS pump for $50, so I went ahead and bought it and installed it (not a fun job).  Unfortunately, my bike still isn't pumping oil.  Although I'm not a triumph cub engine expert, I have rebuilt, from the crank up, three motors and they have ran great after my rebuild, so I do know my way around the motor.  I was very careful to install the pump correctly and it was spotless when I installed it.  Could the "dry" sump not have enough oil in it?  If so, how would I add some oil?  To note, I haven't pulled the copper lines that go to the rockers yet and checked for blockage. Note - the bike had been sitting for about six months prior to me noticing it wasn't pumping oil.  Thanks for any input.
