Just had my 1977 Honda CB750F rebuilt  from bottom up.  Shop put in during rebuild a 836 kit.  Got bike back and oil pressure at start-up is running 73psi.  After riding the bike for about 30 minutes at 80 degrees Fahrenheit, the oil pressure on my 100 psi analog gage drops to 0. Low oil  pressure light does not come on and no internal noise in engine, though I don’t wait but a second then turn bike off. I have checked the bike with 2 oil filled 100psi analog gages and get the same readings. No help from  shop without more money.
