Question Help with noise

Bike is a '98 Ultra Classic and is making what sounds like a heart beat but only on like every 4th revolution. Gets louder the hotter she gets but no banging or tapping. Also seems that when I rode her she seemed to bounce around. I mean the whole bike at about 40 mph. I just replaced the motor mount, compensator and nut. This sound was there after an escort ride and have been told its a connecting rod but not sure. Bile has 81k miles and was running tight and great til this happened, she also started blowing oil out the carb which is new. HELP This is the sound but on a different bike:
