I built a predator 212 motor with a .40 rod ,hemi flat top piston, billet lifters, 1/4 in cm pushrods ,black mamba cam, arc flywheel, champion rockers and a 24 mm mikuni carb. I have the motor in a mini bike and have ridden it about five times when it stopped running. I took off the valve cover and saw that the champion rockers were broken. This is my second set of champion rockers because the first ones broke from crooked studs. Can I get away with using the stock rockers and push rods? I'm using 26 lb springs and don't know why my champion rockers broke I thought they were supposed to not break?
