Just curious to know if newer straight out of the box engines sound differently then one thats already broken with a couple hundred miles on it.
 
only difference is less gear noise from the primary gear on the worn in one
 
So I'm thinking the engine is getting more oil the longer it ages. Probably best to keep the gas oil ratio to 16:1 at first.
