Curios to what your thoughts are to break in procedure??
If everything is new, I kinda believe in the long easy altering loading menatality.
What do you guys think on that and also what if its just new bores/rings??
I personally think thats the most critical to "wear in" properlely??

I go along with your thoughts on break-in. I go to 40to1 instead of my usual 50to1, run a couple of hours on the hose because it's convenient, and then take it easy for a total of 8 to 10 hours.
