Found this interesting.Break-In

 

I was talking to a buddy of mine about this artical just today. I wanted to get his input being he has a dyno in his shop and he has been dynoing (is that a word?) high performance street bikes for years. He has had several customers that have followed "Moto-man's" break in tips and agrees that it is definitely an effective way of seating the rings BUT he still is not sure how he feels about what the rest of the new motor is "feeling" during this somewhat aggressive break-in technique. Read some of Moto-man's other articals......this guy thinks outside the box (as he puts it) on just about EVERYTHING.

 

I have talked to a couple of MC/ATV mechanics about this article myself. They both agreed
for a racing engine that will be rebuilt every 100 hours this is the way to go. For your and my
quads, no way. Rod bearings, valve guides, cam surfaces would suffer, as well as every other
part that needs a gentle seating in engine and trany. They did however agree with changing
the oil & filter after a few hours. Makes sense to me.

 

Excellent article. Although I never abuse my machine, I ran it hard from the beginning. I will put my 360 up against any other one out there and I feel my performance is as good if not better

 

But, you WILL be overhauling it before someone who does a regular break-in procedure. I quarrantee it.

 

I agree with the article. I'm an aircraft mechanic and that's how an aircraft engine is broken in.

 

Only if you want to. In independant tests at my uncle's engine building shop, the engine was actually in better shape after the end of a season than a normally broken in one.

 

I agree too. I used to take brand new diesel trucks and load them to 80k from their first day and got 600k-1million miles on them before they needed to be rebuilt.
