Arrow Rebuild Break - IN Question. Opinions Please.

[coiled]

just got engine back from arrow and have the break in procedure sheet.

2500 rpm max first 200 miles
Oil Change
3500 rpm max next 200
4500 rpm max next 200
5500 rpm max next 200

I talked to arrow, they said that the engine had mostly been broken in on the dyno for 2 hours and that TSB on engine break in was very conservative.

Is it better to follow these guidelines to the letter or break it in hard, so it drives hard???

thanks

Rev it up Drop the Clutch, Do the biggest baddest burn out you ever did...If it doesn't break....Probability is it won't....If it does it would have anyhow

In reality I would break it in fairly easy. New motors or rebuilt are very tight in comparison to engines of old. I would maybe be a little less stringent with a rebuild, but I definitely would not play "Hammer Time. " Change the oil at 200-400, but follow the guidelines( somewhat ), as they wouldn't send them to you if there wasn't a reason.

I agree with Bill. I've heard more than a few reasons why a conservative break in is a good idea.
If anyone has any science to back up the idea that no break in or hard fast break in, makes sense, let's hear it.
