Maybe they tested one million engines one mile each.

 

That's kinda what I'm thinking, or they put 10,000 miles on 100 engines but they just kept them on a dyno that only replicated interstate cruising. And they were all 107's.

 

 

I think I read that in another thread

 

...I worked for 23yrs at an oil refinery. Was the same exact thing there. Us field operators would tell these college know-it-alls(green engineers)on what we needed or how something had to work, they'd go back to their office and spend two weeks designing something opposite of what we needed, have the machine shop, weld shop, general maintenance fab it up and it wouldn't work-THEN they would come and ask how it needed to be done when we told them in the first f'kin place how it needed to be done. And people wonder why gas is near and/or above $3 per gallon.

 

I've wondered how far back - in like years - HD designed the M8? Once the bowling ball starts rolling not much can change the results unless early field testing reveals problems. We can assume it was meant to better pass coming emission standards among other reasons.

Then who gets to tell the Big Guy the product needs revising and why or what to do about it? Not some new field testing engineer I bet. Better for some just to cash the check and freshen your resume.

 

 

Somehow in all the years I have ridden Harleys, I have come to learn that Harley & Oil don't agree on their proper containment area !! Inside & Out !

 

Hell we used to watch them have the same issue on the miles in the 70s , It's not a oil pump issue or a M8 issue . It's a case design issue and Indian has the same issue.That's why Indian had a pure
race motor built. On the drag racing side Vance & Hines found every flaw and shared it with HD. You want HP call a drag racing engine builder they squeeze every once out. Indian put Harley in a cubic inch war and they never wanted to go down that path. Remember in racing you tear that motor down every Monday so Longevity isn't a concern.

 

I agree!
