Ya ever notice...
On a fresh rebuild of the motor how hard it is to keep from busting loose in that first 500 miles. I just made major changes to the '96 FXSTSB and every time I take it out I just wanna see exactly what the new top end can do!
Oh well, 250 miles down, 250 to go... then the fun really begins LOL

Patience is a virtue! But yes it is hard, although the 'rules' seem strange. My last new bike was my Firebolt and I was given strict instructions to keep it below a given rev limit for a short distance, then a slightly higher one for the next phase of running in. That corresponded to 90mph in top gear, so 'running in' is something I really haven't got done, after 4 years ownership!

Dyno tuning a new EFI engine during initial breakin, big builds with EFI have to be dyno tuned to assure of proper afr's, I know they still heat cycle them on the dyno but then I believe they turn them loose to set wide open throttle afr's.
Attached a completly opposite breakin article http://www.mototuneusa.com/break_in_secrets.htm
We are instructed on a big rig diesels to assure of oil pressure, no leaks and load the engine as soon as possible to build heat in the cylinders, chrome moly rings need heat and pressure to seal, this came from Cummins and Cat engine instructers. Different creatures but have aluminum pistons and chrome moly top rings, Is this best for a Harley, hell I don't know.
