I'm interested in knowing if any of you out there have put 100,000 mile or more on any Harley engine without doing any major upgrades to it, and if so, whats your secret?

Harley Davidson's Evolution style motor was to be their first 100,000 mile motor when the owner keeps up regular scheduled maintenance and riding like an adult and not a whacked out adrenaline junkie (those types need sport bikes). Porche mapped the Evolution motors for 100,000 hours and the new Twin Cam was mapped by Porce at twice the hours... so in theory if the bike was ridden regularly and all the maints intervals were followed your motor should be pretty much worry free (in a perfect world). Not really much of a secret, just try to follow the Harley's advice.

Man the group I run with we all have 100,000 plus on our bikes. Pretty much waht everyone else said... take care of it and it will take care of you.

Thanks guys for your input. I still think Harley had a better engine in the EVO due to the fact it had gear drive cams instead of the cam tensioners on the Twinn Cam. To which I had to replace at 29000 miles. My type of riding, is mostly touring, no hotdogging... Gear drive would make the engine more bullet proof. Don't ya think?

Not sure about that Coley, Rex is a Twin Cam with 62,000 now and except for a shorted stator has been trouble free.

I too suffered from a stator fry! But mine was caused by something far more sinsiter than a short! My clutch hub had been deteriorating for sometime that I was at the time unaware of... when I fried out my stator I thought "Man how tyical, middle of Sturgis and it's 99 degrees!" Well upon further diagnosis I discovered that a piece of the clutch hub had made its way through the oil bath and around the rotar right into my stator! That's when I discovered that my 2007 models have a one year only stator, so I have to upgrade that soon!:(
Also, the new twin cams no longer have chain tensioners, they are all hydraulic now! 4 ft/lbs of tq to the chains vs. 45 ft/lbs of tq! YIPPEE!:-)

Am I mistaken or did I read somewhere (AIM I think) that the hydraulic system can be retrofitted to the older twin cams?
