    Total Twin Cam 3,380,123 Engines, not sporty, no Vrod just big twin.

    So tell me again with 3.4 million engines on the road, how many have you seen having inner cam bearing problems?

    Lets say someone could record over the time 15,000 bad inner bearings thats .004438%

    Lets say it was 150,000 bad inner cam bearings.. thats .044377 or still less than one half of one percent of production.

    I'd say you'd be nuts to do that work...

    CB lets get one thing straight here: IF the inner cam bearing shows sign of failure with 31,000 miles on it, HD did put junk in it. If the lifters are showing scour marks, than HD put junk in the engine. If the cam lobes show wear at 31,000 than HD put junk in the engine.

    The factory inner cam bearing has spaces in-between them.

    you can't see wear in inner cam bearings dude. Hello.
    HD don't even recognize this as a problem. Its not even on their maintenance list.

    A retired Mechanical engineer has seen the problem and thinks it needs to be a maintenance problem added to your maintenance list.

    HD has gone to inferior parts . Look at their crank that is pressed together.

    That's why people replace the inner cam bearing with Koyo, which is who bought torrington out.
    And there has been severel lifter failures.
    HD has gone to larger tolerances on their crankshafts .
    That is why we have had a lot of the problems.

    Here is a picture of the Inner cam bearing you have now vera the Koyo

    Ask Darkhorse crank and other machinist that does Harleys cranks why they are doing so much work.
    HD tolerances are too loose.
    They could build a better crank if they wanted to spend the money.
    And they could use better bearing and all if they wasn't trying to make so much money for their Stockholders.

    The people at HD are genisus at marketing and knowing you are going to do upgrades.

    Google Harley cam bearing problems. See what you come up with.

    More innernet bullshite....

    The bearings HD puts in are specified to handle the loads generated
    by normal operation of a stock engine.

    We have dillweeds puttng mild cams or even building bigger
    engines and not replacing the inner cam bearings.

    You also have issues with installs, if the machine on the line gets out
    of calibration or the installer had too much grog and sausage at the WI
    nightly beer pub crawl...

    As to the cranks, HD doesn't built high performance engines
    they build stock engines designed to last and provide performance, economy and
    meet EPA standards.

    They don't need to build perfectly balanced cranks on the odd chance that some guy will decide to hot rod it.... It's not the idea, it's mass production.

    3.4 million, again how many stock HD twin cams can you
    list with problems, its nothing.

    Now if you are changing cams, change the bearings...
    Other than that unless you have high miles and want to
    freshen it up, leave them alone...

    Sent FLHT a dude that had a Stock SE Ultra.

    Bike was Stock. Lifter went out. trashed his motor.
    It also showed he has the oLd style inner cam bearing with the space between the bearings
    Have you been doing much with the newer motors in the last 4-5 yrs ?

    It's all bull CB like HRK said millions of em still out and running normal. Besides the SE 110 is build better that the 96 like you have. That guy probably didn't change his oil properly
