Here is a four part series of videos on Harley crank shaft run out,

particulary as it pertains to the twin cam 96 that should help to parlay all of the fear and hype being thrown around about inferior crank shafts in these engines. This is someone that makes sense and is not talking from a "I've been screwed by Harley perspective"

If you are somewhat mechanically inclined its pretty easy to understand what he's saying. He chooses his words carefully as to not offend anybody, either his peers, the average mechanic or Mother Harley. He has a smooth way of drawing a logical conclusion on the crank run out issue. See what you think.

I think its funny how the crank fell apart on the desk and took a chuck outa it

the fact of the matter is that harley knows there's an issue thats why the have an exceptable tolerance of .012" and that if you have more than .003" runout don,t even bother with gear drive cams

I have seen a few now from .0015" to .007" and only two below .003"

also here of a lot of guys getting the Dealers doing cam changes and not even measuring the crankrout because they maybe to scared to tell the person that owns the bike what it is

Lucky my 120r has only .0015" runout and next time I am in the Cam chest I can check it again to see if gets worse

0.012" is just ridiculous. anything over 0.001" or 0.002" is bullshit for motor parts.
Yes I'm fitter machinist and work to those tollerances daily.
I'll be very interested to see what mine is when I pull it down in a month or two for cams and 106 kit
