Just wondering how many people have actually experianced crank failure in their cvo? Is this a real issue or just a personal preference? If adding more power how much would you have to add for this to be an issue? Thanks

Twisted cranks are not near as common as failed rod bearings. I have two CVO's in the shop now with bad bearings in the rods. Typically Cranks shift when they are abused, burn outs and wheelies ......

My Dealer sees more front rod bearings go out than just about anything else...

Had a bad rod bearing and when repairing had crank welded. Have since heard that the other side can then cause a problem but I haven't had a problem. I don't(didn't) ride hard just happened on a trip thru the mountains.

Burn outs, while very aggressive-looking, won't cause a wheel set to slip, but attempting to bring the f/wheel up will, at least from what we've seen.

I'll bet Steve at Fullsac has a welded crank!

burnouts,probley not,hole shots,defanatly yes.just welding the crank really wont keep it from moving,here we machine 1/2 thru the crank,1/2 thru the F/W and press in .250 pins,then weld over that,pretty rock solid.(and rod bearings are a bigger prob)

No doubt on the hole-shots.
A 3rd or 4th gear burnout, starting on a damp/wet surface will break the tire loose quite easily, w/o a lot of shock to the driveline, if the bike has any real power whatsoever.
The bike will just "float" between your legs.
How do I know this...........

Looks like I better look into welding,as my old Heritage did miles of hole shots in it's lifetime!

Is there anything to keep the rod bearings from going out?
Do the Carillo rods make much of a difference as far as longevity in a touring motor??

A Carillo rod is certainly a top quality product.

So what is failing in the rod bearings?  Bad crank pins?  Poor fit?  Poorly designed oiling system pumping tappet roller trash through the engine?

All of the above would be my guess, along with the "low cost versus quality" part sourcing factor common to many issues at H-D.

Here are a couple picture of what the rods look like that have failed...

And the really ugly inner / front rod....
