I'm a Non-Destructive Testing Technician. I have those indications on mine too. They are a Bi-Product of the Casting Process at the Manufacturing Stage of the

Hub. Don't worry about it. If they where Actual Cracks, This whole web site would have been doing nothing but talking about this for years now! All is Good!! :D

I'm a metallurgist who specialises in aluminium (note the correct spelling) processing and I agree with the above. These raised areas are evidence of thermal fatigue cracks that were present in the pressure die casting mould. The aluminium gets forced into the crack while molten. Unless they get really big they are just left alone. Eventually the mould will be repaired/replaced. They wont casue a problem with the function of the hub. Mine has them too.

I'm a psychic, and I'm gettin nothing from the convergence. We're good.

 
You may or may not have had an '05 or earlier, but those of us that did saw first hand how Yamaha's quality control failed and how they never formally "fessed up." It was the "question-answer-discovery" process that began predominantly on Boards like this that armed many people with the information necessary to get Yamaha to right a wrong.
Huh? WTF? What the heck are you talking about?

I have seen a few posts about the paint cracking and Yamaha replacing the unit. That hub gets pretty hot but so does the motor. I remember seeing the posts listing multiple years that this has been an issue.
Well, I sure would like to see them. I am pretty much a regular around here and I have no idea what your talking about either. I suppose it's possible I missed them but I really doubt it. Please, provide links to these threads of which you speak.

 
Blah, blah, blah

mutter, mutter, mutter

Well, I see the ball buster has arrived on the scene. :lol: (ducking and running for cover)

Thinly veiled reference to Gen I tickers, I'd say.

Beats hell outta me, and I've been around a coupla weeks, too.

Yeah, that's what I figure too. I just wanted to verify before I pounce. ;)

 
Yeah yeah. Very funny. Wish I'd never bothered now. :p
No, jeremyr62,

I just wanted to sprinkle a little water on this hysteria that was starting to rage here. Your post was spot on but with a bit more detail than mine.

I'm not a metallurgist but in Non-Destructive Inspection, We get all the training in material processes we need to separate what's a real crack and what's

irrelevant and ignorable. :good:

Well now it's pretty much confirmed.....we're waiting. :ph34r: :assassin: :ph34r:

Reading my post I did sound condescending and pompous so I reckon I deserved it. It's my cross to bear... :)

 
I too am in the non-destructive testing business and agree with majicmaker. I haven't looked at my bike yet and the pics supplied are not too informative but I suspect it could be a casting flash that wasn't cleaned up totally and caught some dirt. If the there is a raised edge you can feel I would expect a more gaping crack. I'll check mine and if I see anything suspicious I'll do a little surface eddy current testing to try to identify it.

Glad to meet you TILAM,

High Frequency Eddy-Current won't help. (I tried it). All you'll get is the signal of the probe lifting off while climbing over the ridge.

But, give your machine a try. Let me know what you find. :moil:

You lost me after "Glad to meet you."
I know. But, don't worry. Not too many other people get it either. That's why it's a great line of work to be in. :yahoo:

*************************************************

If you are counting on HFEC (High Freq Eddy Current, not to be confused with Low Freq Tidal Current) to tell you anything, you are surely going to be dissapointed. Everyone here knows that by reversing the polarity on the Flux Capacitor and then measuring across the clitorical chasm, you'll verify the veracity of the erectile dysfunctional ridge. <_<

 
Damn!! Didn't know we had a few NDI Techs on this board!! AWSOME!! Now, forget about the damn hubs and LET'S SHUT UP AND RIDE!! :clapping:

 
Sorry I haven't had a chance to try the HFEC on mine yet. Too busy doing HFEC. In fact I haven't even checked it visually.

I'm going on a 2 week vacation (with the FJR) on Saturday and am not worried about it if I don't get to if first.

Maybe tomorrow.
