Since my engine was replaced (7 k miles ago) I have not had one more problem. I attribute this to a very rich fuel mixture, new pipes, aire cleaner, and cams. My mpg stinks but my engine does not leak and runs great !!! FOR NOW

All of which addresses what was stated just earlier as the main suspect in all of this:  extreme heat.     spyder

this just sounds like a" COPOUT " to me. 

sorry,  just couldn't help myself

I'm under the impression that they're changing the crank bolt the holds the compenator on, not the center case bolt. The center bot is on of the bolts holding the cases together Jim.

Hoist!

You would be right Hoist, the re-call...oops enhancement part you're referring to is the compenator nut, which was a poor design. Finally a new design for all.

[copout221]

Ditto, for about 14k miles.  Then started slight weeping in the usual place.  Still runs fine and hopefull will until I can get 'the fix.'

 :nervous:I check mine everyday for leaking. I'm sure it will happen eventually unless the MOCO has actually fixed the problems .

I don't think so. The letter to the dealer clearly states crankcase bolt, not crankshaft bolt/nut.

The MOCO heard an unsubstantiated rumor that a few bikes weeped (not leaked) oil at the crankcase bolt....so they wanted to jump right on it and offer an enhanced bolt/nut before they had any unsatisfied customers.

I wonder how they will replace the bolt on the wife's bike? I bought the MOCO chrome cover and the bolt they supplied didn't even fit. I had to purchase my own. Another fine wood shed engineering Ph#$ Up.

The following may be a lot of smoke blowing out of my azz, so take it with a grain of salt.

The reason I wondered about the crankcase bolt was that I've read of a significant number of them "weeping".  My theory is that when the cases are bored for the oversize cylinders, some of the castings have a break-thru that exposes the center bolt to crankcase oil mist.  Since the bolt isn't normally running in oil on a standard bore engine, normal installation doesn't include a gasket or sealer (at least not in my shop manual).  It would seem to me that a simple gasket under the head of the center bolt would solve that problem.

BTW, the attached photo is included only to help visualize my theory.  The photo isn't of a current model engine, but the idea is the same.  The red arrow indicates where the tool broke through into the center bolt cavity.

Jerry, have seen what you're describing on two bikes of acquaintances locally.  On both I just put crush washers like behind a banjo bolt on them.  Brass/O-ring type.  Never had a moment's problem with either after that.  Seemed obvious that oil vapor/mist that shouldn't normally be behind the bolt was there.  Sometimes there really are simple solutions.

Mine didn't weep, it sprayed!

Jerry, I think your theory is spot on. The crankcase bole actually has a relief machined in the shank to provide the necessary clearance for the cylinder spigots indicating a breach of the case material.

I won't be getting the new bolt, unless they give me one in polished SS.

It is a darn good theory - Jerry knows his stuff.

Doubt I will get one in polished SS.  Maybe I could powdercoat it?

Tell you what worried me with this bolt is the liberal coating of Silicone Thread Sealer it's inserted with - chunks of cured silicone floating about amongst the oilways didn't inspire me with confidence....

Does this mean that trying to install larger jugs like the 113" would be out of the question?  You are a smart man.
