In my opinion if the flywheel is disintegrating you would have a clogged oil filter and be throwing oil and code lights, and a vibration would defiantly be noticed. A second opinion is needed.

 

Thanks to all who responded. The engine is torn down and I am doing a long block replacement. I have seen the trashed cylinder walls/pistons as a result of the metal bits floating around. I have babied this bike since purchase, oil changed every 2k with synthetic and all other recommended service. I am told the damage is the result of overheating causing the bronze bushings to give way. I am extremely disappointed in HD. The bike was not ridden hard, but I did have a 2 hour slow ride through Houston on my last trip. Even then, the bike showed no signs of overheating. But the research I have done seems to say this is an inherent problem with the 103 motor. I will put an oil cooler on it after the rebuild and hope for the best. This will be my last Harley. Once again, thanks to all.

 

Sorry to hear this news. Since there were "no symptoms" I did not think it was serious.

Once you get it rebuilt, there are things you can do (an oil cooler is not enough in most circumstances) that will keep the Twin Cam cool.

craziness, sorry bro.

 

What bronze bushings are they claiming failed from overheating?
And what do they claim caused the overheating?

 

The bronze bushings are on either side of the flywheel. And they are not sure of the overheating cause. I am not technical enough to be 100% sure of the cause. i have only seen the effect.

 

It just doesn't add up to me.

 

I kind of agree with this also BUT what I always do is build it better., get it balanced, etc... This way it will be BETTER than new! Keep receipts and then sell for more if you like. (Did you change the oil when you bought it?)

 

Good advice. A friend of mine had a Road King doing the same thing on a ride to the mountains. He checked the battery connections and found one loose. All is well now.
