They are as cheaply manufactured as possible because Harley knows that few will achieve the comparable mileage of the car sitting next to it in the garage.

Softy simply wore his out. Check his thread on the rebuild and learn.

Google Timken Lefty bearing and see what a strong crank looks like, It's still available in the Screamin' Eagle Parts Book under high performance section. And standard on Twin Cams 99 -02.

For example I have a 1999 FLHTCUI and a friend with the same bike since new. I was talking about the issues with the cam chest ( I lost mine at 50K) and she explained her engine was torn apart at 100k just for kicks. She was doing the big bore and cams at that point and the shop was shocked that it was that good on the inside.

Some of the bikes don't get the right oil, sit to long and who knows what.

Sorry OP that your bike has problems. Get her fixed and keep going.

I became very worried about my bike ('09 Ultra with 45,500 miles) since it had the same symptoms as the OP from the thread link above. I dropped off my bike to the dealer who said so far my IPB is shot, the "compensator is showing wear", and "the tech said he can hear grinding just by turning my rear wheel by hand". They're tearing into the transmission to diagnose for sure what needs to be done. So far I've authorized three hours of labor to diagnose the issues (the labor will be part of the repairs, not in addition to the repair)

I'm really upset about this repair - my local dealers are all owned by the same people and while I trust their work the pricing is often high. Labor in Vegas is high in general at about $100/hr. I don't have an indy that I trust. I know there are a few around but I don't get a good vibe from the couple I've spoken to in the past so I'm kinda stuck with the dealer since this isn't a repair I want to or have time to do on my own.

A well maintained 45,000 mile bike shouldn't need this much work.

I'll post an update when I have one

Yeah, 07's were the worst, but search Harley crankshaft runout on Google and stand back and prepare to be amazed ( or depressed.) You can stand by your statement, but the facts ( and a couple dozen posts) say otherwise.

No Kool Aid consumed here.
