With the bike idling in neutral, you'll hear a whirring noise; mine sounded like spinning a metal rollerskate wheel, or a metal rollerskate wheel on a concrete sidewalk. If you're too young to remember metal rollerskate wheels, it also sounds the same as a bad throwout bearing in a [manual shift] car. Ask an old-timer to listen to it and see if he says it sounds like a car's throwout bearing.
Pull in the clutch and listen for the whirring noise to roll to a stop. If you kick it into gear, the noise will stop immediately. Tap it back into neutral. Roll on a few hundred RPM above idle (not needed if it's really bad/noisy), and dump the clutch. If the noise spins back up, your IPB is toast. My second failure wasn't near as loud as the first time, but a tear-down by the shop still showed metal transfer between bearing/race, and heat discoloration.
If your noise is that loud, roll the dice and tell 'em you want it torn down and inspected; you pay the labor if it checks out good, they pay and FIX IT RIGHT under warranty if it's bad. That's what I had to do the second time...Tech said same thing, "All Dynas sound like that"...Bull-shevik! You know your bike! Most shops are IGNORANT of this issue. Educate them. Point them to my thread "Finally, Good News..." Good luck, and keep us informed. Call Milwaukee Customer Service FIRST to establish a "Reference Number" that your shop can use to deal with Milwaukee.

Hmm.. thats not good man. There's been a lot of talk lately about this Baker IPB that's supposed to be really good. Perhaps order the part and tell your dealer to replace it with that if they will? I don't know what to tell you man.. maybe you should let me ride your scoot to see if I can hear it?

This was/is primarily (pardon the pun!) an '06 issue. When they came out with the six speed for '06 Dynas, someone decided that alignment dowels between the IPCase and tranny case weren't needed. If the factory got lucky and assembled things properly aligned, an '06 owner may never have a problem. Others of us have had multiple failures when HD just replaces the bearing and race, and doesn't correct the underlying problem. I've read of one Forum member who's had 4 failures. When HD fixed mine the second time, they upgraded me to '07 IP & Tranny cases. Topspin having problems with his '07 is unusual (he SHOULD HAVE doweled cases), but not unheard of.
Top; I'd ask to verify you don't have leftover '06 cases when/if they tear into it.

Also, the last run of 06's got the doweled case. There werent any holdovers going into the 07's (that I know of, but I could be wrong).
Tony, the dealer isnt going to tear into it under warranty unless they have a damn good reason to, and know they can find a problem. If the race isnt the problem, theres only one other bearing that possible could. And thats the mainshaft bearing between the mainshaft and the input shaft. Supposedly the dealer says they replaced that?? The input shaft has a zero tolerance when installed, and if theres any wiggle at all, its gonna make noise. The only way to know is to tear it apart yourself, and if its screwed, take it back to the dealer and shove it up their a$$ for not doing the warranty work they said they did. Wont be the first time I seen them screw it up. Had one dealer put the rings in upside down while doing a big bore upgrade. I didnt think that was possible, but they proved me wrong.

That's why I had to roll the dice on my second failure. Tech said it sounded normal. I knew there was a problem, so I gave the OK for them to tear it down with the understanding that if he found all within spec, I'd be on the hook for about 3-4 hrs labor for them to chase a "non-existent problem". I know my bike, and knew the sound was NOT normal, so I told 'em to tear into it. I was proved right, and the subsequent repairs were picked up by HD.

My '08 Ultra is in the shop all week with this same apparent problem. I have 25000 miles racked up as it is my daily commuter (120 miles to work and back) in the one year I have owned the bike. Same symptoms, at a stop and engage first with clutch in, sound goes away. I think I can hear it at speed, clutch out and in gear. Waiting for a bushing to arrive, hope we get it cleared up. I like my local shop and hope they are on top of things....
The problem only surfaced about 1000 miles ago or so, but got so bad I had to take it in for second opinion.
Seems like most of the information suggests my '08 shouldn't be suffering from this problem, but who knows. Mostly hoping I didn't do any further damage waiting to take it in.

Patrick, thats a misnomer. If the tech doesnt see any visible damage to the race, it wont get changed. Got proof on that one.....
