Has anyone had there new 110 motor tore down from excessive noise/Piston Slap or clacking sounds at idle after the motor is hot? Has your dealer made good improvements from tearing into the motor to check clearances/tolerances and repairing those issues? I just took a 2500 mile trip and have 5800 miles on the new 110 motor and things are quieting down and the motor is running strong except when it gets hot at idle it makes this loud clacking noise that is not the primary and my dealer has offered to tear the motor down under warranty and check all tolerances and make it right. I guess I ask this question because I will be without BLUU for at least a month and that makes me sick inside.
I know you say it isn't in the primary, but I wonder how you know that? Has anyone taken a mechanic's stethoscope and actually tried to track the noise down? How about when it's making this noise at hot idle, if you pull in the clutch, any change in the noise? In gear versus in neutral?
I'm not sure what kind of piston slap your dealer has had any experience with, but in my experience piston slap is worse when cold before the piston expands from the heat. Maybe Harley has a new type of piston that shrinks when hot? Nah, didn't think so.
One thing that happens when the engine is hot and at idle is that the oil pressure tends to be at it's lowest. Low oil pressure and the lifter problems others have reported might lead one to think your dealer should be looking first at valve train issues before tearing the entire engine apart. Once again, have they isolated where the noise is coming from, or are they just making wild guesses, or are they possibly just messing with you? I've seen places tell a customer things like "we can tear the engine down completely and look around" when they have no intention of doing so. The assumption is that a customer will never want an engine completely torn down by a dealership, and will quickly decide to just keep on driving it as is. It's been an effective way to get rid of complaining customers in the past. I have no idea if your place is one of those types or not, but when you stated in an earlier post that the "master mechanic" said
he knew what it was but wouldn't tell you, and to just go ahead and ride it, I had visions of someone just trying to get someone out of their hair for a while. And taking a month to do this "teardown and inspection", come on. What's the plan, remove one part per day?
BTW, it would be exceedingly rare for H-D to approve a fishing expedition under warranty to just tear everything down and supposedly measure parts and verify fits. They tend to only approve the minimum necessary to fix a verified problem. So unless this dealership just has techs standing around with nothing to do, I can't help but be a little suspicious. I realize I tend to be a cynic, but that cynicism has roots in almost 40 years experience dealing with auto and motorcycle dealerships as both a customer and a "factory guy".
