I checked ARP I broke 8 of them turns out when you do a stage 3-4 you over tq them if you use the manual. that's why I kept braking them

Bike is in the shop. Will be a week or so. Will let you ask know how this goes and what the outcome is.
Honestly, I am thinking of selling it after repairs, who knows. It is paid for so why not keep it, but why keep something that is showing signs of not being what you paid for?.
I hope this is not an every 10k miles event. Another reason not to hang onto it.

I'm going to buy an extended service plan from a sponsor we have ( discountesp.com ) for another 5 years and ride the **** outa mine. I'll get the tune I want remapped either by another dealer or an indy shop and be about my business with it. One thing I've learned over the last 40 odd years dealing with harleys and motorcycles in general is nothing is bullet proof so enjoy what you like and deal with what if's if they arise.

Understood. Nothing mechanical is going to last forever.
I am having difficulties with the only 16 months and 9078 miles before failure.
I work on very large, complex machinery that operates for many years without concern, barring electrical concerns that do arise.
Perhaps this is why I can not wrap my head around it.
$18000 any takers

You haven't taken the bike back yet? Maybe it something simple like a damaged plug wire / closed plug gap?

I wouldn't worry too much about these rocker box gaskets. I had one spring a leak on my brand new 2016 FLHTCU, just a couple weeks after I rode it out of the dealer.

I knew replacement wasn't complicated so I did it myself rather than take to the dealer shop. New gaskets are cheap. Parts come off and go back on easy. There must be a lot of give in the parts because on my 2016 I wasn't able to get a torque wrench onto all of the fasteners. I guessed, using my calibrated elbow. It never leaked again in the following 35k miles.

Why they leak from the factory is probably due to sloppy work by the assemblers. I've found several things on my 2018 RGU that are due to plain and simple sloppy work at the factory.

Been a mechanic all my adult life, bikes since I was 16 this isn't some low grade mechanical issue it's a timing curve change and they are playing the dummy up about it.

So have they ridden the bike? What did they say?

Been working on bikes since I was 15. Did it professionally for 10 years. Have seen all kinds of issues on both sides of customer / service dept.

Check for an intake leak? Buddy had one that idled fine but had reduced power at about mid range and above. Cracked intake. He had just had the heads off....

Good point, The plastic intake manifold has had issues.
