I got back from the dealer and have some more information but not necessarily a clear understanding of the root cause of the failure. I suspect that the root cause had to do with an issue on the quality of the upgrade labor and either an oversight or poor assembly.

They found two distinct problems. My original complaint about the noise appears related to damage of the tappets (no idea how that happens). That, in turn, seems to have caused some markings/wear on the cam. So the replacement parts include;

2 Tappet Cover Gaskets
2 Exhaust Pushrods
2 Intake Pushrods
4 Roller Tappets
12 various O-rings including filler plug O-ring (?)
1 Cam Drive Sprocket Retention Kit
1 Camshaft Cover Gasket
1 Needle Full Complement Bearing
1 SE8-498 Power Cam
1 SE/Twin CAM Tappet Kit

The second issue found and covered under warrant was a Top End Leak with parts needed;

4 Rocker Cover Gaskets
2 O-Rings (various ID)
2 Coolant Manifold O-Ring

So, I won't see the bike until the end of next week. In the meantime, I ordered a Fullsac MX Header and the HD Auto-Tuner so it can be installed as part of this whole dealio.

Man, too bad you don't have another bike to ride while this one is in surgery and recovery...... ;D :2vrolijk_21:

Don't like to hear things like this on anybody's bike.  Good luck with these repairs, Simon.  Hope the HD Auto Tuner does well.  I'm interested to see how you like it but sad in the way you had to get it...

May just have to ride one of this German bikes for a while. Oh well.

The tuner was a choice, just like the header upgrade. After putting 10k miles on the bike in 5 weeks I found the bike lacking in "grunt" and top end speed. Climbing steep sweepers in the hills/mountain of Oregon was disappointing. The speedo would not hold speed unless I downshifted. I figure the header/tuner combo should help that a bit. Maybe a good solid install with help too.

A tech friend of mine tells me that the M8 (107? 114?) tops out at about 105mph at 5800 rpm. Anyone have any experience in that area they can share? I was used to the 110 TC being able to eventually climb to 115-120 mph range.

It's actually pretty common for vehicles including motorcycles to come with electronic "governors" these days.  I believe Harley started doing it in 2014 with the RushedMore bikes, but if that's wrong they most definitely have been doing it on the M8's since day one.  Once you abandon the street legal Harley tuning device for a full featured but illegal system, you can change those speed and rpm limits.  I think I'd wait on that until I knew I wouldn't be needing the warranty, or stopped caring about the warranty, whichever comes first.

What Jerry said....also for at least a couple of decades in the automotive industry the norm has been that the top speed limiter has had everything to do with the speed rating on the factory stock tires. Back in the 90s I sold a buddy of mine a brand new Tahoe. On his way home he found a stretch of open highway and when top speed was 98 mph I got a phone call. So I checked the speed rating on the tires and guess what it was? Yep 100 mph. I don't know what our tires on our bikes are rated but I would assume that the 105 mph maximum speed chosen by Harley will "supposedly" have something to do with our safety. ???

Anyway good luck Simon and thanks for posting.

Harley uses H rated tires, which is 130 mph max.  The one thing Harley does right, IMHO, is using tires that have higher load ratings and speed ratings than absolutely necessary.  When it comes to safety, I like my tires to be under-stressed, not on the ragged edge.

Why in the hell would anyone want to go over 100mph on a Harley on a public road?  Maybe I'm getting old but anything above 90mph on one of these 2-wheeled lawn mowers is dangerous.

No, but I have ridden across the plains several times, steady at 90mph.  Engine had a little bit more, but the suspension didn't.

If it's too fast or too loud you're too old! lol

I couldn't find what the H rating equated to Jerry, Thanks. And I agree completely with your statement, as per usual.

Good luck Simon!

The M8 is governed to 107 mph, the 107, the 114 and the 117.  The HD warranty legal tuners will not remove the speed governor or the rev limiter.  I know the TTS tuner will for a fact.
