Default Not so much tubeless but sealed

I sealed the rear laced wheel on my bike.
The thought is if I get a puncher out on the road, I would have the option of plugging it.
Here's to hoping I never find out if it'll work.
fyi - There was a surprising amount of surface rust and flaking paint on the inside of my bike's rear wheel.

A link to video of what I did.

Brought the bike home finally after being in the shop for almost 3 months.
260 Cruisetec rear tire, I was right, it adds a notable amount of ride height.
Unfortunately the new bars, LA Choppers Valley bars, are not comfortable. It may take some time and adjustment, but I don't know if I'll be able to get a comfortable position with them, so I may need to build my modular handlebar setup.
Glad to have the bike back.

If you remove the cat the bike will run cooler and have more mid-range power.

the bike will run cooler but its been advised to myself from a reputable tuning company that removing the cat on m8s is not advised if ypu want it running well.Im guessing due to back pressure.

Traded in my 2021 Heritage for a 2023 Heritage; the blue and gray color combination got me

DKCustoms proved that the M8 engine does not need to be retuned for an exhaust and airbox swap. The ECM adjusts and handles it easily.

If you say so.

I don't "say so". DK Customs did a series of videos with the evidence showing it.
This isn't an opinion, this is quite literally the end result of their testing.

It's how the scientific process works.
The hypothesis: You need to retune a harley if you swap pipes or airbox or both
Test the Hypothesis by gathering data via Temperature and Dyno testing after swapping multiple bikes from different model lines
What is the end result
EVO: True
TwinCam: True
M8: False. M8s do not
Additional findings: A stage 1 tune will add more power than the ECM will adjust for, and certain exhaust systems will create torque dips and problems that can only be resolved by a tune. A Proper tune can get better than stock cooling.

So in short DKCustom's experimentation yeilds data that shows that the M8 is not like the TC and EVO, that they do not run lean from the factory and can be muffler and airbox swapped with no risk of harm or damage to the bike without a retune.

I dont trust them because they said it and are nice people... I trust them because they put in the work and effort to test their hypothesis, and showed their work, and their testing proved themselves wrong about needing to retune, so they changed their stance. I can trust them because they can show me the evidence and I can come to the same conclusion.
