Are there any "reliability" issues with the new M8s?

M8wise, It sounds like they have the weak links (cam chest) taken care of. Of coarse there are many "enhancements" available so if you plan to leave your machine untouched you'll need to stay off of this site and the internet for that matter. LOL.
Do you plan on leaving the exhaust and tune stock as well?

I ordered the orange and black one. I'm doing my best to keep it stock so I can enjoy having a warranty, at least for a while.  ::)

I'm not sure what I'm going to do about the exhaust yet. I'd like to get rid of the cat and the associated heat, if I can. The dealer says he can let me get away using aftermarket (Fullsac) exhaust and he says he can tune it with the SE pro street tuner and keep my warranty intact but I'm doubtful the tuner has the range necessary to do a proper tune. Has anyone here done that successfully?

Along the same lines, has anyone tried ceramic coating the stock head pipe to control heat?

I have fullsac baffles in my stock slipons and no tune was needed. Last year, I was riding 2 up on Pike's Peak in a warm July day at the base of the mountain and caught in the endless crawl to the entry gate. Saw couple of bikes pulled to the side because they had to be shut off to cool down. We just kept rolling as our engine heat on the 2021 never got like that. Now the 131 I did on the 2017 could put some heat out in the summer, probably why Im never going that route again.

Congrats Joe! That orange is one sharp looking bike, I saw one at my local dealer last week. I've made sure to stay away from the dealership since then.

Depends what you mean by "Fullsac exhaust"? If you mean headers than I did try with the Harley tuner (or the tech and the dyno tried) and it can't be done due to the limitations of the Pro Street. If you mean the slip ons then you dont even need to re tune.

I was talking header and you confirmed what I thought. Did you put fullsac cores in your mufflers? If you did, did you notice any difference in sound or on the dyno?
