I know the bike won't explode without a real tune, but it's messing with my head riding around on this EPA tune. I've heard mixed opinions on this, but if I were to buy a PowerVision system and save the stock map, then have the bike tuned, is it possible to flash the ECM back to the stock map with no footprint of the previous tune?
Part of getting a new bike was knowing where all of the miles came from and having that warranty. If it's not possible I will just wait to have the bike tuned after the warranty expires. Thank you!

The folks at Vance and Hines told me that even if you flash back there are still signs that it has been reflashed for example a date stamp that shows when flashed back.
I have never used one but on a brand new bike you might consider Thundermax. They use a whole different PCM and you keep your stock one. Then put it back in if there is a need for warranty work. Assuming you are not broken down far from home... That's another can of worms...

You may hear differently from others - my understanding of this is once the bike has been tuned by PowerVision, the bike will record that & your power train warranty will be voided.

I appreciate the info. I will just wait to get a custom tune when the warranty is done. The bike still feels fine, and it says the Thundermax doesn't fit 2020 models with traction control anyways.

I bought a used ecm from ebay that was off of a wrecked bike of the same year and color as mine. My dealer flashed it for me to work with my bike. I loaded a power vision tune on my factory one and swapped them out in the parking lot whenever I took the bike in. Never had an issue in 2 years. Pretty much the same thing as Thundermax does I guess.

Old school good dealer there. :2vrolijk_21: :2vrolijk_21:

For several years you could flash it back to stock with a power vision or a TTS and HD could not tell. They then set it up so they could tell it had been flashed. So the trick then was a TTS or Power Vision, and a Harley SE tuner. They now have a record of it being flashed with the HD stage one Tune. Tune with TTS ride, if it needs to go to dealer put HD Stage one tune back in. But starting in 19 they can now catch that also.
Second ECM or Thundrmax is only way they can not tell.
My bike power train warranty will be void next time they hook up to the bike. Not to worried as I put 20K on the bike before I messed with it. The dealer knows the motor is built. They are still covering non related items. Waiting for service to open back up so they can install my new front rotors and these are warped, my new speedometer and such.

Dave,,,, didn't you do front rotors already? I had mine replaced on my 19,, what's the deal here? 😩

Yep. They are a good bunch. Bought last 3 bikes from them. Not a single complaint from me. Always give me a 20% or better discount on parts and service and have extended it to friends if I ask them too. Harley should trying going back to the old way of doing business. That business plan made them money and kept customers loyal.

I’ve been down that road with warped rotor(s) on my 2017 cvo, have the shop check the wheel mounting points, some wheels are not true and a new rotor will be warped as soon as it’s installed and you will feel it quickly.
:soapbox:
Sorry, getting on a tangent here! LOL

The margins are so high they could stand to do this and be ok. Like Kohl's for example. List the price of a blanket at 150 bucks, put it "on sale" for 75 bucks over "friends and family weekend" to make people think they are getting a good deal and still make a killing on a 15 dollar blanket.
Harley can squeeze the life out of people who don't bother haggling, and then give the occasional 20%+ off to those who try to bargain a bit and get praises from the hilltops for it.
Sorry for going off topic in my own thread ;D

Replaced at 6K miles, replaced again at 14K miles. Warped again at 20K miles service. That said rotors came in at start of covid-19 so not installed yet. I'm over 25K miles now, and would soon be on anther set if these would have been replaced right away.
I can not figure it out. 09 CVO RG is the only other bike to have a rotor replaced and that was once in 47K miles. my 7th 6 CVO's have never had a rotor issue.

Front rim was replaced at 19K miles with another factory rim. Ill have them check mounting points when they install new rotors. Thanks

Mine were replaced at 6 k. First time for me that I had to replace. Cheap harley crap??? :'(

on my 16 cvorgu i had the front brake pulse (warped rotor) i thought, they replaced front wheel bearings. it fixed it and still has same rotors from new and no issue since. somn to ask them about :nixweiss: :nixweiss: ,,,sorry :jack:

There is a new wheel on the front with new bearings. Rotor still warped in 5K miles.
There is some underlying issue I am sure. Harley is just fixing the symptom, warped rotor. Not trying to figure out why its doing that. Looks like the same rotor that is on my wife's 2019 RGS.

I had a 2008 SERG that warped the front rotors as well as wore the front tire out about every 8k miles. After the rim was changed under warranty the warpping improved to every 8k miles. Yep, those extended warranties pay for themselves for people that ride. No issues on a 2010 1/2 CVO Ultra and no issues on a 2015 CVO RG. Actually plenty of issues on both of them but no rotor issues. If I went down memory lane the 2010- 2 sets of lifters, 2 cams, ABS module went bad, and oil leaks. The 2015 with the 117 kit: spline on clutch hub, water pump while at Sturgis( trip was ruinend), One set of lifters, Crank bearing while at Panama City which caused a total motor rebuild including new cylinders, Pistens, oil pump etc. But the bike did have 27k miles on the clock so it was due right HAHAHA( yes 2nd trip in a row ruined). We keep buying them why???? And the motor company is loosing market share and need to publish on how they are going fix the company. Start by learning from the competitors WHO's bike perform right off the showroom floor and 100k without major issues. HD doesn't need a sales strategy or a new model that requires tooling and Capital expense to launch, they need quality!!!!!!

I was told today (6/29/20) using anything but the Harley tuner will void the warranty. Was shopping for full exhaust on 2020 CVO Street Glide.

SAME thing on my 2008 SERG. Warp rotors about every 8k and front tire tread would cup and wear. After 3rd set of front rotors the dealer replaced the rim under the extended warranty. Of course it did not fix the problem. So I upgraded TO 2010 cvo ULTRA- TOO MANY PROBLEMS TO LIST ON THIS BIKE. Next was a 2015 CVO RG. Did the factory 117 upgrade at 10k then water pump failure at Sturgis and 15k , Crank bearing failure at PC rally with 20k. Thank goodness each bike was covered with Extended warranty. My first HD was a 2002 Dyna Wide Glide- 28k of trouble free riding. Guess CVO have special needs!!!!!!!!!!!
