Wow, you didnt have to use a data link?by the way its torx 10 not 15.

[@GeorgeJohnsonJackofAllTrades]

Torx 10? Oops! Thanks for the correction. And, no, no data link. No mileage programming needed; the bike's computer (ECM) stores the mileage. But the new speedo will become locked to the bike's ECM after something like 30 miles (50km). So if you need to return the speedo, remove it right away...

I have Crusher Maverick 2.5 " slip-on mufflers on my bike and love them!

[@kenster007]

Yep-been trying for 2 days to set the colors and get rid of the gas gauge. Eventually I would have made it to the manual. Figured accessory mode is like the car-wrong. Super happy with the speedo/tach-always like to see rpm's. Can tell 4 things at one glance- speed, rpm, gear and clock without having to toggle. Thanks brother-nice looking bike too.

Thank you for making this video, just bought my wife & daughter an Iron 883 for their first bike, wondered about this tach, will install for sure.

[@TYMWLTL]

Excellent video quality. You answered many questions. And finally: Your 100% right. The Instructions given by Harley not just on this product but on others leaves one guessing. If it weren't for folks like you on youtube filling in the gaps for Harley accessories they would be selling a lot less product. Harley owes you a thumbs up. Thank you sir, be safe.

[@GeorgeJohnsonJackofAllTrades]

Thank you for the kind words.

[@coloradogrownHD]

Bought mine and installed it 2 weeks ago. I love it.

[@raulmondragon9603]

I too have a 2017 Harley Breakout, so your great video made this process very easy to follow. Great job in fully explaining the programing of this amazing tach/speedo. You're correct the written instructions provided in the package are vague as best. Thank you!!!

[@drsparwaga]

I’m glad I found this video by pure chance. I have this gauge on my Iron, and you are correct, it’s a very good gauge and good value for money, but the instructions are really lousy. If I remember correctly, it doesn’t even mention to hold the trip button down before the settings work. I eventually gave up figuring it out, and left the settings as they were. After seeing your video, I will give it another shot.

[@GeorgeJohnsonJackofAllTrades]

Do it! That's exactly why I made this video!

[@drsparwaga]

@@GeorgeJohnsonJackofAllTrades Bike is in the shop for some mods at the moment. Will get it next Saturday, and then do the same as you did. I let you know how it went.

[@drsparwaga]

@@GeorgeJohnsonJackofAllTrades I played around with it today, and it worked just as you said. Going to set the parameters later on. Thanks a bunch for this video. Really helped a lot.

[@drsparwaga]

@@GeorgeJohnsonJackofAllTrades I actually have a slight problem. So I set the settings to what I want them to be, and I am definitely saving each one of them before I go to the next one. When I turn the ignition on, and then off, and then on again to check whether the gauge has took my settings over, it loads my settings for a brief moment, only to go back to the original settings. Do you know why that is?

[@GeorgeJohnsonJackofAllTrades]

Make sure you test it in the dark.

[@jeremyspriet7955]

Thanks a lot George ! 🤘😉👍

[@joey13187]

Thank you! This was driving me crazy!!!! I could not figure out how to get into the accessory mode with the key fob! Not great instructions from Harley!

[@gmissile3365]

Request a point out of good restaurants in the neighborhood, as you test drive. 😂

[@GeorgeJohnsonJackofAllTrades]

That is a great idea for a video! This is an IOU...

[@SuperPalladium]

SlowJohnson!!! Love it! Okay, you wanted to know what we thought. Here are my ever so humble thoughts, just for you. First up, that opening video of you on the bike with the music pounding in the background was KICK ASS!!! Very Well Done!!! I see that you have a good grasp of transitions, and I was impressed. Again, very well done! At 1:20, while measuring the 3 3/4" diameter, it was very dark. You may wish to either wear a miner's light when showing this, or just add more ambient lighting, closer to the target; offers up a seamless product. When talking about the Tach, you may want to include actually saying the p/n, as this is a "conversation" with your audience. Loved the quality of your voice, and the normal lighting you used. The sound quality was actually some of the best I've seen on KZbin in these kinds of videos. If there was one thing that I'd like to see you do, it would be for you to show how you removed and installed the item in fast motion. Most tinkerers and mechanics enjoy that, even though they all know how it works and such, it's just nice to see it being done. By the way, I couldn't hear the subway at all in the back ground. Out of 10 thumbs ups, because I'm a fleshy-headed mutant, I give you a solid 9! Superior Quality Video!

[@GeorgeJohnsonJackofAllTrades]

Awesome feedback! Thank you for taking the time.

[@JasonT532]

What does it mean when I toggle through the modes eg. odometer, trip A and B, clock and the last mode shows an "R" with a number next to it?

[@Ragnar215]

I would like to see an actual insulation

[@GeorgeJohnsonJackofAllTrades]

Two screws and a plug. Too easy for a video. You can do it! This video covers the hard part and the questions Harley doesn't answer.

[@luxyclips9559]

How do you apply the settings i have the colors say saved and then when i turn the ignition on it goes back to white

[@GeorgeJohnsonJackofAllTrades]

Make sure you're checking in in the dark. It will always be white in bright light.

[@jonnymac8925]

Okay so, odd question? I have the tach in my 2018 Sportster, I also have the fuel sender because I have the master cylinder fuel cap that has an LCD fuel gauge built into it. The master cylinder fuel gauge works fine, but the fuel gauge on the tach doesn't seem to work. I got in an accident in November and after that the fuel gauge on the tach worked and it would also show miles to empty and whatnot but now it doesn't seem to work again. I'm confused If I am not programming it properly or not?

[@GeorgeJohnsonJackofAllTrades]

Is the on again off again all random? Or did it stop working after fixing the bike? Or...

[@jonnymac8925]

@@GeorgeJohnsonJackofAllTradesI guess I could try to reword my mumbo jumbo. I installed the master cylinder fuel gauge and sending unit reader and it works great, a few months later I installed the tach and all of the tach functions worked fine except the fuel gauge/miles to empty didn't register even if I set it to on in the setup. What I had thought was the tach fuel gauge and thE master cylinder fuel gauge couldn't both work at the same time off the same reading unit, but I got hit by an old lady, bike hits the ground and shuts off, when I turn the bike back on immediately after both fuel gauges were working at the same time, I had the master cylinder fuel gauge and the tach fuel gauge/miles to empty both working and in sync, then randomly about a week later the fuel gauge/miles to empty just randomly disappeared and stopped working (even if it shows its on in setup). I actually just went outside to the garage and unwired the master cylinder fuel gauge and I'm gonna fiddle with it tomorrow when I can start the bike without waking the neighbour's up at 2am lol

[@GeorgeJohnsonJackofAllTrades]

@@jonnymac8925 Wow. That sounds frustrating. I hope you get it working again.

[@jonnymac8925]

@@GeorgeJohnsonJackofAllTrades the plan is to completely disconnect the master cylinder fuel gauge, and to reset everything without it to see if it will recognize the Tach fuel gauge. If it didn't randomly work for a week, I wouldn't even be trying to figure this out, but now that I know it works and can work with the other fuel gauge I have some figuring out to do lol

[@linavictoriavelezlorza9487]

Hi George. Could you please to make a video with instructions in order to check, change, etc. the PIN for this model of bikke and speedometer. My bike is a FXSB 2015. Thanks

[@GeorgeJohnsonJackofAllTrades]

What a coincidence! Two days ago I went out to my bike and the battery in my fob was dead. I didn't even know how to access my PIN!

Hi George. Great movie, explained a lot to me. Say, has the new odometer read the motorcycle's mileage automatically? Does it need to be specially programmed?

No mileage programming needed; the bike's computer (ECM) stores the mileage. But the new speedo will become locked to the bike's ECM after something like 30 miles (50km). So if you need to return it, remove it right away...

@@wlodas1973 It is tricky. Took me two or three tries.

[@peterdouglas4073]

Does your speedo display gear selection?

[@GeorgeJohnsonJackofAllTrades]

It does. But in the manual they make a point of telling you it works by calculating the gear from your speed and rpm and that it might not always be right. I've never noticed a problem but then again I don't ride the clutch in second gear...
