Universal digital speedometer

Mine came with directions that were decent I guess. The set up can be a little daunting at first but it's easy enough once you get the hang of it. A couple tips to save you some aggrivation....the speedo pickup magnets work best in a tight circle rather than spread out in a wider diameter on the brake rotor. Also, while calibrating the first perameter wants you to enter tire circumference in cm and that'll get you pretty close. I then rode with a gps speedo app on my phone to compare and was able to fine tune it by raising or lowering that tire circumference a little at a time then checking again. The tach would not work when I put it on my coil as instructed and I suspect it's because of the cdi ignition, because when I put it on the positive lead straight off the magneto it worked fine, though not accurate as it's a 2 stroke and these are only good for 4 strokes as far as the tachometer goes. Otherwise, wiring directions are on point and keep in mind, for neutral and gear indicator wires, they're looking for a negative signal not positive so if your neutral switch sends a positive signal it may need to be rewired to work properly. Everything worked great though, high beam indicator, turn signal indicators, and marker light indicator all work great, even if the speedo itself isn't powered up so it saves a little power if I only want my indicators.(I didn't wire mine to the ignition to turn on immediately, I used a toggle instead as my set up doesn't have a battery originally. All my lights were added by me and run off a 12v LiFepo4 battery so my electrical set up is a little different. It also keeps it's settings and odometer memory when the battery is disconnected which is awesome since I pull my battery to recharge when needed on a bench. I actually started with 4 stars and as I wrote this review I couldn't really think of a reason not to give it 5. I feel the speedometer pickup sensor was a little touchy at first, but once I tightened up my magnets pattern and got the sensor as close to them without touching as I could, it works perfectly fine, just takes a little trial and error to dial the calibration in perfectly. There's a couple YouTube videos on installing these, but if you know a little about wiring it's fairly easy to figure out. And the included mounting bracket was very much appreciated. All in all it was a great deal for a decent all around universal gauge with all necessary indicators, even a fuel gauge. Which will blink if not used and if you're like me this may be a minor annoyance. Run a hot to the fuel gauge wire (only if you don't have a sending unit and don't intend to use that feature anyways),but be sure it's straight from the battery with a 5a fuseable link or inline fuse holder with 5a fuse and not sharing a circuit just incase you wouldn't want this thing to blow your fuse on your taillight circuit at night, I haven't blown a fuse, just not taking the chance it might. You're welcome because if it does what mine did it should just read full all the time now and no more blinky blinky. I would recommend to anyone looking to have a functioning gauge and set of indicators for a reasonable price. It's not fancy, but it works and doesn't cost a million bucks.UPDATE 10\29\21I love this thing. It took a little patience and trial and error while comparing against a GPS speedo app on my phone, but I was able to get it calibrated perfectly. It didn't take long once I took the time to do it right. I entered the circumference of my tire in mm's and that got me in the ballpark, then I just would ride, see how far off and which way and change my number slightly up or down accordingly. Got it dialed in perfect within a few tries and all is tight with the universe. I like that it holds it's settings even when there's no power because I don't have a charging system, so for one, I have to pull the battery and bring it in to charge once in a while. But also, I have a main battery switch to completely cut power to everything in case I forget to turn something off and have no lights for my trip home. The speedometer always remembers my settings and had remained accurate for months, I still pull up the gps speedo app from time to time to make sure, and it's still spot on from 1 right on up to around 50 or so where I let off because huffy beach cruisers weren't built to go that fast... I'm planning another build soon, and already have this guy on my list of materials. There's a very slim chance of me not buying another, and maybe even a 3rd for my girls bike too. Speedometers all around!!!

I gave it 5 stars because i got everything to fit up and work correctly. when entering the modes to get to your settings do not forget that if you change your tach from 1 cyl to 2,3, or 4 it will never go back to 1. Also when it says to hold for xx amount of seconds its not all that accurate, try a few different ways itll work. when i entered my tire size the spedo was way off but after a few times dialing it down its with 1 mph of my gps. it said to use 2 magnets for the spedo but that made everything all wonky and i found out i could swith the settings to use only 1 magnet. i did that and it works perfect. I was worried about the magnet flying off the rotor so i put a small dab of epoxy on it, no problems. turn signal and high beam indicators work great. have not used the gear indicator or fuel guage.5 stars

Junk do not buy. Wiring diagram not correct and speed sensor did not work right out of box. Also seller will not do anything for you but keep asking you questions about how it was installed and then tell you to deal with Amazon exchange. Spend more and save yourself the trouble.

UPDATE:First, I misplaced my install instructions and the seller was quick to send me a PDF version! I have it installed on my bike and everything works (except for fuel gage because i don't have one - no biggie and the gear indicator because i don't have that either... only Neutral indicator). Had some trouble with the actual speedometer reading but after pulling out most of my hair and exercising my sailor language, I discovered 2 wires reversed. More than 25 years experience and such a rookie mistake.Second, I used the light indicator to show if my auxiliary lights were powered on, not my headlight. Left the bright indicator as intended.Lastly, I'm not sure why there is a separate input to supply power all the time to the unit from the battery when there is also standard power input from the bike key-on relay. That's the one I used to power my unit. I thought maybe this secondary straight power input is needed for the speedo reading... but when I used a jumper to get power, there was no change.I really want to like this speedometer so I hope it works good for the foreseeable future.ORIGINALInstalling this now and while it comes with matching connectors for your install ease.... it does NOT come with pins for them. I'm playing the guessing game trying to order pins for the connectors. Will adjust rating after installation.

So far not too bad, just trying to work out the tachometer is a bit of a pain, i wish I had some ideas on that. Got it knowing that it would be a project, so cant complain, but if the seller has any tips for rpms that would be great

The media could not be loaded. Got it all hooked up on the mini Jeep. Working great. 100 ohm resistor for the gas set at 3 for the RPMs had to run wire directly the spark plug wire Black with the yellow stripe .If wire is not insulated. You will get interference from other wires. Finally miles per hour struggled at first. I'm an idiot kept trying to put in tire size 🛞 x 🥧=👍

I installed the speedometer on my custom 82 Honda 650 bobber. I had no trouble with the instructions. I used only some of the wiring as I do not have turn signals, fuel gauge, etc. I cut the plugs of the speedometer wiring and soldered and shrink tubed to my existing wiring. Programming was simple, after I guessed the “perimeter” setting is your front tire circumference in millimeters (tire diameter x 3.14 x 25.4). There’s a small reed switch you mount near your front brake disc. The kit includes two very strong small magnets that stick to your disc and are sensed by the reed switch. I used both magnets and programmed the speedometer to know each tire rotation would send two pulses to the speedometer. Total install and program time about 90 minutes. Nice having a modern speedometer on an old bike.
