Bonneville America Forums Forums Technical Forums Accessories relocating speedo to dash

i know its been done, taking a smaller aftermarket speedo and putting it in the dash unit, but cant find a thread on it though i thought one existed. Does anybody have any tips on doing this mod?

I think this would be cool also, but thought it would be very difficult to run the speedo cable to it. I'm interested to see what people have come up with.

This was a pretty big thread here for a while.
Keith did an awesome job with his. The thread is here .
Search and ye shall find.

If you need any help after going over the thread Chris pointed you to, let me know.

Thanks dudes.

If one would want to do this with a mechanical speedo instead of a digital, does anybody know the guage ratio for the stock unit?

2260:1 (I think that's the number, it's definitely not 2:1 or 1:1).

cool, thanks.

I think its 2240:60

That sounds better.

I did this

LOL it was scanning through the functions when the photo was taken.

i use a moto gadget mini which i bought for my america since i sold the trumpet i kept the speedo and fitted it to my sporty and works fine had to go to teach mode as it would not calibrate with the instructions supplied butthe best thing is it has a rev counter and everyone loves it as it looks trick

I can't believe no one just offers a bolt in kit for this.

moto gadget offers a bolt on kit for harley
they do a half moon version for triumph but is more streetfighter than cruiser

Here's my effort. I'm very pleased with the speedo, easy to set up, seems acurate, nice blue backlight and a very trick start up as the needle whizzes round to the end and then back again!! Photo shows it in tripmeter mode. The button to switch between mileage and trip is on the back, but it can be done with a remote switch which I will be fitting shortly.

Now there ya go... that is AWESOME!! And don't you just love the look of NOT having that stock speedo there? It just cleans it up soooooo much. And ya know... I now have this Lucus ammeter which I intend to install in the headlight bucket which would really class things up in a retro kinda way!!!!

Nice going!!!

Nice one,
is that a good fit in the dash and where did you get the switched live feed from.
I run a cycle computer on mine, have done for years but that would look so much neater and stop the MOT people asking why I only do 15 miles a year.
Cheers
Chris

cheers Glen,
couldnt remember what diameter the hole was in the dash, thought it was larger than 55mm.
KOSO do some nice looking clocks to fit in, may just be purchasing one soon.
Thanks for info
Chris

Bonfire Boy,

I have been searching and searching for a solution to move the Speedometer to the Console and it looks like you have actually done exactly what I want. I wanted to keep this an analog gauge and also make sure that I could continue to have a trip meter for fuel considerations.

Can you help us understand how you adopted the Koso to the Triumph? Specifically, what did you use for the speed pickup? If you went pure digital, what did you do to seal up where the old cable went into the front wheel.

This has risen to the top of my next mod and I want to start working on a solution.

Any help/guidance you can offer is greatly appreciated.

Thanks,
Steven

Also, any guidance on how much you had to butcher the tach is greatly appreciated. I hate to have to tear apart a perfectly good tach, but it appears that the mounting, the bezel and maybe even the cup are all valuable for this modification.

Again, thanks for any guidance.
Steven

On my dash mounted speedo I mounted the pickup at the rear wheel, thus cleaning up the forks a bit more by not having a cable or wire there. I glued the magnet to one of the sprocket bolts. As for sealing the hole in the front hub where the cable once was, I was luck enough to find some plastic bit lying around the workbench that fit the hole perfectly. Anything will do... a small cork, a whittled piece of wood or rubber, bubble gum, a spot of chalking. I then pointed that part of the hub assembly down towards the ground where the plugged hole is not visible.

Good News and Bad News.

First, the good news. The speedo came this weekend and I was able to get it mounted (and didn't have to cannibalize my Tach). The secret ingredient is a Carlini Paint Saver (PSP-4). I have seen references to the other models they have and that it had to be enlarged. I am happy to say that that PSP-4 works VERY nicely. It has a slightly larger opening that the speedo cup, but I wrapped a couple of rounds of electrical tape just below the speedo bezel and it snugs it up nicely. I was also able to use the existing mount that is part of the console by drilling a new hole in it to accept one of the bolts coming out of the back of the Speedo.

There are correct leads within the wiring harness under the console for always-on Power, switched Power, and Ground. Also, the remote switch that comes with the Speedo fits very nicely into the unused hole on the console.

Now the bad news....

I can't seem to get the speedo to work properly. I have all wires connected per manual and speedo sweeps to start and lights properly.

The problem is that I don't seem to be reading the speed correctly and I also appear to be picking up interference somewhere. Not consistently, but very frequently, I can rev the bike and the speedometer needle moves. Although I went through the calibration setup, I never see more than about 20-30 indicated speed. Mostly, the speed indicated jumps back and forth between 0 and 20-30.

I have completely re-run my sensor pickup wire a few different times thinking that it may have been picking up interference from the coil. I have also re-routed the main power cable (always on) directly to the battery.

Lastly, I have checked the sensor wires and I get a +5v constant on the power lead (as expected), I also see a +5v spike on the other sensor wire (not ground) as the magnet turns past the sensor. I don't seem to be getting any spikes on that wire from just revving the bike.

I am now at a loss as to what might be causing the challenge.

Any thoughts/suggestions are greatly appreciated.

Steven

Well first of all I'm really glad to hear you got the new speedo mounted up and looking good!! Nice one! But as for the problems you're having with it well... I wish I could help. Mine gave me no grief at all concerning the magnet and pickup. Once I dialed in the circumference of the wheel all was good. But your problem is just plain weird. I suppose there is a remote possibility it was faulty from the get-go. Is there a support # or a technical assistance line you can call for some help and suggestions?

Thanks for additional info...I have launched messages to Koso North America and I have also posted on a Koso European forums site. I have considered that there is a problem with the unit, but until I have some better information to go on, I am not sure. I am hoping to start a dialog with Koso so that I can get to the bottom line on what could affect this behavior and then keep on troubleshooting.

Any additional thoughts/pointers/suggestions are greatly appreciated.

Steven

Believe it or not, Koso NorthAmerican Technical support is on vacation for 2 weeks. Apparently, there is one guy in the Americas that can help. I am talking with others there and got some interesting ideas.

First, the main comment was that this is a Harley Speedometer and is not meant to be used on a non-Harley set up. When I mentioned that I have references of this speedo working on this bike, the conversation changed a bit.

I have a couple of things to try related to the interference issue.

Bonfire Boy,

One thing that would help from you is a little more information about the speed sensor you used. The one I purchased was called a universal Koso Speed Sensor and was about 1.5 inches long with Grey tip and Grey strain relief.

I have been trying a few different magnets and all of them appear to be signaling correctly because I can see the pulse come through on the wires as a +5V.

Can you provide any more information about the magnet setup that you have on your bike?

Any other thoughts are always appreciated.

Thanks,
Steven

Hi Steven, PM sent. I haven't got many answers for you though. Sorry!

Thanks...I at least have a couple of other pointers to go try. One is that I was only using one magnet so I am going to see what happens when I increase the number used. I am also going to try to run a dedicated Ground wire to see if that might help with what I believe is interference.

Lastly, I am checking with the place you purchased your unit to see if there is anything that is different between their bundled unit (with sensor and magnets) and th normal "Harley" version.

I hope to be able to dive back into this tonight and see if I can make some progress.

Steven

SUCCESS!!

After running a dedicated Ground wire back to the battery and adding more magnets (one per each of the 5 "spokes" of the sprocket), I have the Koso Speedo working. I still have a little more tweaking to do, but the speed seems to be close and the odometer clicks off miles very close to the mile markers on the highway.

This isn't the greatest photo, but I wanted to share the lastest view of this mod.

Thanks for the help and the ideas,

Steven

I've been watching this thread because I've been wanting to do this mod for a little while now. Keith's turned out so good and now yours looks great too. I'm glad it worked out for you...I had my fingers crossed for you and was hoping you'd get it sorted out.

Congratulations Steven!! Glad you got it sorted out... AND it looks fantastic!!

What bars are you running? I LOVE THEM!!

Norman Hyde "M" bars.

Love the speedo relocation. Looks sharp!

nice. i think i see my next mod. Sounds like the koso is the way to go.

Steven, I really like the solution you found to relocating the speedo. It's clean and straightforward and does what it's supposed to do without too many bells and whistles.

I would like to do the same for my '04 America. Can you point me toward a dealer's website?

I found a 'KOSO' site but couldn't locate the speedo you installed.

Thanks...
