Calling All Dealers!

If your interested in becoming a dealer for Speedway Instruments send an email to

Dealers should have a shop in which todo installations, and agree to sell only at MSRP.

Initial purchase is required.

Single-Fire tachAdapter Available

So by popular request, I have made the Single-Fire tachAdapter available without the purchase of a microTach+ tachometer.

This will enable you to use other standard aftermarket Tachometers available on your 2004+ Harley Davidson motorcycle. Including Sportsters, Roadkings, Softails, and Dyna.

See for details.

Here is a new video showing the microTach+ tachometer in action hitting the redline while cruising down a nice road.

Moving to Blogger

I have decided to try and use Blogger for the Speedway Instruments - Development Blog. Primarily because I am hoping it will be easier to maintain and update. Over the next weeks I will be moving all the old stuff over to this site.

Speedo/Tach in development

So I've been working on a Speedo/Tach combo design. Like the microTach it will be very small but contain everything you need including indicator lights, and odometer. I am targeting custom applications and people who don't want the speedo to be a primary attraction on your handlebars. It will be the smallest speedo/tach available. Stay tuned for more details, and sign up for our newsletter to get automatic updates.

Comic Life Installation Instructions

I am trying a new thing. I used ComicLife by plaq to redo the nightster installation instructions in a comicbook style. I think its cool. Let me know what you think. I may do this for all the instructions. Click Here

Tach adapters are Here

The tach adapters are now available with installation instructions for Single and Dual Fire ignition systems. They attach directly to the coil inputs and filter the signal suitable for connection to a microTach+ tachometer.

Don't worry about size as you can see from the photo, the adapter is not much bigger than the wires and will hide easily away.

I haven't updated in a while, so I thought I would post some of the latest developments. I have PCB's now for the tach adapter and hope to build have them on a bike tomorrow. After at least a week of riding then I will start shipping. The adapters are just noise filters to make the signal acceptable to the microTach+ Tachometer. The actual microTach+ model is the same as the one for 1999-2004 Twin Cams. Also, I have started on the All-in-one Speedometer. This is going to follow the same Small is Better approach and expect it to be smaller than 2" x 1" But still have all the features you need like Speed, odometer, trip meter, and indicators. I will try to keep you posted on developments.

Tach adapters delayed

Due to some difficulties during testing the tach adapters are being redesigned. This will result in delay of the coil take off models which would support all bikes Big Twin's older than 1999 and sportsters older than 2004. I am sorry for the delay.

Chrome is Here

Due to higher cost of finishing in chrome the cost of chrome finished is increased.

Mechanical Drawing and update

Now I have tinted lens over LED display. Provides better contrast and looks better. Chrome is ordered, and so are electronics with 36" leads. Delivery is expected within 3-4 weeks. I will be at Republic of Texas Rally May 31-June 2.

Mechanical drawing of case is available

Anodized Case

New improved Case! In about 2-3 weeks I will stop selling the molded microTach and start shipping an improved version which has an aluminum case. This will be available as black anodized or Chrome plated. Here are some pictures of raw prototypes. Finish quality will be much better in final product, but as you can see the overall look will be more uniform and smooth. The size is actually slightly smaller than original.

New Aluminum Cases!

I wasn't satisfied with the molded microTach. So I finally did a 3D case design and got it machined by
REF Machining.

Diag Port Connector

Today I tested the microTach on a Softail Deluxe. It worked great. Therefore it is confirmed that the microTach will work on all TwinCam's with the J1850 serial bus. Which are all models 2004 or later. Also, all HD 2004 and later use the DT-04 connector, so if you want to use as a temporary install for diagnotics or tuning. Just add the connector and plug into diag port. There is a link on product page to a vendor.

The Molding begins

I will begin selling the microTach molded in this black resin form. I hand formed the shape, and created a silicon mold. I will be molding each part personally. The devices will have wires exiting out the bottom. If you are mounting in an alternative method and need the wires out the top, please let me know. I am also working with a machinist to get polished stainless steel covers made. These can be bonded to this unit using an adhesive such as what is used for grips, or super glue.

I will be leaving the face as-is "grey". I used spray on tint which looks good, but I am concerned about pealing and durability. Therefore, I will leave it up to you to "customize" the front. Feel free to email me with questions about it.

Order entry should be open within a couple weeks.

Problems with the molding company may cause some additional delays.

I am currently exploring 3 types of packaging.

1. Stainless steel shell with epoxy encapsulation: This will be a polished/paintable surface which I hope will enable a chrome-like appearance or black.

2. Black molded resin or epoxy: This is a light weight rugged solution that could be made easily and adapted to many different form factors. This could also be used as a basis and add the stainless steel shell on top.

3. Silver or aluminum bonded resin/epoxy: May provide chrome like finish with flexibility of low cost molding. This enables more variety in form factors and placement options.

Additionally, I am investigating a spray-on tint which give a darker appearance when not lit, yet still allows the LED display to show through. This has a better appearance than the light grey face of the LED display comes with. Although with chrome the grey might look better.
2/25/07 : Molded parts are back! However, I am not quite satisfied with the quality of appearance. Also, there was only 1 out of 4 that had a flush LED display in the mold. I am working with the molding company to rectify the issues. Also, I am talking to a machinist to get casings made. So final product may be delayed. In the mean time I have posted the Installation instructions on the product page. Feel free to review them, and ask questions or comment as needed. Thanks for your continue support.

Injection Molding

Well, the tooling for the mold is in development. The guys at TEMS are expediting as best they can. Hopefully, I will have some mechanical drawings next week. And if things go according to plan, some prototype molded parts by mid-February. And soon after product to sell. I have looked into the payment options and Paypal seems the easiest to get going and cost is lower as well.
