HD Combination Speedo/Tach

1)

HD 70900274

This 4“ Combination Digital Speedometer and Analog Sweep Tachometer is offered as an upgrade item and allows you to monitor engine speed, fuel level and gear position, without adding additional handlebar-mounted gauges. See Fitment Info below.

  • 4” Spun Aluminum Dial, MPH/km/h, Worldwide Models
  • Unit mounts in the stock dash opening and is a direct plug-in installation
  • Backlit gauge includes a large LCD (liquid crystal display) information screen that displays odometer/tripmeter data, miles-to-empty readings, an easy-to-read segmented fuel display, a gear position indicator and clock
  • Features push-button adjustable backlighting with over 600 color tone options allowing the rider to adjust pointer, LCD and backlighting colors to match any paint scheme or viewing preference
  • Digital speed reading can be easily toggled between MPH and kph to simplify cross-border travel
  • Mileage reinstatement resides in the vehicle ECM so initial mileage will be uploaded at the time of installation
  • 07+ Sportsters require additional Fuel Sensor Kit (HD 61200008) to utilize Fuel Gauge and Range function

Fitment: Fits '04-'13 XL (except XR, XL50 and '04-'08 XL1200R)
Note: As a result of different vehicle capabilities, the following exceptions apply: Gear position not available on ’04-’07 models, Range function not available on ’04-’06 XL models and ’04-’08 Dyna® models, Fuel level function not available on ’04-’06 XL models.


HD 70900475

This 4“ Combination Digital Speedometer and Analog Sweep Tachometer allows you to monitor engine speed, fuel level and gear position, without adding additional handlebar-mounted gauges. See Fitment Info below.

Features are as listed above for pre-2014 models.

Fitment: Fits '14-later XL US models. XL models require separate purchase of Fuel Sensor Kit P/N 61200008A to make use of the fuel level and range function.



HD 61200008A XL Fuel Level Sensor Kit

This kit has a graduated, in-tank sensor unit which is based on capacitive sensing technology to accurately monitor the fuel level. Included is a jumper plug to replace the stock resistor pack and a new fuel pump gasket. Specified to be compatible with 70900100C, 70900274 and 70900475, it has been discovered that it is also able to activate the fuel level gauge on the 2016-later 1200CX Roadster speedometer, P/N 70900549. 2)

The in-tank sensor provides the fuel level information to the Speedo/Tach LCD display for at-a-glance viewing.

The sensor produced multiple levels of resistance based on the fuel level, thus elimnating the previous two-level (ok/lo) resistor pack function. The jumper plug shorts socket1 to socket2 of connector 200B, thus grounding the new in-tank sensor. Socket3 of connector 200B is not used and simply plugged.

Note: There have been many reports that it is difficult to make the jumper plug contact pins protrude enough to make contact with the sockets in the 200B connector. Be sure you assemble the jumper correctly and insert the pins sufficiently.

HD Sportster Fuel Gauge Kit

75031-09 - Sportster Fuel Gauge Kit - Black
75338-09 - Sportster Fuel Gauge Kit - Chrome

This kit fits '07-later XL and replaces the master cylinder cover on the right hand controls. It provides four levels of fuel from FULL to LOW, with the bars going dark. The lowest indicator will be lit near the same time as the Speedometer low-fuel indicator. When the sensor cannot detect a fuel level, the lowest indicator will begin to flash. Note that the Fuel Pump Icon will remain lit whenever power is on and is not part of the level indication. During the installation of the gauge, the Fuel Sender Resistor Assy is removed and the gauge wiring is plugged into Connector 200B instead of the Resistor Assy.

This kit uses fuel gauge sensor 75093-09, which uses capacitive-sensing technology to detect the fuel level.

For 2007 models (only) - After the sensor is installed & connected to the gauge, the motorcyle must be taken to a dealer to have a software update installed by the dealer's DTII programming before the gauge will operate properly. The low-fuel light will stay on until the update is installed.

If this kit is used with 2014-later models, wire kit 72673-11 is required.


VSS - Modification for 1995-2003 12v Sensor

There have been a lot of issues and malfunctions of speedometers in these years. The below modification is intended to raise the voltage under load for the sensor as a possible fix for intermittent malfunctions. ( See this XLForum Thread which is related.)


VSS/Speedometer Pulse Rate Converter

The Vehicle Speed Sensor produces a different number of pulses-per-mph between the 883 and 1200 models. The electronic speedometers on 1995-2003 model Sportsters were different between the 883 models and the 1200 models. Beginning in 2004, the VSS signal was sent to the ECM so that the ECM could be programmed to account for the differences between the models and send the right speed information to the speedometer.

Dakota Digital makes a product (SIM-1) to receive the pulses from the VSS and convert them to the appropriate pulse rate that is expected by the present speedometer. This conversion can help compensate for larger/smaller tires and different final drive ratios (changes in sprockets).
SIM-1 Product Description - Install Instructions

Apparently, S&S also had a conversion product (55-1007) that is no longer available.

Gauge Mods / Relocating


3)

Headlight Eyebrow Mounted Gauges

The Zena Mod

This is a relatively easy mod to raise the height of your instruments (when using taller risers).
Otherwise, the gauges end up being too tall.
The gauges are removed from the handlebar mount and bolted to the headlight eyebrow using deep chrome sockets.
Cost is under #10. Done carefully, it looks like a factory install.

  • Parts required:
    • (2) - chrome 8mm deep sockets (may be able to use other sizes)
    • (4) - stainless steel washers
    • (2) - 3” stainless steel allen bolts,
      (same diameter as stock but longer to fit sockets accordingly. 3“ bolts used below).
  • Note: This mod should work without a hitch on the 883 std and 1200R.
    • In some instances, folks have reported that the spacing between the holes on the gauge mount
      did not line up perfectly with the holes on the eyebrow.
    • Most were able to quickly remedy the problem with a dremel or other comparable tool.
    • The mod will not work on stock 1200/883 Custom models without additional modification.
Relocating gauges 4)

Variation of the Zena Mod

Before. 5)
After. 6)
Removed upper bar clamp bolts
with a 1/4” Allen wrench. 7)
OEM Handlebar spacers (5736). 8)Added blue Loctite to the handlebar bolts. 9)
Re-installed the bolts without speedo bracket. 10)Removed the eyebrow bolts with a 1/2“ socket. 11)Replaced the OEM bolts with 1/4”x3-1/2“ allen head
cap bolts. 12)
1/2” O.D.x1/4“ I.D. sleeves slid over the bolts with washers under the head.
Sleeves go between the eyebrow and the gauge housing. 13)

Other Pics of this Mod

Done on a 2001 1200S.
1/2”x1-3/4“ threaded rod couplers painted them black with 3-1/2” grade 8 bolts. 14)
Done on an 89 883. 15)

Riser Mounted Gauges

The ReddTigger Mod

Speedo Mount for pullback risers.
The biggest frustration is the angle of the stock mount that's used to mount onto the original handlebar clamp.

  • Parts (total of about $20):
    • 2 chrome socket head screws.
    • 2 chrome acorn nuts.
    • 2 chrome washers.
    • 2 chrome cable clamps for 1“ (or whatever size your risers are).
    • 2 small pieces of tubing.
  • Place the tubing in the cable end of the clamp.
  • Attach clamp to riser as shown below.
  • Attach speedo using stock bracket (or any of your choice).
  • Insert socket head screws w/ washers through stock bracket into hose in clamp.
  • Secure with acorn nuts.
    (the white stuff around the riser is some white electrical tape to prevent scratching) 16)
A bungie cord across the bolts holds a water bottle in the middle 17)
Here's what it looks like with a tach added. 18)
