- You should also listen for the fuel pump to cycle when you turn on the ignition. If you don’t hear it, or if it sounds abnormal, there may be a problem with the fuel pump or the fuel filter.
- Clean or replace your fuel pump and filter as needed to restore proper fuel flow to your engine, inspecting and maintaining these components per the Indian-suggested service intervals.
2. Indian Roadmaster Wont Shift
Shifting gears is an essential skill for any motorcycle rider, but sometimes your bike may not cooperate. If your Indian Roadmaster is having trouble shifting, it could be due to a misadjusted clutch, a faulty circuit breaker, or a bad gear switch sensor.
Adjust your Clutch Cable and Lever
The clutch is the device that allows you to change gears smoothly, and if it is not adjusted correctly, it can cause shifting problems.
- Examine your clutch cable for any signs of wear or damage and replace it if necessary.
- You should also adjust your clutch lever to have about 1/8 inch (3 mm) of free play at the end.
- Ensure that your clutch is fully disengaged when you pull the lever and fully engaged when you release it.
Troubleshoot your Gear Switch Sensor
The gear switch sensor is the device that tells your Roadmaster’s computer what gear you are in and displays it on your LCD screen and RIDE COMMAND display. If it is malfunctioning, it can cause your bike not to shift correctly or show incorrect gear readings.
- You can check the gear switch sensor by using a multimeter to measure the resistance between its terminals and compare it to the specifications in your service manual.
- If the sensor is out of its ideal Ohms range, you may need to replace it.
3. Indian Roadmaster Cutting Out
If your Indian Roadmaster is cutting out while riding, it could be due to a rear cylinder deactivation feature, a clogged fuel system, or a restricted exhaust system.
Disable Rear Cylinder Deactivation
Rear cylinder deactivation is a feature that shuts off the rear cylinder of your bike when it is hot and idle to reduce engine and exhaust heat to the rider.
However, some owners have reported that this feature can cause their bikes to cut out while riding after running rough in certain conditions.
You can turn off rear cylinder deactivation by accessing the settings menu on your RIDE COMMAND display.
- In some cases, the rear cylinder is turned on for legitimate reasons and just fails to automatically turn itself off once the bike’s engine cools down.
- In other cases, the Roadmaster’s temperature sensor may be contaminated or have loose wiring and is relaying improper data to the ECU, causing it to deactivate your rear cylinder even at safe operating temps.
- Finally, it may be that your ECU needs an update from the dealership and is misinterpreting data from your bike’s sensors.
Check your Fuel System
Your Roadmaster needs fuel to run, and if there is something wrong with your fuel system, your bike may cut out, either while riding or at start-up.
- Examine your fuel level and make sure you have enough gas in your tank.
