Problems with Honda Rancher 420 (With Solution):

Honda Rancher 420 is equipped with the latest technology and features. Moreover, it is a particular form of ATV that is durable and balanced.

Still, the Honda Rancher 420 has reported several problems, and owners have claimed about the issues which I discuss below:

1. Issues with the Shifter:

Honda Rancher 420 has shown the issue of being stuck due to the shift lever. When the shift lever malfunctions, the neutral indicatior flashes twice, and there is a brake light.

When the brake light is turned on, the twice-blinking neutral indicator acts as an error code for the electronic shift system. Conversely, if all the brake light switches are turned off on the brake lever, the light does not function well, and in such a scenario, the high beam performs better.

How to Fix?

The issue with the shifter in Honda Rancher 420 can be fixed easily through the following steps:

  • Step 1: Fetch a shifter tool (generally comes with the manual).
  • Step 2: Insert the tool in the over-ridden slot and hold it in its place while pushing it down.
  • Step 3: Depress the brake pedal while attempting to shift the override mechanism.
  • Step 4: Push the button on the shift and hold the shifter.
  • Step 5: After attempting all these steps, you can check the display if there is still no change in the shift lock feature.
  • Step 6: Change the settings of the default camera mode and use the feature of shift lock.

2. Issues with the Carburetor and Fuel:

The issues associated with the carburetor and fuel arise due to the dust and dirt in them, which can be resolved by cleaning them. It is advisable to clean the bowl by floating the valve and injecting the injectors to inspect the holes.

You can use the wire brush to clear and drain the obstructions from the damaged nozzle holes. However, there also arises the need to change the lead screws with compatible ones.

It is a delicate process of removing the old screws and mounting the new ones. It sometimes leads to damage to the carburetor. For example, if you wants to clean the carburetor, they can blow the air through a fuel inlet in the carburetor tubes.

How to Fix?

You can fix the issue with the carburetor and can clean it through the following steps:

  • Step 1: Use a diluted cleaner for washing the carburetor. Mix one part of cleaner in three parts of water in a container to make a dilute mix.
  • Step 2: Clean out the air filter of the carburetor and remove it.
  • Step 3: Remove the float of the carburetor along with other removable components.
  • Step 4: Soak the removable components in the diluted mixture and scrub them thoroughly.
  • Step 5: Rinse and dry away the components of the carburetor and reassemble them again.

Sometimes, dust, debris, and grime stick on the sides and walls of the carburetor. You can vacuum those using a cordless vacuum to remove them away and fix the issue with the carburetor.

You can use old clothes to protect and clean the carburetor’s surfaces. You can apply the choke cleaner in thin coats, settling the grime.

3. Issues with the Steering:

Few Honda Rancher 420 owners have reported the issue of tight steering. The steering shows such problems when Rancher is driven for about 5-10 miles per hour.

In such a situation, the vehicle accelerates quickly toward the desired direction that tightens the steering wheel.

It is recommended to tweak the tie rods, which helps lessen the tenseness created in the steering. You can examine the ball joints if they are in excessively tight condition.

You can detach the tie rods from the knuckles if there is an issue with the ball joints. It is also advisable to apply grease and oil to loosen the stiffness.

Engine blubbing is common when Honda Rancher 420 is cut off at half throttle. This issue arises due to improperly fitted valve clearances and compressions in the vehicle, which can be fixed by removing the air box. However, it is a short-term fix that can harm the engine and performance of the vehicle.

Airbox removal can cause water entry into the carburetor, damaging the motor during washing. You can replace the spark plug if you want to avoid this issue.

How to Fix?

You can fix the steering issues by following the steps:

  • Step 1: Turn the steering wheel towards the 45 degrees angle from the straight position to the left one.
  • Step 2: Turn the ignition to the ‘ON’ position.
  • Step 3: The EPS light will remain on for a few seconds and switch off.
  • Step 4: After the EPS indicator turns off, turn the steering to straight position.

If this doesn’t solve the issue and the steering gets overloaded, I suggest to follow the video instructions below:

4. Issues with Electronic Shift Program:

The electronic shift program is a widespread transmission that most riders love to use in their vehicle. This shift program ensures easy-time shifting gears. If you are a rider who loves to enjoy sport style, this transmission is the best option for you.

A neutral lockout function engages when you drive at a speed of more than 2 miles per hour. It makes the system of braking easier and handier.

However, sometimes, an issue arises with the electronic shift program and vehicle motor, due to which the Rancher 420 does not shift the gears.

There are various reasons behind the problem with electronic shift programs, including:

  • A wet motor due to the sudden submerging of the vehicle in the water
  •  Burning out of the motor due to hooking up with the battery
  •  Inadequate charging of the battery
  •  Grease in the shift motor gears

For diagnosing and changing the shift motor, follow the video instructions below:

If the battery is not adequately charged, make sure to charge it, which can fix this issue properly. If there is too much grease in the vehicle, you can replace it with all-temperature white lithium grease.
