2005 Honda Rincon 650 Problems (9 Common Problems)

In this article, we will discuss some of the most common problems that owners of the 2005 Rincon 650 have faced and provide solutions. 

2005 Honda Rincon 650 Problems

2005 Honda Rincon 650 Problems

1. Overheating Issue

The 2005 Honda Rincon 650 ATV can suffer from an overheating issue due to the radiator or cooling fan not functioning correctly. 

This can cause the engine to overheat and become damaged. 

To prevent this problem, it is important to regularly check the radiator and cooling fan for any blockages or faulty parts that may prevent them from working properly. 

Additionally, if your ATV is often ridden in hot temperatures, make sure to take regular breaks to help the engine cool down if it begins to overheat.

2. Engine Noice

Engine noise is a common problem with the Honda Rincon 650. 

It is generally caused by faulty or worn-out components, including spark plugs, bearings, oil seals, valves, and piston rings. 

In some cases, it can even be caused by dirt and debris clogging up the engine parts.

The most effective way to address engine noise issues is to conduct a thorough maintenance check of all engine components. 

This includes checking the spark plugs for corrosion or damage; lubricating any moving parts; inspecting the fuel lines and air filter for signs of blockage; replacing any worn out or damaged parts such as gaskets, pistons rings, or valve guides; checking the ignition system and timing chain for accuracy; and cleaning any excess carbon deposits from moving parts.

3. Difficulty steering

The 2005 Honda Rincon 650 can suffer from difficulty steering due to a few potential causes. 

If the steering is difficult, it may be due to worn or loose components in the steering assembly, an issue with the front suspension, or improper tire pressure. 

To diagnose the issue further, check the wheel bearings and tie rods for wear and tear. 

Check that all screws and bolts are properly tightened and that all nuts and bushings are in good condition. 

Inspect the front-end suspension components such as shock absorbers, struts, ball joints, etc., for any damage or signs of excessive wear.

4. Vibrations at High Speeds

Vibrations at high speeds can be frequent in the 2005 Honda Rincon 650. 

This is usually due to a faulty or damaged engine, drivetrain, or other component. 

The most common causes are a misaligned drive belt, worn out or not properly tensioned spark plugs, and/or loose engine mounts.

In order to fix these issues, it is important to inspect all of these components and replace any that may be damaged. 

Additionally, ensure that all components are securely mounted and tightened properly. 

It is also recommended to check for any obstructions around the engine compartment, such as debris or dirt buildup, which can lead to vibrations when running at high speeds.

5. Poor engine performance

Poor engine performance can be caused by several potential causes, such as a faulty spark plug, worn-out carburetor, or clogged air filter. 

A spark plug that is too weak or misfiring can cause the engine to run less efficiently, resulting in lower fuel economy and slower acceleration. 

Worn-out carburetors can cause the engine to run inconsistently and may cause it to stall at low RPMs. 

A clogged air filter can reduce airflow to the engine, causing it to not receive enough oxygen for combustion.

To diagnose poor engine performance, a mechanic will typically perform a visual inspection of all components related to the engine. 

This includes checking the spark plug for signs of wear and inspecting the carburetor for any deposits or corrosion that may be affecting its operation. 

The air filter should also be checked for dirt or debris that could block proper airflow. 

After any problems are identified and addressed, engines should then be re-tested for performance issues, and tuning done as necessary.

6. Poor fuel economy

Poor fuel economy is one of the most common problems reported by owners of the 2005 Honda Rincon 650. 

This issue is generally caused by a combination of factors, including insufficient maintenance, dirty or clogged air filters, incorrect spark plug gap settings, improper fuel-air mixture settings, and low-quality fuel. 

To fix this problem, it is recommended that owners check and clean their air filters regularly; adjust the spark plug gap and fuel-air mixture according to manufacturer specifications; and use only premium-grade gasoline with a minimum octane level of 91.

7. Dirty Carburetor

Dirty carburetors can cause a number of problems with your 2005 Honda Rincon 650, ranging from decreased overall performance to engine stalling and unreliable starting. 

When dirt and other debris build up in the carburetor, it can clog or restrict air flow, leading to an incorrect fuel-to-air mixture which will affect your engine’s operation. 

In some cases, dirt buildup can even lead to complete blockage and prevent the engine from running at all.

To avoid this issue, it is important to regularly clean out your Rincon’s carburetor using either compressed air or a specialized carburetor cleaning solution. 

If you do not feel comfortable doing this yourself, you should take your vehicle to a qualified mechanic who can diagnose and perform the required maintenance. 

Additionally, you may want to consider investing in a fuel filter that prevents dirt and other particles from entering your carburetor in the first place.

8. Starting Issue

Starting an ATV can be a tricky endeavor, and the Honda Rincon 650 is no exception. 

This model of all-terrain vehicle is known to have difficulties when starting, which can range from problems with the battery to the starter motor itself. 

One of the most common issues is that the battery may become drained after extended periods of inactivity, meaning you will need to either recharge it or replace it entirely. 

Additionally, there may be an issue with the starter motor’s engagement solenoid or its electrical connections. 

It is also possible that dirty spark plugs, worn-out drive belts, or even a lack of oil could be causing these starting troubles. 

If you are having trouble getting your Honda Rincon 650 started, it is important to investigate each component thoroughly and address any issues quickly before further damage occurs.

9. Shifting Problems

Shifting problems with the 2005 Honda Rincon 650 can manifest through a variety of symptoms. 

If you experience jerky, rough, or excessively long shifting, this could be a symptom of transmission issues. 

You may also notice that your bike is having difficulty finding the right gear when accelerating from a stop, or that it suddenly lurches forward when you try to shift into neutral. 

If your bike has been running for an extended period at higher RPMs and suddenly shifts hard into lower gears, this could be related to overheating of the transmission fluid.


The Honda Rincon 650 is a great all-terrain vehicle that can handle just about any terrain. 

However, it does have some common problems that you should be aware of before making your purchase. 

Knowing what kind of potential issues could arise with this ATV will help you make an informed decision when purchasing one for yourself or others.
