9 Common Can-Am DS 70 Problems And Their Solutions

The Can-Am DS 70 is a youth ATV designed for riders who are just starting to explore the world of off-road riding. While it is known for its reliability, like any vehicle, it may encounter issues from time to time. Here are some common problems associated with the Can-Am DS 70 and potential solutions:

1. Starter Problem

The Can-Am DS 70 may encounter starter issues, commonly manifesting as a failure to crank or start the engine.

This problem could be attributed to a faulty starter motor, a weak or depleted battery, or corroded connections within the starting system.

Additionally, damaged ignition switches or solenoids might contribute to the non-engagement of the starter.

Fix: To address starter problems on the Can-Am DS 70, begin by checking the battery’s charge and terminals for corrosion.

If the battery is in good condition, inspect the starter motor, solenoid, and ignition switch for any visible damage or malfunction.

Clean or replace components as necessary, and ensure all electrical connections are secure.

2. Transmission Problems

Common transmission problems in the Can-Am DS 70 may include difficulty shifting gears, abrupt gear engagement, or a slipping clutch.

The root cause can often be traced to issues with the transmission fluid, such as low levels, contamination, or improper viscosity.

Additionally, worn-out clutch plates, a misadjusted clutch cable, or linkage problems may also contribute to transmission-related issues in this ATV model.

Fix: When addressing transmission problems in the Can-Am DS 70, start by checking the transmission fluid levels and quality.

Replace or top up the fluid as per the manufacturer’s recommendations. Inspect the clutch system for worn-out components, adjusting the clutch cable and linkage as needed.

If the issue persists, consult the Can-Am DS 70 service manual for model-specific troubleshooting steps.

3. Throttle Cable Issues

Throttle cable issues in the Can-Am DS 70 may manifest as a lack of response or inconsistent acceleration when the throttle is engaged.

The primary cause is often wear and tear on the cable, leading to fraying, stretching, or kinks.

Additionally, dirt and debris accumulation can impede the smooth movement of the throttle cable, causing a lag or irregular response in the ATV’s performance.

Signs of a problematic throttle cable may include sticking, excessive play, or difficulty maintaining a constant speed.

Fix: To address throttle cable issues in the Can-Am DS 70, start by visually inspecting the throttle cable for signs of wear, damage, or obstructions.

Use a lubricant specifically designed for throttle cables to ensure smooth movement. Activate the throttle control lever several times to check for any irregularities.

If there’s difficulty replacing the throttle cable or if it shows clear signs of wear, it may need to be replaced.

4.  Speed Problem

Speed-related problems in the Can-Am DS 70 can be attributed to various issues affecting the overall performance of the ATV.

One common cause is improper adjustment of the throttle or carburetor settings, leading to suboptimal fuel and air mixture.

Issues with the CVT (Continuously Variable Transmission) system, such as belt wear or misalignment, may result in reduced speed capabilities.

It’s also crucial to inspect the air filter, as a clogged or dirty filter can restrict airflow and impact engine performance, affecting the ATV’s speed.

Fix: To address speed problems in the Can-Am DS 70, start by checking whether the throttle and carburetor settings are properly adjusted.

Many speed-related issues stem from an imbalance in the fuel and air mixture, impacting the engine’s power output. 

Inspect the CVT system, ensuring the drive belt is in good condition and correctly aligned. Also regularly check and clean the air filter to ensure proper airflow to the engine.

5. Spark Plug Issues

Spark plug issues in the Can-Am DS 70 may lead to starting problems, poor engine performance, or even engine misfires.

A common cause is a fouled spark plug, often resulting from a rich fuel mixture, oil contamination, or prolonged use.

Another issue could be a damaged or improperly gapped spark plug, hindering efficient combustion.

If the spark plug wire is worn or damaged, it may also contribute to a lack of spark, preventing the engine from starting or causing it to run unevenly.

Fix: To address spark plug issues in the Can-Am DS 70, start by inspecting the spark plug for signs of fouling, wear, or damage.

Ensure the spark plug gap is set according to the manufacturer’s specifications. If the spark plug is fouled or damaged, replacement is necessary.

Also, make sure the spark plug wire is in good condition, with no visible wear or damage.

6.  High Idle Problem

In the Can-Am DS 70, a prevalent issue is a high idle, causing the engine to run at an elevated speed, leading to control difficulties during operation.

This problem can be attributed to a malfunction in the idle control system or occasional carburetor issues. 

An improperly adjusted or stuck throttle cable may also contribute to the engine’s failure to return to a lower idle speed.

Fix: To address the high idle problem in the Can-Am DS 70, mechanics should initially inspect the throttle cable for proper adjustment and signs of binding.

It’s crucial to check the idle screw, which may occasionally become hard, impacting its ability to control idle speed. Additionally, ensure there is a spring pushing down on the carburetor’s barrel/slider, allowing for the correct air/fuel adjustment. 

If necessary, thorough cleaning and lubrication of the carburetor, focusing on moving parts, can contribute to resolving the high idle issue effectively.

7. Carburetor Adjustment

The Can-Am DS 70 may encounter performance issues such as starting troubles, uneven idling, or a lack of power, often attributed to incorrect carburetor settings.

Variables like altitude, weather conditions, and the age of the ATV can influence the fuel and air mixture, impacting overall engine performance if not adjusted according to the manufacturer’s specifications for the specific model and year.

Fix: To rectify carburetor adjustment issues in the Can-Am DS 70, mechanics should refer to ATV’s model-specific manual for recommended settings for the main and idle screws.

Adjustments may be necessary based on the ATV’s specific year and condition. Alongside, it’s crucial to look for signs of trouble, such as irregular idling or difficulties starting the engine.

Additionally, cleaning the carburetor is an essential step to ensure optimal performance by eliminating any potential obstructions or deposits affecting the fuel and air mixture.

Careful adjustment of the carburetor settings and routine maintenance contribute to reliable and efficient ATV operation.

8. Battery Issues

One common issue in the Can-Am DS 70 involves a weak battery or loose connections, leading to difficulties in starting the ATV. Over time, batteries can lose charge or fail due to age, lack of maintenance, or infrequent use.

Corrosion on the battery terminals or cables is another factor that may hinder the electrical system’s efficiency, potentially compromising safety and performance.

Fix: To address battery problems in the Can-Am DS 70, start with a simple yet crucial step: regularly check the battery’s charge level and connections. Ensure the battery is correctly installed, and the terminals are free from corrosion.

If there’s corrosion, clean the terminals with a battery terminal cleaner or a mixture of baking soda and water. Repeat this maintenance routine every 30 days to promote the safety and reliability of the ATV’s electrical system.

9. Rattling Noise

A common concern with the Can-Am DS 70 is the occurrence of a rattling noise during operation. This unsettling noise may originate from various sources within the ATV.

One potential issue could be loose components in the crankcase, such as a loose bolt or foreign object.

Another source of rattling may be within the intake or exhaust system, indicating potential problems with the air intake or exhaust components.

Identifying the specific location of the rattling noise is crucial for effective troubleshooting and resolution.

Fix: To address the rattling noise in the Can-Am DS 70, mechanics should conduct a thorough inspection of the ATV. Start by checking for any loose bolts or foreign objects in the crankcase, ensuring all components are securely fastened.

Inspect the intake and exhaust systems for signs of damage or loose parts. Drain the crankcase oil to inspect for any metal particles that might indicate internal engine issues.

Make sure all components, including the exhaust and intake parts, are properly secured.
