The Bombardier Quest 650, a rugged all-terrain vehicle (ATV) designed for both recreation and work, boasts a powerful engine, superior suspension, and commendable load-carrying capacity.
But like all vehicles, the Quest 650 is not without its problems.
In this article, we will take a look at the common problems of Bombardier Quest 650 along with their possible solutions.
Bombardier Quest 650 Problems
1. Overheating Problem
Overheating in a Bombardier Quest 650 is typically caused by an engine not receiving enough air or a clogged radiator.
The most common symptom of overheating is the appearance of white smoke coming from the exhaust pipe or from underneath the hood.
If left unchecked, this can cause damage to the pistons and other engine components, as well as reduce performance.
To prevent overheating, make sure your air filter is clean and there are no blockages in either the intake or exhaust systems.
Also, inspect your radiator for any signs of corrosion or buildup of debris that may be blocking airflow around the cooling fins.
Finally, check all hoses and pipes for proper connection to ensure the coolant is flowing properly throughout the system.
2. Braking Problems
Braking problems with the Bombardier Quest 650 can be caused by a variety of things, including a lack of fluid in the brake system, the air in the system, an old or worn-out set of brake pads, or an issue with the master cylinder.
Brake fluid is essential to proper braking function; if it is low or empty, there will be no stopping power.
Air in the system can cause inadequate pressure and result in reduced braking performance.
Worn-out brake pads can cause grinding noises when applying the brakes and make them feel spongy when used.
Concerns with the master cylinder could include a leaking component or a defective piston which could lead to insufficient pressure being applied to the brakes.
To fix these issues, it’s important to have a qualified mechanic inspect and diagnose any problems as soon as possible to ensure safety and reliability while driving.
3. Start Issue
The Bombardier Quest 650 is a popular light sport aircraft. Unfortunately, it is not without its problems.
One of the most common issues with the Quest 650 is a weak battery, which can be caused by battery wear and tear over time.
This can lead to engine starting problems or even complete power loss while in flight.
To help reduce these problems, it is important to keep the battery charged and in good condition by regularly checking its voltage and replacing it when necessary.
Additionally, it may be necessary to have the electrical system checked for faults, as this could also cause weakened battery performance.
4. Poor acceleration
Poor acceleration in a Bombardier Quest 650 can be caused by several factors, such as dirty air filters, low fuel pressure, or blocked fuel lines.
Other potential causes include faulty spark plugs, worn-out ignition coils, or dirty injectors. All of these issues can impede the engine’s ability to generate sufficient power.
The best way to identify the source of poor acceleration is to have the plane inspected by a certified technician.
The mechanic should be able to diagnose any underlying problems and suggest suitable solutions.
In some cases, simply replacing dirty air filters and spark plugs may be enough to restore normal acceleration levels.
For more serious problems such as fuel pressure issues or blocked fuel lines, more intensive repairs may be needed.
5. Running Problem
Running problems with the Bombardier Quest 650 may be caused by incorrect or insufficient fuel and oil, a spark plug not firing correctly, or a clogged air filter.
The fuel and oil should be checked periodically to ensure that they are at the correct levels.
If the spark plug is not firing correctly, it should be replaced immediately as it can cause damage to the engine if left unchecked.
The air filter should also be cleaned periodically to prevent any blockage from affecting the engine’s performance.
6. Fuel efficiency
Fuel efficiency is a serious issue for many Bombardier Quest 650 owners. In some cases, the fuel tank may be larger than it needs to be for the aircraft, leading to increased fuel consumption and reduced range.
Additionally, improper maintenance and/or air filter clogs can lead to less efficient burning of fuel in the engine.
To maximize fuel efficiency, it’s important to keep the Quest 650 maintained regularly, including changing the oil and air filters regularly.
Additionally, ensure that any necessary repairs are completed as soon as possible to prevent unnecessary wear on the engine or other components.
Finally, when selecting a fuel tank size or configuration, consider how much fuel will actually be necessary for the flights planned so that unnecessary weight isn’t carried around in the form of extra fuel.
7. Poor handling
Poor handling of the Bombardier Quest 650 is often caused by an incorrect center of gravity or, more commonly, an incorrect weight distribution.
As the Quest 650 is designed to carry a fairly heavy load, it is important to ensure that the cargo is evenly distributed and that the center of gravity is in the right position.
Incorrect weight distribution can cause instability during handling and lead to poor maneuverability, making it difficult for pilots to make tight turns or difficult maneuvers. If left uncorrected, this can result in dangerous situations.
To rectify this problem, the pilot should check both the aircraft’s weight and its center of gravity before takeoff.
This should be done using a measuring device such as a load cell or a scale as well as a bubble level or inclinometer.
To achieve optimal performance, it is important that both readings are correct before taking off.
8. Difficult maintenance
Difficult maintenance on the Bombardier Quest 650 can be a major issue for owners.
Due to its aging design, many of the components have become obsolete and practically impossible to find.
Additionally, due to its complicated hydraulic system, it can be incredibly difficult to diagnose and repair any issues that may arise during use.
Furthermore, the parts that are still available are often very expensive and hard to source which can lead to long repair times or costly replacements.
Conclusion
The Bombardier Quest 650 is an incredibly powerful and capable off-road vehicle.
However, it can be prone to certain issues that can affect its performance if not addressed in time.
This article discussed the most common problems associated with the Bombardier Quest 650, as well as ways you can prevent them from occurring or fix them when they do happen.

I’m Harvey, and I know everything there is to know about offroad vehicles. I’ve been driving them since I was a kid, and I love nothing more than exploring the great outdoors in my Jeep, ATV or UTV. I grew up in a small town in Idaho, and that’s where my love for offroad vehicles started. There were no paved roads where I lived, so we had to drive on dirt trails to get around. And that’s when I fell in love with the thrill of being able to go anywhere I wanted, no matter how rough the terrain was. LinkedIn | Instagram
