In this complete 2009 can am outlander 800 guide, we’ll dive deep into essential maintenance, troubleshoot the most common problems you’ll face, and explore smart upgrades that make a real difference. Let’s get that Outlander running better than ever.
Why the 2009 Can-Am Outlander 800 is a Modern Classic
Before we grab the tools, it’s worth appreciating what makes this machine so special. It wasn’t just another quad; it was a game-changer that set a new standard for performance and comfort in the ATV world. Understanding its strengths helps you appreciate why it’s worth maintaining.
The biggest of the benefits of 2009 can am outlander 800 is its heart: the 71-horsepower, 800cc Rotax V-twin engine. This powerplant delivers incredible torque and a top end that will still plaster a grin on your face. It’s a motor that loves to be pushed.
Paired with that engine is Can-Am’s innovative TTI (Torsional Trailing arm Independent) rear suspension. This design allows the wheels to move vertically, minimizing camber changes and keeping the tires planted for better traction and a surprisingly smooth ride over rough terrain.
This combination of raw power and a sophisticated chassis makes the Outlander 800 incredibly versatile. It’s just as capable hauling gear around the farm as it is conquering black-diamond trails.
Your Essential 2009 Can-Am Outlander 800 Care Guide
Proactive maintenance is the cheapest insurance you can buy for your ATV. A little time in the garage saves you a lot of headaches (and money) on the trail. This is our checklist of non-negotiable best practices.
Pre-Ride Inspection: The 5-Minute Lifesaver
Never, ever skip this. It takes five minutes and can prevent a catastrophic failure or a long walk home. We use a version of the motorcycle T-CLOCS checklist.
- Tires & Wheels: Check for proper air pressure (usually 5-7 PSI, check your sidewall). Look for cuts or punctures. Grab each wheel and check for wobbly bearings.
- Controls & Cables: Test your throttle for a smooth return. Squeeze the brake levers—they should feel firm, not spongy. Check cable integrity.
- Lights & Electrics: Turn the key on. Test your headlights (high and low beams), taillights, and brake lights.
- Oil & Fluids: Check your engine oil level. Glance at the coolant overflow bottle. Look under the machine for any new drips or leaks.
- Chassis & Suspension: Look over the frame for any cracks, especially around welds. Check your CV boots for tears. Push down on the machine to test suspension action.
Engine Oil & Filter: The Heartbeat of Your Rotax
The Rotax V-twin works hard, and clean oil is its lifeblood. Don’t cheap out here. Change the oil and filter every 50 hours or at least once a season, whichever comes first.
You’ll need a good quality 5W-40 synthetic ATV/motorcycle oil and a compatible oil filter (like a K&N KN-152 or HiFlo HF152). The job is straightforward: warm the engine, remove the drain plug, let it drain completely, replace the filter, reinstall the plug (with a new crush washer!), and refill with the correct amount of oil. Always double-check the level on the dipstick.
Air Filter Maintenance: Breathe Easy on the Trail
Your air filter is the only thing stopping dust and dirt from getting inside your engine. A clogged filter robs power and efficiency. After every dusty ride, pull the filter out and inspect it.
If it’s a foam filter, you can wash it with filter cleaner, let it dry completely, and then re-oil it with proper foam filter oil. If it’s a paper filter, tap the loose dust out. If it’s caked in dirt, just replace it. It’s a cheap part that protects a very expensive engine.
Tackling Common Problems with the 2009 Can-Am Outlander 800
Even the best machines have their quirks. Knowing the common problems with 2009 can am outlander 800 models helps you diagnose issues quickly and confidently. Here’s how to tackle the usual suspects.
Overheating Issues: Keeping Your Cool
If your temp light is flashing, the first place to look is the radiator. It’s a magnet for mud and debris. Do not use a pressure washer, as it can bend the delicate cooling fins. Use a garden hose and a soft brush to clean it from the back side, pushing debris out the way it came in.
If it’s clean and still overheating, check that the radiator fan is kicking on. If it isn’t, you could have a blown fuse, a bad relay, or a faulty fan motor. Also, ensure your coolant level is correct in the overflow bottle.
Electrical Gremlins: Chasing Wires
Can-Ams from this era are known for occasional electrical issues, often stemming from the charging system. If you have a dead battery or flickering lights, the two main culprits are the stator and the voltage regulator/rectifier.
You can test the stator’s output with a multimeter set to AC volts. If the stator checks out, the regulator is the next logical suspect. Always ensure your battery terminals are clean and tight first—sometimes the simplest fix is the right one.
CV Boot & Axle Wear
The rubber boots protecting your Constant Velocity (CV) joints are vulnerable to sticks and rocks. A torn boot lets grease out and dirt in, which quickly destroys the joint. Inspect your boots regularly. If you see a tear, replace it immediately with a CV boot kit.
If you hear a loud clicking or popping sound when turning, it’s likely a sign that a CV joint is already toast. Replacing the entire axle is often easier and more cost-effective than rebuilding the joint itself.
Smart Upgrades: Performance & Reliability Mods
Stock is good, but custom is better. These are some of the most effective upgrades that provide real benefits on the trail. This section covers some advanced how to 2009 can am outlander 800 modifications.
Tires & Wheels: The Foundation of Your Ride
The single best upgrade you can make is a good set of tires matched to your terrain. The stock tires are a compromise. Moving to a more aggressive 6-ply or 8-ply tire like the Maxxis Bighorn 2.0 or ITP Mud Lite will drastically improve traction and puncture resistance.
Clutching for Performance
If you’ve added larger, heavier tires, your stock clutch will struggle. A clutch kit comes with different springs and weights to recalibrate your CVT system. This helps restore lost low-end power, improves acceleration, and reduces belt slippage, which saves your drive belt from premature wear.
Skid Plates & Protection
The underside of your Outlander is exposed to everything the trail can throw at it. A set of full-belly skid plates, made from either high-impact plastic (UHMW) or aluminum, is essential. They protect your engine case, frame, and differential from rocks and stumps that could end your day.
Sustainable & Eco-Friendly Riding Practices
Being a true off-roader means respecting the environment we play in. Following a few sustainable 2009 can am outlander 800 best practices ensures our trails stay open for generations to come.
Proper Fluid Disposal
When you change your oil or coolant, never dump it on the ground or down a drain. Used oil is a hazardous material. Pour it into a sealed container and take it to your local auto parts store or municipal recycling center. Most places will take it for free.
Treading Lightly on the Trail
The core of being an eco-friendly 2009 can am outlander 800 rider is minimizing your impact. Stay on designated trails, avoid creating new bypasses around obstacles, and cross streams only at designated crossings. Avoid spinning your tires excessively, as this accelerates trail erosion.
Efficient Maintenance for a Cleaner Ride
A well-maintained machine is a more efficient machine. A clean air filter, correct tire pressure, and a properly tuned engine all contribute to better fuel economy and fewer emissions. Regular maintenance isn’t just good for your ATV; it’s good for the environment.
