Why the 2008 Outlander 650 is Still a Trail Legend
Before we dive into the nuts and bolts, let’s appreciate what makes this machine special. The benefits of a can am outlander 650 2008 are still incredibly relevant today. It was a game-changer when it launched and remains a formidable presence.
At its core is the 650cc Rotax V-twin engine. This isn’t just any motor; it’s known for its incredible low-end torque and a sound that just screams performance. It’s perfect for crawling over rocks or blasting through muddy ruts.
Can-Am paired that engine with some brilliant chassis technology. The TTI (Torsional Trailing arm Independent) rear suspension allows the wheels to move vertically, not in a butterfly motion like competitors. This keeps the tires planted for better traction and a smoother ride.
Up front, the Visco-Lok auto-locking front differential was revolutionary. It sends power to the wheel with grip, pulling you through situations where other ATVs would be spinning their tires. It’s a simple, effective system that just works.
Common Problems with the Can-Am Outlander 650 2008 and How to Fix Them
Every great machine has its Achilles’ heel. Knowing the common problems with a can am outlander 650 2008 is half the battle. Here’s what to watch for and how to tackle it like a pro.
Overheating Issues and Cooling System Care
That powerful V-twin generates a lot of heat. If your temperature light is flashing, don’t panic. Start with the most common culprit: a mud-caked radiator.
Pro Tip: Don’t just spray the front of the radiator. Most of the mud gets packed in from the back, thrown by the tires. Use a garden hose (never a pressure washer, which can bend the delicate fins) and spray from the fan-side out.
If it’s still running hot, check your cooling fan. Turn the key on (engine off) and see if the fan kicks in as it warms up. If not, check the fan’s fuse and relay in the fuse box. A faulty coolant temperature sensor can also prevent the fan from turning on.
Electrical Gremlins: Stator and Voltage Regulator Woes
Is your battery always dying, or are your lights dim at idle? The charging system, specifically the stator and voltage regulator, is a known weak point on these models.
To diagnose, you’ll need a decent multimeter. With the engine running at around 3000 RPM, test the voltage across your battery terminals. You should see between 13.5 and 14.5 volts. If it’s below 13V, your system isn’t charging. If it’s over 15V, your regulator is likely fried and is overcharging the battery.
Testing the stator involves checking the resistance (Ohms) and AC voltage output from the three yellow wires coming from the engine case. Consult a service manual for the exact specs, but if you’re not comfortable with electrical diagnostics, this is one job best left to a trusted shop.
Drivetrain and Differential Checks
Your differentials and gearbox work hard. Don’t neglect their fluids. We recommend changing the front diff, rear diff, and gearbox oil at least once a season, or more if you ride in deep water.
Use a quality 75W-90 synthetic gear oil for the front and rear differentials. The gearbox requires the same oil as your engine. While you’re under there, carefully inspect the rubber CV boots on all four axles. A tiny tear can let in dirt and water, destroying the joint inside. A new boot is cheap; a new axle is not.
Your Essential Can-Am Outlander 650 2008 Care Guide & Maintenance Schedule
Following a solid maintenance plan is the key to longevity. This can am outlander 650 2008 care guide simplifies what you need to do to keep your machine trail-ready and reliable, following best practices.
Pre-Ride Inspection: The 5-Minute Lifesaver
Before every single ride, take five minutes to perform this check. It can save you from a long walk back to the truck.
- Tires & Wheels: Check air pressure. Look for any cuts or embedded objects. Grab each tire and check for loose wheel bearings or tie rods.
- Fluids: Check your engine oil level and coolant level in the overflow bottle. Give a quick glance under the machine for any new drips.
- Controls & Brakes: Squeeze the brake levers to ensure they feel firm. Check the throttle for smooth operation and make sure it snaps back cleanly.
- Lights & Electrical: Turn the key on and check your headlights (high and low beam), taillights, and brake lights.
- Chassis: Do a quick visual scan. Look for any loose bolts, cracked welds, or damaged parts on the frame and suspension.
Routine Maintenance You Can Do at Home
This is the core of your how to can am outlander 650 2008 maintenance plan. Get these done, and you’ll prevent most major issues.
Engine Oil & Filter Change:
- Warm the engine for a few minutes to get the oil flowing.
- Place a drain pan under the engine and remove the drain plug. Be careful, the oil will be hot.
- Remove the oil filter cover (usually three small bolts) and replace the old filter with a new one. We recommend a HiFlo HF152 or equivalent.
- Reinstall the drain plug (with a new crush washer!) and filter cover. Torque to spec.
- Refill with approximately 2.1 quarts of a quality 5W-40 synthetic blend oil rated for wet clutches. Check the dipstick to confirm the level.
Air Filter Service:
Your air filter is the only thing protecting your engine from dust and dirt. After every dusty ride, pop the seat off and inspect it. If it’s a reusable foam filter, clean it with filter cleaner and re-oil it. If it’s a paper filter, tap it out gently or replace it if it’s clogged.
How to Get More Performance from Your Outlander 650
Ready to take your Outlander to the next level? These modifications provide the best bang for your buck without sacrificing reliability.
Clutching for Power and Reliability
If you’ve added bigger, heavier tires, your stock clutching is no longer optimized. The engine has to work harder to turn them, leading to belt slip and sluggish performance.
A quality clutch kit from a brand like Dalton or EPI includes new springs and weights for your primary and secondary clutches. It recalibrates the system to keep the engine in its powerband, resulting in snappier acceleration and better belt life. It’s arguably the single best performance mod you can do.
Tires and Wheels: The Foundation of Off-Road Capability
The right tires can completely transform how your machine handles. For general trail riding, a 6-ply all-terrain tire like the Maxxis Bighorn 2.0 is a fantastic choice. If you’re a mud fanatic, look at more aggressive options like the ITP Mud Lite II.
Just remember, going up in tire size adds rotational mass and stress on your drivetrain. If you go larger than 27 inches, a clutch kit becomes less of an option and more of a necessity.
Sustainable and Eco-Friendly Riding Practices
Being a responsible off-roader means protecting the trails we love. Adopting a few sustainable can am outlander 650 2008 habits ensures these areas stay open for everyone.
When performing maintenance, always have a plan for your used fluids. Most auto parts stores accept used engine oil for free. Never dump oil or coolant on the ground or down a drain.
Look for eco-friendly can am outlander 650 2008 products, like biodegradable cleaners and chain lubes. These products work just as well but have less impact on the environment if they drip or wash off on the trail.
Finally, always practice Tread Lightly! principles. Stay on marked trails, cross streams only at designated crossings, and pack out everything you pack in. The goal is to leave the trail better than you found it.
Frequently Asked Questions About the Can-Am Outlander 650 2008
What type of oil is best for a 2008 Outlander 650?
The best choice is a 5W-40 synthetic or synthetic-blend motorcycle/ATV oil that is rated JASO MA for wet clutches. BRP’s XPS oil is the factory recommendation, but high-quality alternatives from brands like Mobil 1, Amsoil, or Rotella T6 also work great.
How often should I change the differential fluid?
A good rule of thumb is to change the front and rear differential fluid at least once per year or every 100 hours of use. If you frequently ride in deep water or mud, you should check it after every ride and change it immediately if it appears milky or contaminated.
My Outlander 650 is hard to start. What should I check first?
Start with the basics. Ensure you have a fully charged, healthy battery; these V-twins require a lot of cranking amps. Next, check your spark plugs for fouling. If those are good, inspect the fuel system—make sure the fuel pump is priming when you turn the key on.
What is the top speed of a stock 2008 Can-Am Outlander 650?
A stock Can-Am Outlander 650 from 2008 can typically reach a top speed of around 65-70 mph (105-113 km/h) on a flat surface, depending on rider weight and conditions. Its real strength, however, is its acceleration and low-end torque, not its top-end speed.
The can am outlander 650 2008 is a truly special machine. It’s a bridge between old-school raw power and modern ATV technology. With this guide and a little bit of wrench time, you can easily address its known issues and keep it delivering thrilling rides for many years to come.
