Is your Can-Am Outlander starting to sound more like a sewing machine than a trail-taming beast? That familiar “ticking” sound from the engine, a slight hesitation off the line, or just a feeling that it’s lost some of its punch—these are signs your rig is trying to tell you something.
You’re not alone. It’s a common issue that many riders notice over time. But here’s the good news: you can fix it. We promise that learning the proper can am outlander valve adjustment procedure is one of the most rewarding maintenance tasks you can perform.
This guide will give you the confidence to tackle this job yourself. We’ll break down everything from the warning signs and essential tools to a detailed, step-by-step process that will restore your engine’s performance, quiet that annoying tick, and ensure its long-term health. Let’s get those wrenches turning.
Why Bother? The Top Benefits of a Can-Am Outlander Valve Adjustment
Skipping a valve adjustment might seem harmless, but you’re leaving performance and reliability on the table. This isn’t just about silencing a noise; it’s a critical part of engine health. This is one of the most important aspects of any good can am outlander valve adjustment care guide.
Properly set valves ensure your engine breathes exactly as the engineers at BRP intended. Here are the key benefits you’ll notice immediately:
- Restored Power and Throttle Response: When valves open and close at the perfect time, you get optimal combustion. This translates directly to that crisp, snappy power you love.
- Easier Starting: Valves that are too tight can bleed off compression, making the engine notoriously hard to start, especially when cold. A quick adjustment often solves this frustrating problem.
- Improved Fuel Efficiency: A happy, efficient engine doesn’t have to work as hard. By optimizing the combustion cycle, you’ll burn fuel more completely, saving you a bit of cash at the pump.
- Reduced Engine Noise: That metallic ticking sound is often the sound of excessive clearance, or “valve lash.” Tightening it up to spec will make your engine purr.
- Prevents Serious Engine Damage: This is the big one. Valves that are too tight can’t seat properly, causing them to overheat and “burn,” a costly repair. Valves that are too loose can damage other valvetrain components over time.
Telltale Signs Your Valves Need Attention: When to Perform the Adjustment
Your Outlander is pretty good at telling you when it needs some love. Besides following the manufacturer’s recommended service intervals (check your owner’s manual!), you should be on the lookout for performance-related clues. Ignoring these can lead to more common problems with can am outlander valve adjustment down the road.
Keep an ear and a feel out for these common symptoms:
- The “Ticking” Sound: The most classic sign. An audible, rhythmic tapping or ticking noise that increases with engine RPM points directly to excessive valve clearance.
- Hard Starting: If your machine cranks and cranks before firing up, especially on a cold morning, tight valves could be the culprit.
- Noticeable Loss of Power: Does the ATV feel sluggish? Is it struggling on hills where it used to climb with ease? Improper valve timing from incorrect lash can rob your engine of significant power.
- Backfiring on Deceleration: While other issues can cause this, an exhaust valve that isn’t seating correctly can lead to unburnt fuel igniting in the hot exhaust pipe.
- You’ve Hit a Service Interval: Can-Am typically recommends a valve check and adjustment at the first service and then at regular, extended intervals thereafter. Don’t skip it!
Gearing Up: Tools and Parts You’ll Need for the Job
Having the right tools ready before you start is the key to a smooth, frustration-free job. You don’t need a professional shop, but you do need a few specific items. Think of this as your pre-flight checklist for a successful mission.
Essential Tools
Most of these are standard garage items, but one is non-negotiable.
- Feeler Gauges: This is the most critical tool. You need a metric set that covers a range from about 0.04mm to 0.30mm. Do not attempt the job without these.
- Socket & Wrench Set: A good metric set with 1/4″ and 3/8″ drives will cover everything. You’ll need specific sizes for the valve cover bolts, locknuts, and timing plugs.
- Torque Wrench: You absolutely need a torque wrench, preferably one that reads in inch-pounds (in-lbs) for the small valve cover bolts. Overtightening them can warp the cover or strip the threads.
- Screwdrivers: A flathead for prying and a Phillips for plastics.
- Pliers: Needle-nose pliers are always helpful.
- Clean Rags: You’ll need plenty to clean surfaces and wipe up any spilled oil.
- Flashlight or Headlamp: Good lighting is your best friend when looking for tiny timing marks.
Necessary Parts & Supplies
Don’t cut corners here. A few extra bucks on new parts ensures a leak-free result.
- New Valve Cover Gasket: We can’t stress this enough. Old rubber gaskets get hard and compressed. Reusing one is asking for an oil leak. Just buy a new one.
- Spark Plug O-Rings: The tubes the spark plugs sit in have O-rings at the base. It’s best practice to replace these while you have the cover off.
- Your Service Manual: This is the most important “part” of all. Always, always, always confirm the specific valve lash specs for your exact year and model Outlander.
The Complete How To Can-Am Outlander Valve Adjustment Guide
Alright, it’s time to get our hands dirty. This detailed walkthrough will cover the process for the popular Rotax V-twin engines found in most Outlanders. Remember, patience and precision are key. This is a job you measure, not eyeball.
Step 1: Preparation and Safety First
Start by parking your Outlander on level ground. The engine must be completely, 100% stone cold. Adjusting valves on a warm engine will result in incorrect clearances. We recommend letting it sit overnight.
Clean the machine thoroughly, especially the engine area. You don’t want dirt falling into your open engine. Finally, disconnect the negative terminal on your battery for safety.
Step 2: Gaining Access to the Cylinder Head
Now, start removing parts to clear a path to the valve covers. This typically involves removing the seat, side plastics, and sometimes the airbox or plastics around the fuel tank. Take your time and keep track of all your bolts and fasteners.
Step 3: Finding Top Dead Center (TDC) on the Compression Stroke
This is the most crucial step in the entire can am outlander valve adjustment guide. You must measure the clearance when the piston is at the very top of its travel and both valves are fully closed. This is Top Dead Center (TDC) on the compression stroke.
First, remove the spark plugs. This makes the engine much easier to turn over by hand. Next, locate the timing inspection plug on the magneto/stator cover (left side of the engine). Remove it. You will now be able to see the flywheel.
Using a socket on the crankshaft bolt, slowly rotate the engine counter-clockwise. Watch the intake valve rocker arm (the one closest to the intake). You will see it go down and then come back up. As it comes up, the piston is rising on its compression stroke. Continue turning slowly while peering into the timing hole. You are looking for a specific timing mark (often a “T” or a line) to align with a notch in the inspection hole. When they align, you are at TDC for that cylinder.
Step 4: Measuring and Adjusting the Valve Lash
With the engine at TDC for the cylinder you’re working on, you can now measure the clearance. Refer to your service manual for the exact specs. For many Rotax V-twins, they are roughly:
- Intake Valves: 0.06mm – 0.14mm (0.002″ – 0.006″)
- Exhaust Valves: 0.11mm – 0.19mm (0.004″ – 0.007″)
*DISCLAIMER: These are common ranges. YOU MUST VERIFY THE EXACT SPECS FOR YOUR MODEL YEAR IN A FACTORY SERVICE MANUAL.*
Take your feeler gauge and slide it between the top of the valve stem and the bottom of the adjuster screw on the rocker arm. You are looking for a slight, smooth drag. If it’s too loose or won’t fit at all, it needs adjustment.
To adjust, use a wrench to loosen the small locknut on the rocker arm. Use a small square-drive tool or a flathead screwdriver to turn the adjuster screw. Turn it in to decrease clearance and out to increase it. Adjust it until you feel that slight drag on the feeler gauge. Now, hold the adjuster screw perfectly still while you tighten the locknut. This is tricky, but vital.
Pro Tip: After tightening the locknut, re-check the clearance! The act of tightening can sometimes slightly alter the gap. Re-adjust if necessary until it’s perfect.
Step 5: Repeat for the Other Cylinder
Once the first cylinder’s intake and exhaust valves are done, you need to set the other cylinder to its TDC on the compression stroke. Rotate the crankshaft 360 degrees (one full turn) counter-clockwise until the timing mark lines up again. This will put the second cylinder at TDC, and you can repeat the measurement and adjustment process.
Step 6: Reassembly and Final Checks
With all valves adjusted, it’s time to put it all back together. Thoroughly clean the valve cover and the cylinder head mating surfaces. Install your new valve cover gasket. Reinstall the valve cover and tighten the bolts to the factory-specified torque in a crisscross pattern to ensure even pressure.
Reinstall the spark plugs, airbox, plastics, and everything else you removed. Reconnect the battery. Start the engine and listen to your much quieter, smoother-running machine. Job well done!
Sustainable Off-Roading: The Eco-Friendly Side of Valve Maintenance
Thinking about a sustainable can am outlander valve adjustment might sound odd, but it’s all connected. Off-roading is about enjoying nature, and good maintenance is a form of environmental stewardship. An eco-friendly can am outlander valve adjustment is simply a well-performed one.
When your engine is running at peak efficiency thanks to correctly adjusted valves, it burns fuel more completely. This directly translates to lower emissions and better gas mileage on the trail. You use less fuel and release fewer pollutants into the environment you’re there to enjoy.
Furthermore, this preventative maintenance extends the life of your engine, reducing the need for major repairs and the manufacturing of replacement parts. It’s a small step, but it’s part of a larger mindset of responsible ownership and riding.
Frequently Asked Questions About Can-Am Outlander Valve Adjustment
How often should I adjust the valves on my Can-Am Outlander?
You should always check them during the first service (around 10-25 hours). After that, consult your owner’s manual. A general rule of thumb is to check them every 100-150 hours or once a year, or anytime you notice symptoms like excessive ticking or hard starting.
What happens if my valve clearance is too tight or too loose?
Too loose (a large gap) is noisy and causes wear on valvetrain components, but it’s less dangerous than being too tight. Too tight (a small or no gap) is the real danger. It prevents the valve from fully seating, allowing hot combustion gases to leak past, which will quickly overheat and “burn” the valve, leading to a major loss of compression and an expensive engine repair.
Can I reuse my valve cover gasket?
We strongly advise against it. For the few dollars a new gasket costs, it’s not worth the risk of a messy oil leak that forces you to do the job all over again. Always install a new one for peace of mind.
Taking on a can am outlander valve adjustment is a huge step in becoming a more confident and capable DIY mechanic. It connects you to your machine on a deeper level and gives you the satisfaction of knowing the job was done right. Take your time, be meticulous with your measurements, and follow the steps.
Now, grab your tools, give your rig the tune-up it deserves, and enjoy the restored power and quiet operation on your next adventure. Stay safe and we’ll see you on the trail!
