8 Ways to Prep Your Snowmobile

Ok, I’m late posting this one but February is our busiest month for snowmobile oil as our customers venture out west betwixt now and the end of March. Some great snow to play in at the moment!

Avid riders are already getting their snowmobiles ready for winter. Soon it’ll be time to hit the trails or take to the mountains for the first ride of the season. Nothing ruins a ride more than a breakdown, so we put together some tips to help you get your snowmobile ready for winter.

Check the spark plugs

Inspect spark-plug and wire condition. Ski-Doo E-TEC engines require indexing if removed or replaced, so be sure to check your owner’s manual for proper instructions. They must be set facing the right direction and depth. Replace plugs that appear excessively dirty or worn along with any worn or frayed wires.

Inspect clutches and suspension

Check clutches, the drive belt and suspension for wear and tear. Greasing (everyone always forgets!) and inspecting the suspension components and slides (hyfax) are a great idea. Slides typically have a small line across them indicating when they are worn out. If they are below the line at all, replace them.

Items to check in the suspension include loose or worn parts and missing or loose idler wheels. Inspecting and cleaning the clutches and belt are also a necessary maintenance item. Remove any belt dust or rubber from the clutch sheaves.

Adjust track and check skis

Check your track for proper tension and make sure bolts are tight. Look for worn or missing lugs.

Don’t be that guy (or gal) who everyone has to bail out of trouble at every apex.

On the skis, look for any gouges, cuts or corrosion and make sure the runners are straight and still have carbide on them. The carbide edge allows the skis to bite into the trail and turn better.

Let there be light

Make sure your electrical system is up to par. Inspect the ignition and look for any warning lights that can signal problems. Check high/low-beam headlights and brake lights to ensure the bulbs haven’t burnt out.

Check the oil and filter

If you’re riding a four-stroke and didn’t do it last spring, change the oil and filter.

On two-strokes, make sure to top-off the oil reservoir and use an oil with excellent cold-flow properties for best protection. Inspect the exhaust power valves and clean them if needed. If your power valves are sticking, switch to a high-quality two-stroke oil proven to prevent power-valve sticking, like AMSOIL INTERCEPTOR Synthetic 2-Stroke Oil.

Inspect the fuel system

Check the fuel tank along with the fuel and oil lines for cracks or leaks. Unless you used a stabilizer such as A MSOIL Gasoline Stabilizer, empty the fuel tank and replace with fresh fuel. Clean your carburetor and make sure it’s adjusted properly to prevent performance issues or breakdowns. AMSOIL Power Foam is excellent for cleaning carbs.

Change the chaincase oil

It’s best to change chaincase oil annually, preferably in spring after riding season is over. Chains and gears create metal particles that need to be removed from the fluid regularly lest they build-up and cause bigger problems down the trail. We have just the oil for this important step: AMSOIL Synthetic Chaincase & Gear Oil.

Get there and be prepared

If using a trailer, ensure everything is good to go. Before you load up, inspect the tires, bearings, hitch, safety chains, axle, springs, bed, cover, lights and electrical components.

Prepare for emergencies

Anything can happen, so be prepared. When getting your snowmobile ready for winter, it’s always a good idea to bring fire-starting materials, like a lighter, along with dry clothes, work gloves, water, an extra two strap, granola bars, lip balm and any other essentials you deem necessary to have on hand if you end up stranded.

How Engine Wear & Deposits Kill Horsepower

Common Engine Wear & Deposits Will Kill Horsepower

John Baker|Oct 25, 2017 10:48 AM – Posted August 2021 (Sorry Jon – we forgot to post your blog.)

Most people equate engine wear and deposits with a sudden, catastrophic engine failure that leaves you stranded alongside the road. In reality, wear and deposits are more likely to erode engine power and efficiency over time. Here’s how it works and what you can do about it.

Engine compression = power

For your engine to produce maximum power, the combustion chamber must seal completely during the compression and combustion strokes. Wear and deposits can prevent the valves or piston rings from sealing, allowing pressurized gases to escape the combustion chamber and take potential engine power with them.

To illustrate, imagine using a hydraulic floor jack. Pumping the handle will raise the vehicle as long as the release valve is tightly seated and doesn’t leak. A poorly sealed release valve, however, allows pressure to escape, causing the vehicle to sink to the ground no matter how much you pump the jack handle.

The same principle applies inside your engine. If some of the pressure created during the compression and combustion strokes is lost due to valves and piston rings that don’t seal completely, the engine will create less power.

Wear & deposits reduce compression

Over time, deposits or valve wear can prevent the valves from closing completely, interfering with a good seal. Wear can also interfere with proper valve operation, disrupting optimum fuel/air flow.

Worn or stuck piston rings produce the same effect. The rings are designed to move freely in their grooves and press tightly against the cylinder wall. They should form a seal that prevents fuel/air from escaping. Ring wear can interfere with formation of a tight seal. Likewise, deposit buildup can cause the rings to stick in their grooves, also preventing a good seal. As a result, some fuel/air escapes the combustion chamber during compression, reducing power. On the combustion stroke, pressurized gases can blow by the rings and travel down the cylinder wall and into the oil sump, taking potential power with them. This is what’s meant when someone says an engine has lost compression.
