Importance of engine oil

  • Motor oil is usually regarded as the vehicle’s engine’s lifeblood.
  • Whether you like an antique Italian Ducati or a Harley-Davidson aficionado, engine oil is essential for keeping your engine parts cool.
  • Engine oil reduces friction and prevents excessive power loss.
  • A well-lubricated engine will burn fuel more efficiently and thus function effectively.
  • The engine oil helps to balance all of the bike’s parts by changing the gasoline into a moving force.

Does a dirt bike have an oil filter?

Every bike model has its own set of settings, although practically all bikes include an oil filter or drain plug on the left side of the engine. On the oil filter cover, you may possibly notice two eight-millimeter bolts.

We also have a query: “Do these Chinese 110-125cc motors have an oil filter?” The answer is that they do not have a changeable oil filter like your car. They do have a screen installed beneath the oil pump pickup.

What happens if you don’t change your dirt bike oil?

  • If you fail to change the dirt oil in your motorcycle, the engine will overheat.
  • The bike’s fuel efficiency may decline, making it less efficient.
  • You will notice friction between its moving parts.
  • Over time, dirt or chemical substances might build, and block the oil lines.
  • There is also a risk of corrosion as there is not enough lubrication.
  • This will eventually fail to the point of irreparable damage.

As a result, according to the dirt bike manual, you should change the engine oil, oil filter, and transmission oil after six races, or every 15 hours.

Why do dirt bikes need oil changes so often?

Change Oil From Dirt Bike – 10 Easy Steps

how to change oil on dirt bike

Give a check before starting

  • Before beginning to change the dirty oil, the first responsibility is to check the oil level and condition.
  • Muddy oil and oil-containing metallic particles are other signs of a problem.
  • Check for any leakage or burned parts.
  • After you’ve confirmed that the oil in there isn’t suggesting any obvious bad engine issues, the oil change can start.

Warm Up your motorcycle 

  • Make sure you warm the engine before changing the oil.
  • Warm up the bike to “operating temperature,” then ride it for 30 minutes before changing the oil.
  • But never start an air-cooled motorcycle and let it rest for thirty minutes, as there is a massive risk of damaging your bike.

Clear your workstation

  • Make sure the oil-change area is clean and clear of dirt and other pollutants before you start.
  • You must properly set up the workstation by gathering the necessary items.

Remove oil filter or drain plug 

  • Remove any items that restrict access to the filler, drain plug, and oil filter.
  • Allow the oil to drain while you work on cleaning the oil filter.
  • You might need to uncover the engine guard covering the filter cover.
  • To remove the oil filter cover or cap, you’ll need to use a torque wrench. Also, make sure the bolt is not over-tightened.
  • Roll the engine with your hand to push out further oil.
  • Now, clean around the oil filter cover and inside the container where the filter goes.
  • You can use a paper towel or a lint-free rag to clean the filter.

Drain the old oil

  • Remove the oil-fill plug first, then the drain plug with a socket wrench.
  • Your oil pan will get all the drained oil.
  • Place the drain pan behind the drain plug to catch the used oil.
  • Determine the filling and drain plugs at the top and bottom of the motor box.
  • Allow the old oil to drain for 5 to 10 minutes, or until the stream has dropped.
  • To empty the oil totally, kick the bike over 5 times.
  • Hold the arm to ensure you don’t splash oil on yourself and unscrew the plug by hand.
  • However, you can purchase magnetic-tipped drain plugs that will assist you in catching all of the metal shavings within the gearbox.

New filter installation

  • The old filter should be disconnected from the bike, and then the new one should be installed.
  • Replace all of the covering O-rings if you have an inside filter.
  • Give a small amount of drain pan oil or grease to the O-ring on your new filter.
  • The oil makes it easier for the filter to slide into the slot and ensures a tight fit.
  • Also, put a little oil directly into the filter to prevent your engine from running dry when you start it.
  • Install the filter by hand and crank it until a certain resistance is detected.

Reinstall your drain plug properly

  • If your drain plug has a cover, change it.
  • You also need to screw the drain plug in by hand until snug to avoid the chance of cross-threading.
  • Finish tightening with a torque wrench, or tighten the drain stopper only 1/4-turn from hand-snug with a box or socket wrench.
  • Tightening your drain cap with a torque wrench at 14 to 16 foot-pounds of torque is the most secure method.
  • Remember, overtightening is not permitted!

Put an adequate amount of new motorcycle oil

  • Determine how much oil will be required to fill the engine.
  • The engine will have a sight glass or a dipstick to detect the oil fill level.
  • Fill a funnel halfway with the appropriate quantity of oil.
  • Continue to add oil until the level is somewhere between “Low” and “Full.”
  • Install the filter cover with the engine guard after adding oil to the O-ring.
  • So, properly refill the filter with fresh and clean oil to reduce the amount of time the engine runs without oil.

Run the engine

  • Install the correct amount and thickness of the oil, as recommended in your owner’s manual.
  • Check for oil pressure by visually inspecting the oil pressure light or verifying the pressure on the gauge.
  • Now it’s time to double-check the oil level.
  • If required, put oil or remove oil.
  • For unintentionally overfilled oil, make sure you drain some oil.

How much oil do you put in a 4-stroke dirt bike?

The most common weight for dirt bikes is 10w-40. This is to say, 20L of fuel to 1L of oil. ATF, or light motor oil, is often used. Because this oil is exposed to less heat and contaminants than engine oil in a four-stroke engine, it does not require regular oil changes as well.

How often to change 4 strokes of dirt bike oil?

4-stroke engine Riders should change the oil every five to ten hours to maintain an even balance between cost and proper bike repair and maintenance routine.

What oil does a 2-stroke need?

Semi-synthetic, synthetic, castor, or petroleum 2-stroke oil, also known as two-cycle oil or 2t oil base, can be used. Modern two-strokes use synthetic oil to reduce high emissions and greasy deposits on spark plugs. Simply, we mix the engine oil with gasoline or petrol at the volumetric fuel-to-engine oil ratio that typically runs from 16:1 to 100:1.
