How Do I Check the Oil in Suzuki Bikes

by Contributing Writer; Updated June 12, 2017

Although Suzuki bike line of cruiser motorcycles resemble American-made V-twin motorcycles, Suzuki bike engineers have designed their machines to be easy to maintain and own. Checking the oil level on one of the Suzuki bike motorcycles is as easy as finding its oil level lens, a round glass port mounted on the motor's left crankcase cover. The oil level lens has a pair of marks imprinted on the top and bottom of the lens, indicating the amount of oil in the motor, eliminating the need for a messy dipstick.

 How Do I Check the Oil in a Suzuki Boulevard?

Start the motorcycle and allow its motor to warm up for five minutes. This will allow the oil within the motor to expand slightly, providing you with an accurate reading at the oil level lens. Stop the motor and turn off the ignition.

Kneel to the left of the motorcycle and locate the oil level lens on the left crankcase cover. Grasp the motorcycle's frame with one hand and the left handlebar with the other. Push the motorcycle into an upright position and hold it there to fill the oil level lens.

Take note of the oil level in relation to the upper and lower marks imprinted on the lens. For best results, the oil level should be centered between both marks. Lower the motorcycle onto its kickstand.

Raise or lower the oil level as needed to bring the oil level to the center of the lens. Add oil into the oil filler above the oil level lens, pouring in small amounts of oil at a time to gradually raise the oil level. Siphon excess oil out through the oil filler using a hand pump to lower the oil level.

 How to Check the Oil in an M109R

Park your M109R in a well-ventilated area to prevent dangerous exhaust buildup. Start the bike and allow it to idle for 15 minutes.

Shut off the ignition and let the bike sit for three minutes. Stand the bike as upright as possible, using a portable motorcycle lift if possible.

Locate the dipstick on the motor and unscrew it. The dipstick is located on the left side of the bike when you are sitting on it, tucked just under the cylinder. Wipe the oil off the dipstick with a rag.

Reinsert the dipstick in the block without tightening it. Pull the dipstick out and check the oil level according to the webbed portion. Reinsert the dipstick and tighten it.

Items you will need

  • Rag

  • Portable motorcycle lift

 How to Check the Oil in an Intruder Motorcycle

Start up your Intruder and let the engine idle for five to 10 minutes to allow the oil to heat up and increase its viscosity, then turn off the motorcycle.

Remove the oil filler cap found on the right-hand side of the engine and slowly pull it out.

Clean the dipstick that is built-in to the oil filler cap by wiping it with a paper towel.

Insert the cap with the clean dipstick all the way into the engine and remove it.

Read the engine oil level that appears on the dipstick when you pull it out. The oil level should be at the notch on the dipstick. If it is lower than the notch, you will need to add more oil.

  • Paper towel

 How to Check the Oil in a Suzuki Motorcycle

Warm your motorcycle to operating temperature by starting the motor and letting the oil warm up, or by taking a short ride. The oil will expand slightly and flow better to give you a more accurate reading.

Park the motorcycle on a flat, level surface and turn the ignition switch to the "OFF" position.

Position yourself to the left of your Suzuki motorcycle, crouching slightly to locate the oil sight glass on the motor. The sight glass is a round port usually placed just below and to the left of the clutch cover.

Maintain your position and slowly lift the motorcycle off of its side stand, holding the bike in a vertical position.

As the oil fills the sight glass, it will stop somewhere between a set of marks indicating the amount of oil in the motor. Optimally, the oil level should float just between the two marks. If the oil level is below the lower mark, you may need to add more oil slowly until it is between the two marks.

Take note of the color and opacity of the oil. If the oil appears to be cloudy or contaminated, replace the oil and oil filter immediately.

Slowly place the motorcycle back onto its side stand.
