Try using a higher octane gasoline in this ATV. Many times the pinging is due to not using a 91 or higher octane fuel. A lower fuel like 85 or 87 may not be burning off as efficiently as the 91 octane which in turn will cause the pinging.
The Polaris 550 ATV typically has an engine displacement of 550 cubic centimeters (cc). This measurement refers to the volume of the engine's cylinders, which contributes to the ATV's power and performance capabilities. Different models within the 550 range may have variations, but 550 cc is the standard for this classification.

The average top speed of a Polaris Sportsman 550 is 65 miles per hour. However, this quad can sometimes go as much as 68 miles per hour.
The 800, hands down. The 550 is actually on par with a 500 efi. However, the XP platform the 550 comes in is much better all around than the older 500/800 platform.
yes
I have had my 2010 550 XP EPS to 57 mph(94 km/h) and it still wants to go. It only has 250 miles on it yet and it may produce a few more mph but i doubt it
550 horsepower
To change the oil on a 2011 Polaris Sportsman 550, first ensure the quad is on a level surface and the engine is warm for better oil flow. Remove the oil drain plug located at the bottom of the engine and allow the old oil to fully drain into a suitable container. Replace the drain plug, then remove and replace the oil filter if necessary. Finally, refill with the recommended oil type through the dipstick tube, checking the level to ensure it’s within the proper range.

A dimming headlight on your 2000 Polaris 550 touring snowmobile could be caused by a few factors. It may be due to a weak or failing battery, which struggles to provide consistent power. Additionally, corroded or loose electrical connections and a failing voltage regulator can lead to fluctuating power levels. Checking the wiring and connections, along with testing the battery and voltage output, can help diagnose and resolve the issue.
550 + 550 = 1100
