Modern motorcycles are incredibly reliable, but they still require you to check a few things in order to keep them running at full potential. The engine oil is one of those items you should never neglect. After all, you don’t want to run your high-revving, manufactured-to-aerospace-tolerances, and extremely-expensive-to-replace engine without the proper lubricant, do you? Additionally, an engine’s oil can reveal a good bit of information about the condition of its internals to even a novice mechanic armed with a little information.

To actually check an engine’s oil level, take a look at its owner’s manual. Seriously, it’ll outline the specifics that the manufacturer recommends – and they do vary slightly from bike-to-bike. Still, the steps do follow a rough pattern.

Make sure the engine is warmed to operating temperature. After turning it off, allow the oil to drain down from the top end by waiting a few minutes. Bikes with a sight glass require that you hold the bike level – either from the saddle or beside the bike – look at the window conveniently located on the bottom of the engine to make sure the oil level is between the two marks on the case. (Tip: If your bike has both a centerstand and a sight glass, measure it the above way and then compare it to the level shown while on the centerstand. This way you can use that level as reference so can check the oil level when it’s parked on the centerstand in your garage.)

For engines with a dipstick, check your owner’s manual to make certain how the stick is to be inserted for an accurate reading. Usually, you will wipe the stick and insert it into the case until it makes contact with the filler plug’s threads. Be sure the plug is straight and the bike is level or you may get an inaccurate reading.

If you ride your bike regularly, you should check its oil at least weekly. If you ride infrequently, consider checking before every ride. With regular checks, you are more likely to notice symptoms of little problems before they get bigger.
