How Much Engine Oil Should Be Added to a Underbone Motorcycle?
2 Answers
An underbone motorcycle typically requires about 800 milliliters of engine oil per refill. The oil quantity for underbone motorcycles is generally around 800 milliliters, which can be verified using the oil dipstick or oil inspection window. Checking the Oil Level: When changing the oil, park the motorcycle on a level surface using the main stand. Remove the drain screw at the bottom right side of the engine to drain all the old oil. After reinstalling the drain screw, add approximately 800 milliliters of new oil. Insert the dipstick into the dipstick hole (push it all the way in without screwing it in), then remove it to check that the oil level is between the upper and lower marks at the end of the dipstick. Choosing a Suitable Oil Container: During hot seasons, even when using a fuel pump to fill a container with gasoline for refueling a motorcycle parked in a designated refueling area, it is essential to use a conductive container made of materials like iron or aluminum. Plastic containers must not be used as oil containers, as they can easily cause static electricity reactions, leading to fires.
As a veteran rider with over a decade of experience on underbone motorcycles, I must say the engine oil capacity can't be generalized. There are significant differences between various underbone models. For common small-displacement bikes like Honda underbones, it's typically around 0.8 to 1.0 liters, but my old motorcycle's manual specifies 1.1 liters. The most important thing for beginners to remember is to check the dipstick: After warming up the engine and waiting a few minutes, wipe the dipstick clean and reinsert it - the oil level should be between the MAX and MIN marks. Too much oil causes smoking and carbon buildup, while too little leads to engine component wear, which is troublesome to repair. Whenever I do DIY maintenance, I always start by adding 0.7 liters first, then gradually top up to the upper limit. Regular oil changes are even more crucial - using 10W-40 full synthetic oil provides better engine protection, and for city riding, changing every 3,000 kilometers is sufficient.
