Why is my scooter blowing white?
White smoke in mopeds is usually an indicator that coolant or moisture has entered into the combustion chamber and is evaporating into steam. Coolant and water should not be present in the combustion chamber and their presence suggests that a component like a water pump or a radiator hose is damaged or worn.
Why do scooters burn oil?
But if it’s excessive then you’ve got a burning oil problem, a rich fuel condition like noted above, a bad spark plug or a malfunctioning power valve. Leaking valve seals. Blue smoke ;in a four stroke is usually crankcase oil being burned. Leaking piston rings and/or bad valve seals can let oil get into the cylinder.
How much oil should I put in my scooter?
How Much Oil Does a 150cc Scooter Take? You’ll need around 0.8 to 0.9 liters, just under one qt. Every scooter comes with a recommended level you can fill up to. Check this level with a dipstick from time to time in order to fill it up to the given recommended level.
How much 2 stroke oil do I put in my moped?
How much oil? Most owner’s manuals will tell you, but ratios between 32:1 and 40:1 are common. Thus, your mix is 40 parts gasoline to one part oil. If you’re working with the metric system, it’s easy: 10cc of oil to 400cc of fuel.
Can I use 2-stroke oil in my moped?
Nope. Modern 2-stroke scooters use a direct oil injection system which delivers the right amount of oil directly to the engine. However do make sure that you use good quality 2-stroke oil that is made for injection systems (that’s oil injection, not fuel injection).
What happens when oil is mixed with blow by?
Mixed by a spinning crankshaft, combustion by-products churn with partially vaporized oil in a witch’s brew that, if not properly vented and managed, can be problematic. Windage is also involved in any discussion regarding crankcase pressure since oil is the viscous fluid that we must deal with.
How to avoid common causes of blow by and oil consumption?
Here are some common causes of blow-by and excessive oil consumption and how you can avoid them on your next engine build. The combustion process is never perfect. Even the best street engine never seals all that combustion pressure. A certain amount of cylinder pressure will always find its way into the oil pan.
How many quarts of oil should I add to my engine?
Steve first tested this oil pressure problem by adding a half quart (to be safe) and recorded an even greater pressure drop. He eventually drained 2 ½ quarts of oil from the engine and not only did the oil pressure stabilize, but the power improved by a solid 20 hp as well.
What kind of oil pressure does a big block Chevy have?
This may sound simple, but we’ve seen this happen many times. In a situation that recently occurred at Westech Performance, dyno operator Steve Brule’ witnessed a significant dip in oil pressure above 5,000 rpm on a 600 hp 468ci big-block Chevy.
