it wont have valves in the head. If you remove the exhaust pipe from the head and turn over the engine by hand, there will only be a piston and no valves moving.
a four stroke has a timing chain and a cam and a two stroke doesnt a two stroke has reed valves
If you look at the side of the bike there is a pipe that leads to the exaust pipe. If it is big and bulges out then its a two stroke. if its small and skinny its a four stroke. you can tell by the name to. if its a YZ250 its a two stroke. If its a YZ250F then its a four stroke.
Assuming you are referring to a street legal motorcycle (IE: Kawaski Vulcan, Ninja, etc.) these machines have four stroke engines. Dirt Bikes and such sometimes do not. Two-stroke engines generally use a fuel+oil mixture. (Such as a weed whacker) Four stroke engines generally have an oil sump. (Like a car)
first of all learn how to spell. Anyone with half a brain could tell it is a four stroke. A two stroke mixes the oil and the gas and a 4 stroke keeps them separate. A four stroke sounds much deeper than a two stroke. you should know this. Ever heard a banshee? that's what a two stroke sounds like.
Well the first necessary piece of information I would need to know is: Is it a two stroke or four stroke engine? I assume its four stroke as I'm sure you know that you need to mix two stroke oil with petrol and then put it in the tank if it's a two stroke. In that case, 25 to 30ml of two stroke oil to a litre of petrol is perfect. On the otherhand, if it is a four stroke, 300-400 ml of oil should be about right.
four
depends if it is a two stroke or four. a two stroke will not be a four stroke may i am not sure
Explain the advantages of four-stroke engine over two-stroke engine
Two Stroke Combustion Engines are now obsolete.But two stroke might come back with modifications.
You can use four stroke oil for a (very) limited period in a two stroke engine in an emergency. However it is not formulated for two stroke engines and is not recommended.
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
Four-stroke lawn mowers have a tube where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
