Why does my outboard motor smoke when I start it up?
A common reason is that if you leave the outboard tilted down after running it, there can be oil build up in the cylinders.

That should resolve the smoking.
Why does my two stroke engine have blue smoke?

Why does my four stroke motor smoke oil?
A Four Stroke, on the other hand, has an oil pan; where there is an oil pump that pumps the oil up into the powerhead, ( What is an Outboard Powerhead ), which lubricates all of the components without burning the oil and cuts down on the smoke.

What causes smoke coming out of exhaust pipe on dirt bike?
When cylinders go bad, gaskets leak or really anything internal on your dirt bike or ATV engine that allows for flawed combustion of fuel or any fluid used for the proper function of a 2-stroke or 4-stroke the telltale sign is usually seen coming out of the exhaust pipe.
Where does the smoke come from on a Honda 4 stroke?
On a 4-Stroke (usually Honda) the smoke typically blows out of the crankcase vent rather than the exhaust pipe. When faced with a smoke issue, don’t continue riding. Routine maintenance helps prevent many smoke related issues but old seals or gaskets and certainly a big crash can cause fluid leaks.
