What might be wrong with your engine if the white smoke is pouring out the tail pipe?
Wouldn't it be the hocus-pocus elixir you poured into the tank?
That all depends. Too much Seafoam may cause the engine on our bikes not to run properly, but not pour out large plumes of white smoke like the cars in the Seafoam videos. They are pouring a large amount of Seafoam straight into the intake and some are even putting it in the oil.
What does it mean if your Exhaust Smokes Excessively:
Piston oil ring worn
Valve oil seal damaged
Valve guide worn
Engine oil level too high Note: Too much ethanol (like 100%) can cause light whispers of smoke and an inability to start the bike.
Condensation in the winter during start up can be seen as light whispers of what appears to be white smoke.
Air cleaner clogged
Main jet too large or fallen off
Choke plunger stuck open
Fuel level in carburetor float bowl too high
Main jet too small
Fuel level in carburetor float bowl too low
Air cleaner duct loose
Air cleaner poorly sealed or missing
