What causes smoke in the exhaust of a motorcycle?
Check if there is too much oil in the oil reservoir and, if so, drain the excess oil and see if the exhaust continues to smoke. This is the most obvious cause of smoke when the engine burns oil. Inspect the cylinder heads, seals and pistons for wear.
Why does my motorcycle have a lot of Blue Smoke?

Why does my quad bike smoke when I start it?
If the smoke only occurs when you start your quad, but doesn’t happen during the ride, there is nothing to worry about as it is just condensation burning off. If the smoke is excessive early in your ride, but then goes away later on, you are most likely dealing with bad piston rings or valve guides/seals.
What to do when your motorcycle starts smoking?
Warm up the engine then put the piston at the top dead center on the compression stroke so both valves are closed. Pump air into the cylinder through the spark-plug hole and measure the leak down with the attached gauge.
What makes a motorcycle engine overheat the most?
Motorcycles with air cooled engines are the most to suffer. Liquid cooled engines have coolant running in and out of the engine keeping them cool and a radiator fan to keep the radiator from heating up and failing to cool the engine efficiently. Let us first look into the causes of why most motorcycles suffer from overheating.
What should I do if my MerCruiser runs too hot?
All it takes is 45 seconds of running dryand the impellar is ruined. Make sure you have a good set of flushett muffs that won’t fall off while you are running on the hose.

Why does my dirt bike have blue smoke in it?
You can see the blue looking smoke in dirt bikes that have unwanted oil mixing with the air-fuel mixture.

Why is my water pump on my dirt bike overheating?
A cause of overheating may be, although not as often, a broken impeller. If it’s cracked or part of it is broken off (yes, even one small piece) it won’t provide sufficient cooling to the bike. If none of the above are the problem, just pop off the water pump cover to see if the impeller is bad or if there’s corrosion.
