Why does my motorcycle spit and sputter?
There are several reasons why a motorcycle sputters. The most common reasons are carburetor issues such as a vacuum leak, fuel leak, or tuning issues. Other culprits could include corroded or cracked spark plugs or spark plug wires, a faulty ignition coil, a clogged air filter, or engine timing issues.
What should I do if my motorcycle is sputtering?
Start by checking the easiest spot first which would be the spark plugs. Take out your spark plugs and make sure there is no nasty build up on them or any type of corrosion. Also make sure the point isn’t worn down and that the gap between the center and the ground electrode is the appropriate distance.
What causes a carburetor on a motorcycle to sputter?

Why does my bike stop after 20 minutes?
My bike will run for about 20 minutes or so, then start losing power and missing and sputtering. Then it stops. I wait 2 minutes, and it runs again for another 20 or so minutes. It’s not the fuel valve (tried normal and Reserve), and it’s not the plugs or wires (runs fine when running).
