How do I stop my ATV from smoking?
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. When the ATV is is warmed up, the oil burns off better, and the smoke goes away. In this situation, it is best to do a compression test and a leak down test.
Why is my 400ex smoking after rebuild?
Sounds like you may have an issue with your rings. I would pull the head, and inspect the cylinder walls. If a ring is causing that much smoke, it’s likely that it scuffed the cylinder walls. Other possibility is valve seals.
