yes all Yamaha dirt bikes are fuel injected
A Yamaha ATV that small is carbureted , not fuel injected.
Carborated
The manual recommended fuel for a Yamaha Raptor 660 is regular unleaded gasoline. Higher octane unleaded gas will likely improve performance.
Carburated
it is oil injected
I think this quite likely as it is more powerful.
"2008 Kawasaki Brute Force Fuel Injected" ??? Best selling sports atv is the yamaha raptor. Best selling 4x4 according to what i can find online - polaris sportsman 500 ! Kawasaki - lol...
Regular fuel will do fine but a higher octane is always better. As far as oil, you can't go wrong with the Yamaha brand.
in 2002 and 2003 they did the switch but some people might sill say it wasnt truly fuel injected till 2004
The yzf is fuel injected no carburetors
The Yamaha Raider does not have a idle adjustment based on the fact it has no carbs. It is fuel injected and auto adjusts based on the temperature and fuel delivery.
