I just bought a 2001 400ex the bike is in great shape and runs awesome I ordered a oil filter from Magic Racing and I'm going to change the oil as soon as it comes.....the bike didn't come with an owners manual so how much oil does it take?

Thanx
Chris

 

after draining ---------------1.9 QT
after drain and filter-------1.95 QT
after disassembly---------2.3 QT



you do know that there is more than one drain plug right?

 

Yes just like on my KFX 400 one on the motor and one on the oil tank! LOL
