Well as you might of guessed it, it's time to change my oil. I know the whole process of it, I just don't know what kind of oil filter to get for my 400ex. Can someone name off some brands and model or serial # of filter that I should get? I would greatly appreciate it. Thank you.

I would either go to your local honda dealer or get visit Motorcycle Parts, Motorcycle Accessories ? BikeBandit.com and order one from there.

I always just went to the Honda dealer and bought the OEM filters.

Make sure you get oil that is wet clutch compatible. AMSOIL Formula 4-Stroke Synthetic Motor Oil is a great choice for your 400ex. Let me know if I can help with the oil.
