how much oil do i need to change the oil on my 2005 kawasaki 500 motorcycle?

i just bought the bike and i dont have the manual. and what type of oil do i need?

I put 10 40W semi Oil onDrain the whole lot out by the Sump bolt - alot will come out.Have MIN 4 Liters of oil.......... Put in 2 Liters (on bottle)Get someone to sit on it - or if you have a abba stand make sure its centered - turn the bike on and let run for 3 mins - turn off and cool for 3 mins - you will see the oil return to the glass window.If its not between to Min/Max lines add a bit more - but add slowly and stop, again if need be.Again do the 3 min stop/start and see where the oil sits.The 3 min gap gets all the oil to where its needed - then to drain again.This will give you a good estimate of oil to use.I changed my ZX6R yesterday and 3 Ltrs were used.

Buying 4 quarts is a good idea, it will probably not use all of it, but then you'll have some for top off.As for what kind you definitely want motorcycle specific oil to prevent wet clutch slippage due to friction modifiers used in automotive oils. Also a synthetic will stand up to heat better and shearing forces generated by your transmission gears. Most likely a 10W-40 viscosity for your Kawasaki.Here is a link to 26 different motorcycle oils compared including Amsoil, Mobil-1, Motul, Castrol, etc: http://www.amsoil.com/lit/g2156.pdfIf you decide on Amsoil, here's my Amsoil website: http://www.number1synthetic.comGood luck! Congrats on your first bike and learning to work on it yourself.
