Allright i spent like 10 frigen hours cleaning this bad boy, found out that i have a newer cylinder says 06 on the side and looks cleaner, the other cylinder says 04 and looks older. also my clutch is newer febuary 26? 2006 is there a way to check if i have the updated crank without takin the cases apart? also ill post pics of the "clean" engine as clean as i could get the bottom end without taking it apart.
