I have a 2005 wr450 that i subbed in sandy water. After weeks of hours and hours of flushing and cleaning, there is still sand in the oil pan, frame and other places. So I plan to remove the engine and break her down, hopefully just a top end rebuild. I'm barely even a rookie mechanic, but i am somewhat decent at these things...i need some help though. any tips, tricks, pitfalls, shortcuts or comments on engine removal or any other parts of the process?
