While using a ratcheting wrench to pull the top end off my 06' 450F, one of the teeth on the ratchet fell off and onto the crank and into the bottom end.. Today I attempted to use oil and deisel fuel to flush the motor hoping I could get the peice to come out of the drain plug.. I did this atleast 7 times...NO luck... While I had the bottom end filled with fluid, I put the bike in gear and rotated the rear tire to spin things around in an effort to move the piece towards the drain plug..I spun it in every gear and everything worked smoothly..Still no luck at the drain plug.. So now im at a loss for what to do. I feel like I should split the cases, but after looking at the design of the cases it appears there is a litte dip where the oil pick up and drain plug sits.. Is it possible this little piece of pot metal is just sitting down there? If so, would it pose any risk when riding the bike??? If i had my own place, I would take some time to split the cases ad hunt it down, however, I dont have that option right now.. Any thoughts on what I should do??
