After test-fitting the first cylinder I cleaned off the block with brake cleaner and compressed air to get rid of any metal chips. Then I installed the crank, rod, and test piston in each cylinder to test-fit the clearance. If you are going to grind while the crank and bearings are installed be careful to not hit them with the carbide bit and blow off the metal chips before moving the crank. Just remember if you scratch the crank, cylinder, or any bearing surface you might have to start all over. Hot tank the block after this step.
