Im gonna pull it apart. Heads anyways and see if theres any signs of sand in there. Wanting to know what would be the best way to clean the case. Flushing it with something, solvent, air, etc. Also this will be my first venture working on a bike. Have some mechanical knowledge. Can anyone steer me to a site that has the procedure of taking off the head and etc. My buddy says its cake but I like to have my ducks in order so to speak.
