-As a parting tip,Air is fairly easy to prove. Have an assistant pump up the pedal until it is fairly hard, and hold the pedal down. Now, you, standing beside the drivers fender, lift the M/C cover, and peek under it. Then ask your assistant to remove a tiny amount of pedal pressure. You will be watching the fluid in the reservoir.If nothing is happening, reduce pedal pressure a tiny bit at a time until the fluid appears to boil. The boiling is the fluid returning to the bowl.It should be visible but modest. If you get a geyser, thats almost a sure proof that there is air in there somewhere.
