yamaha has a master cylinder repair kit available for that machine. comes with a new plunger and some o rings, pretty simple install. you will need a vaccuum bleeder to complete the repair.
hey thanks for the advice. I got it fixed though. I had bad advice to begin with. Someone told me to slowly pump the brake lever 15-20 times then bleed the valve and so on until you got the air out and built up pressure. Weill, it pi$$ed me off long enough so I started pumping the lever fast and hard and the pressure started building up right away.
