I DON´T KNOW WHAT NUMBER OF SEALS YOUR FZR´S FORKS ARE, BUT THIS IS SOMETHNIG YOU CAN SEE BY YOURSELF WHEN YOU´LL REMOVE THEM. ON THE TOP SIDE, THEY HAVE SMALL NUMBERS WICH INDICATE THEIR DIMENTIONS. YOU CAN THEN GO WITH THEESE NUMBERS AND BYE THE NEW ONES. ONCE YOU HAVE THEM OUT, CLEAN THEM WELL AND LOOK FOR THEESE NUMBERS. FOR EXAMPLE, THEY MIGHT WRITE: 50-38-10. THE FIRST NUMBER IS THE OUTERNAL DIAMETER IN mm, THE 2ND IS THE INTERNAL DIAMETER AND THE LAST IS THE THICKNESS OF THE SEAL. YOU DON´T HAVE TO GO AND BYE THEM BY A YAMAHA DEALER. OTHER STORES ARE THE SAME. AND THE QUALITY IT´S MAYBE BETTER, BELIEVE ME. NOW, THERE ARE TWO WAYS TO REMOVE THE SEALS:THE EASY AND THE HARD WAY. I BET YOU WANT TO KNOW THE EASY. BUT KEEP IN MIND THAT YOU MUST HAVE BASIC KNOWLEDGE OF REPAIRMENTS. IF NOT, DON´T TRY IT BY YOURSELF. THE EASY WAY IS TO REMOVE THE FRONT FORKS COMPLETELY OF YOUR BIKE. THAT INCLUDES CLIP ONS, FAIRING MASK MAYBE, FRONT WHEEL ETC. ONCE YOU HAVE THE FORKS OFF THE BIKE, TAKE A SMALL THIN SCREWDRIVER AND REMOVE THE OLD SEALS. CLEAN WELL THE FORKS AND PUT ON THE NEWS. BE VERY CAREFULL NOT TO REMOVE THE SPRING ON THE INTERNAL OF EVERY SEAL. PUT THE FORKS ON THE BIKE ON THEIR PREVIOUS POSITION. GOOD LUCK
