Left front for leaking on 1993 yamaha fzr 600

Each fork has an outer dust seal, and an inner seal inside of that. Dirt gets between the seal lip and the fork slider and causes the oil to escape. The fix is to have them (Both sides) replaced. You need a fork seal driver tool (Size specific for the size of the fork) and something to measure out the oil amount. It's not an easy job, if you have never done it. Also... if the oil has never been changed, it's due.

it sounds like your fork seal has failed,it wont affect your brakes but will make your front suspension feel a wee bit "soggy"and will affect your handling,i would suggest getting the seal replaced as evetually the oil from the faulty seal will contaminate your brake pads that will affect your braking performance,replacing the seal,sooner rather than later ,would be a wise move..hope this helps...cheers

check first to see if the leaking fork has any rust pitting on the chrome,if it has and its a very small blemish then fettle it off first,and just replace the leaking seal,as the saying goes..if it aint broke dont fix it,if the seals had been in the forks for years and the bike not used then consider replacing both..

change the oil seals and oil in the fork,and avoid wheelies on the bike and off road biking
