prise up the dust seal and cut a strip of cloth about a inch wide by about 4 inches long cover it in grease and pack it into the fork where the seal is push the dust seal back down and wipe any excess grease away pump the forks a few times and clean any grease that shows on the leg then your good to go i have done this many times and it works a treat , i have had years out of forks with this done and no more leaks . i do this now to every bike as the light smear of grease that is wiped on with the cloth lubes the seal , since i have started doing this i have never had a fork seal go , been doing it for about 30 years red rubber grease is about the best for it , it is worth a try so get you by till you get a chance to replace them
