How do you change fork seals on 1985 Honda 650 nighthawk?

Answer 1

You need special tools for this job. They are fork seal drivers and lower fork bolt extension handle. You can potentially make these or borrow if you don't have them but a word of warning, don't attempt to do this unless you have all the right tools. Remove the front wheel, then remove forks from the bike frame. They are held in place by clamps. The bike has to be suspended by a rope or similar. Equally, jack the bike off the floor but be careful it does not fall. Release fork oil by removing the drainage bolts on the lower end of each front fork. Remove the top lug nuts from each fork. Be careful because the spring will push the bolts and washers out by considerable force. Remove everything from each fork by inverting them, drop the contents on a clean surface, waxed paper or similar. You need a long extension such as a shaft to get to the nut at the bottom of each fork to loosen and remove the nut that holds the tube assembly together. Seal drivers are needed to remove the fork seals. Put new fork seals in place, then reassemble, finally pouring about 5 ounces of fork oil or brake fluid into each fork. Then use compressed air to put the proper air pressure in the shocks by way of the air vents. Pressure should be 10-12 psi.
