Remove the air cap valve cover from the top right fork and by doing so the air pressure inside the fork will fall to zero. dump the pressure just like letting air out of a tire. Next, remove the hose between the front forks. At this point you can make things easier by placing a floor jack on wheels under the bike to lift the front wheel off the ground but loosen the main front fork caps before you jack the bike up. Jacking the bike up means less spring pressure inside the forks, so it will be easier to remove the caps. Now remove the fork caps from both forks but be careful as the spring may shoot out. Get a vessel to put under the forks and drain off all fluid. Lower the bike to floor or ground level. Restore drain plugs into their original position. Next, add 10.2oz of ATF brake fluid to each fork. Put the air caps on and tighten them well. Reinstall hose between front forks. Finally, you must pressurize the forks. Do this with an air pump such as is commonly found at gas stations or with a manual pump that has an air gauge. The correct pressure for each fork is 10-16 psi, according to how stiff you want the forks to be.

To add fork oil to a 1982 Honda Nighthawk 750, first, ensure the motorcycle is on a stable stand and the front wheel is off the ground. Remove the fork caps using a socket wrench, then carefully pull out the fork tubes. Drain any old oil, and using a funnel, refill each fork tube with the appropriate type and amount of new fork oil, typically around 10-12 ounces depending on the model. Reassemble the forks by replacing the tubes and caps, ensuring everything is tightened securely before lowering the bike.
