How to replace fork seals on 1984 vt750 honda shadow

This type of R/R is what I call a straight monkey see...monkey do repair. Undo the drain screw on each fork and drain oil. The bike must be high enough off the ground to slide the sliders off unimpeded. From there let pressure off via the schrader valves on the forks, if so equipped. Remove wheel and unbolt anything attached to sliders because these must be taken to the bench. At the bottom of each slider, remove bolt and slide the slider off fork tube. Take slider to bench and remove internal snap ring and carefully pry the old seals out without damaging anything. Grease the new seals and carefully tap seal into slider evenly. A deep well socket can be used to tap it all the way in. From there it's reverse procedure. Add fork oil to specs.

You can purchase new seals at the Honda dealer and stop the leak. Then you will not have to worry about it. Should be similar to the 1983 VT750 clutch slave that can be seen here. http://www.bikebandit.com/houseofmotorcycles/1983-honda-vt750c-shadow/o/m2877#sch5465

No special tools other than maybe an air-impact whench to remove the Allen bolts in the bottom of the fork sliders. These hold the botom of the metering rods into the forks and will spin if you don't have Honda's special tool which fits down the inside of the fork tube. Air wrench spins them off no problem.

V65 Sabre has fule filter behind battery and fule shutoff valve under seat.

Loosen upper triple-clamp pinch bolt before trying to remove fork cap.

Drain oil out of fork, then remove axle and access the metering rod holder bolt at the bottom inside the area whre the axles goes. Use an air wrench and appropriate Allen bit.

Remove fork cap, being careful of the spring pressure.

Remove fork from bike and take out spring and metering rod. Pry dust seal out of fork slider and use snap-ring pliers to remove retainer from beneath dust seal. Use fork tube to hammer seal and slider bushing out of fork slider.

Replace seal and use old seal to cushion it. Make a fork seal driver from split PVC pipe and hammer seal and slider bushing back in. Remove old seal and replace retainer clip. Install dust seal.

Reinstall on bike and install spring. With bike properly supported, stand on pegs and use ratchet, extension and socket to apply pressure to spring and thread cap carefully onto top of fork tube. Reinstall metering rod holder bolt in bottom of fork using thread-locker and air-wrench. Don't over-tighten; just ue high speed to conteract tendency of metering rod to spin inside slider.

Remove fork cap again and fill to appropriate level with 5 weight fork oil (Pro Honda SS-7 or equivalent). Use turkey-baster to remove excess oil to proper level (5 1/2 to 7 inches fully compressed depending on damping quality desired).

Based on the information you have provided I suspect a bent shift fork in your transmission. To fix it you will have to take the transmission cover off and get at that fork. Replacing the fork is probably easiest, the labor to get to it is the expensive part.
