    Replace fork fluid 95 Nighthawk.

    Yes drain fluid and refill from the top. Do not remove both fork caps at the same time as front end will drop. Or you can support front end from ceiling joist. I have a 4 inch pvc spacer in my 92 nighthawk forks stiffens up the front forks. 350 to 400cc of fork oil or measure what you drain...

    Starter motors have continuity?

    Ok I don’t believe you have 3 bad starter motors. I believe user error. Positive must be isolated from ground terminal you are doing a dead short. Sounds like a user problem, please step back and rethink.

    Tank liner suggestions?

    Good advice. Take tank off. Be careful with cleaning solution. I use some 6 inch small loop chains from ACE hardware drop in the tank and rotate/ shake tank to knock any rust free. You should have an inline clear fuel filter to see if any rust is getting out of the tank. Plus the fuel...

    Digital Speedometer Speed Sensor Conversion

    "the automatic shutoff is not really important to the way the bike functions," This is not correct and I speak from experience: My 1992 Nighthawk. (CB750) had a bad fuel petcock would not hold vacuum and caused starting problems long cranking, slow to idle up on cold startups. I thought it was...

    Looking at buying please advise

    92 Nighthawk here and the valves do not need to adjusted ever. Hydraulic lifers so the oil being clean is very important. Yes 50k is high mileage but depending on owner maintenance is not a problem. 31k is much better. 12k would be great if kept in running condition. Avoid the bike with 5k...
