I started working on the bike today. The left fork has a schrader valve on top. The right fork has an adjustment knob on top, 4 position. So the right fork does not take air? When I service the forks should I use ATF of 10w fork oil. I am 200 lbs. I was thinking later on I might put a CBR F3 rear shock on it. Is the f3 shock more adjustable over the origonal? What are your imputs? The bike will be my daily driver.
It's been some time since I owned a VF750 (more than 30 years) but I recall the two forks are linked by an air tube under the triple clamp. ATF is effectively a 10W oil so you can use either.
ATF is actually 7.5w. Get some 10w. A solid rod is probably a better shock than the original. The F3 shock will need to be modified to use on the VF750F. See Daugherty Motorsports.
