On my 85 when I use the rear brakes, they don't seem to want to work very good. I can almost stand on the pedal, and they won't lock up.
I end up using my front brakes 90% of the time. I know the cable needs adjusted because I have to push the brake pedal quite a ways before I feel it begin to grab.
I'm thinking about sanding the drum to get rid of any glazing, and getting a new set of shoes. I really wish they would have made rear disk brakes on these.
On another note, can the shocks and forks be used w/o any air in them?
My front forks are a little soft, and I want to add some air to them. I'm the only rider with no luggage or bags.
What woud be a general PSI to have in them? I thought about running 5 to 7 pounds in the forks, and 3 to 5 in the shocks
. Any help will be greatly appreciated.
First step on brakes is check wear indicator arrow and gauge on rear hub.
Second -adjust nut so lever and brake rod are at an angle no greater than 90* to each other.
Third- is the actuating cam clean, lubed and moving freely.
Fourth- are the shoes and drum glazed or oil/grease contaminated.
IMHO when the rear drum brake is working properly it provides plenty of stopping power for this bike with less danger of over braking and locking up the rear wheel. Releasing the brake on a rear tire sliding to the side will often cause a highside flip as the bike violently tries to straighten out, throwing the rider off the bike. Much more likely to happen on a bike with too powerful rear brakes that are hard to feel feedback on.
Early model (85-88?) vn750`s with air valve in fork tubes can run fro 0-7.1 psi.
Later models have no air valve in forks.
Rear shock setting depend on your weight
. (usable air pressure is 0-43psi)
Clymer manual says damper preset on #2 and atmospheric pressure (0 psi) for a 150 lb rider.
At #300 lb ready to ride, and usually carrying a heavy bag or a preteen grandkid, I had the damping preset at #4 and max usable shock pressure of 43psi cold.
It was comfortable for me. YMMV
