1984 vf 700

im rebuilding the front forks on my bike and i was woundering if somebody can tell me how much shock oil and how much nitrogen goes in them?

 

Are you sure the front forks are nitrogen charged? I figured they were just oil and air gap like most conventional forks. Just assuming here though.

 

yeah pretty sure the are i was told the nitrogen is better for the seals and works better with the adjusters on the forks

 

Well, stock form its air/tranny fluid. I replaced my oil seals last summer. I know it definitly tells you the amount in the claymer book. I dont have the exact amount, but I could get that from the book if you need it.

 

yeah if you could let me know what that amount is it would be very help full thanks.

 

Stock had normal air, I believe max pressure is 6psi. The seals will wear out long before the air causes them any problems.

 

ok, Ill check the book tonight. It was like 6oz's one side 8oz the other.....somthing like that, but let me check.

 

best thing I did was put in some progressive springs, that way you can get rid of the entire "air" system altogether.

 

Alright, for your 84 700, right hand fork= 11.9 oz. left hand fork= 12.5 oz. Some Dextron ATF should do the trick. Also, you are going to want 0-6 psi air (use hand pump, not compressed air). Good Luck!

 

thanks for the info you guys are the best

 

The volume measurements are just approximate, what you need to do is measure the oil level. I usually set VF700 forks at 225mm. That distance is measured to the surface of the oil from the top of stanchion tube where the cap threads. Make sure that the spring is REMOVED and the fork is in the fully compressed position. You'll find that the exact amount needed is a lot different than the volume spec. Do not use ATF, get some motorcycle fork oil from your local dealership. 10w works best on unmodified forks.

As for pressure: 1) nitrogen is not used in these forks 2) do not put ANY pressure on them. They work best with no air preload. Adding air causes more problems, if you find that you have trouble with bottoming then you should add more fluid in 25mm increments until it goes away. If you add more than 75mm I'd suggest going with 15w fluid.

I hope this helps!

 

Taken directly from the claymer......

ATF is fine, dont worry. It's just a dampener....

 

yep its not a race bike

 

Go with the 10wt fork oil. ATF is about 7.5 wt or so and I've heard not as good for the seals.

 

ATF is approximately 7.5w - FYI

 

And that's what happens when I go from memeory! I'll change that.

Exactly.
Im sure if it is going to cause damage they wouldn't tell you to put it in. If I where you, I would pick up some progressive springs.....
