SanDimas Mike got some recently. Big block like chunks of aluminum. Better to upgrade to 89+ forks, even better to put emulators in them.

Don't the springs fit all years on the FJ? Just different spacer sizes....

I think I heard that you have two new flintlock rifles, or was that you have two new stone axes?  New AD units? Where on this planet did you find NEW ones? Or are they just new to you? Just want to know. You must be holding very true to OEM original.... Them AD units were more hype than useful. Notice how the years after don't have them? If you are sticking to OEM original then Kudos to you. If you have new ones then why block them off? Or are we talking about the forks and not the AD units?  :empathy3:

I noticed how only the 86 and 87 have aluminum gear shift arms and rear brake pedals. Yamaha also did away with the remote preload adjuster. Later fork lowers do not have a drain screw. Swingarms were pressed steel, unvented brake rotors etc. Yamaha was saving a buck. And I agree that the AD units were a period fad....every Japanese manufacture was putting them on bikes.

So, why are we blocking off the anti dive units? Sorry if that's a silly question. hoping the "newbie" label gets me some slack:)

For some it is just removing equipment (the AD units and hoses) that don't not work and reduce un-sprung weight (slight performance increase in suspension reaction). Others do this when they put emulators in to upgrade the forks. I am ditching the 86' forks for 89' forks so I can get a 17" x 3.5" wheel and run modern rubber. This also allows me to put on blue dot calipers with a 14MM master and have better braking as well.

Some members really like keeping their bikes bone stock, or at least making changes that allow easy changes to get it back to stock. Block off plates fit in this category. Bolt them back on and the bike is stock again.

My 90 has the steel rear brake, yes, but definitely a remote adjustment on the shock preload as well as the drain screw.  If that's a steel swingarm, it's stainless, as a magnet doesn't stick to it, also.

Just because it's newer than the 86-87, doesn't mean that it was from the "giving up" era.

Good info thanks.I clearly have a g react deal to learn about FJ,s. I read that these bikes tend to have soft forks. I was going to use a little heavier fork oil for now. My first goal is to get her on the road. Them tweak as I go. Beware of scope creep my grandpa always said,)

That is what I did with my 87 though I use a 5/8" master from old ZX-7 and Speigler full floating rotors. It looks much cleaner than the original forks. I have a set of Brembo calipers sitting on a shelf (I ran a full Brembo set up with the original 16" wheel)...maybe I'll install them. I also have an AP adjustable ratio master on the same shelf but it looks like it will not clear the fairing at full lock. http://www.apracing.com/info/products.asp?product=Pull+Type+Adjustable+Ratio+Master+Cylinders-Variable+Ratio+Type+-+CP4125+Family_2549_1094 (http://www.apracing.com/info/products.asp?product=Pull+Type+Adjustable+Ratio+Master+Cylinders-Variable+Ratio+Type+-+CP4125+Family_2549_1094)   I also have a new 14mm master that I'm going to try this summer.

I wish they were flint locks... then they would be useful
But I do have 2 new ones in the boxes off of ebay
I switched to a FZR front end but seeing that these were as hard to get and as useful as buggy whips I bought them
Pictures coming soon.... yawn

Sooo, for us non-Luddites is there a source for AD block off plates?
Title: Re: anti-dive block off plates
Post by: racerman_27410 on February 13, 2012, 05:10:15 PM
if you remove the tapered spindle (flower pot looking thing) from the bottom of the damper rod then you can just use plain flat plates bolted onto the fork legs with some sealant.

you have to take the forks apart to remove the tapered spindle.


if you dont remove the tapered spindle then you have to use a block off plate that has channels machined in it for the oil to flow out and back into the fork legs.

there used to be someone who made these special plates but its been a long time and i cant find his information.


KOokaloo!

The price sucks and I don't see how the two ports allow fluid to pass. Thus causing hydraulic lock of the forks. The upper and lower ports need to permit fluid to pass freely with the plates in place. If they allow the fluid to pass then I will just settle on the price sucking.

Post by: moparman70 on February 16, 2012, 01:52:17 AM
My guess is the ports don't allow fluid to pass but possibly they go over some protruding metal.  I haven't taken mine off to know but SanDimas Mike would know ....lets get Mikey ...ya lets get Mikey .... he knows everything
Title: Re: anti-dive block off plates

there is no protruding metal at the anti dive mounting location.... just two o -rings

Looking close at those ebay block off plates, looks like they are gun drilled from the bottom and then blocked off - so should pass fork oil and work with no issues.
Title: Re: anti-dive block off plates
Post by: 56 CHEVY on February 17, 2012, 11:00:35 AM
I cuncur with fj1289. There is a hole drilled from the bottom and plugged so the oil will pass through just as the listing says.

One question. If I have installed Race Tech gold valves in the forks in my 86, would the oil still have to pass through? If not, I would think one could just make solid plates to block off the holes.

were the holes in the damper rod drilled out and additional holes drilled above the bottoming cone/ tapered spindle?   if so then you may be able to get by with flat plates.

Ah grasshopper my block offs do not allow fluid to pass. I installed my block offs when I had emulators installed. This mod does require that circuit. Could not find the person that made the plates. He use to participate in this site which is how I found him. He did not charge as much as the eBay option, but the eBay version looks a little better. When time comes to service the shock I will see about getting mine  beautified. I know I know I should get do a whole front end mod.

Yes, the holes in the damper rod were enlarged and the holes added per the instructions from Race Tech. I am a machinist, so I will make my own block off plates. If I don't need an oil passage, flat plates are simpler to make.

read my post left out key word. Should say mod (emulators) does NOT require this fluid circuit.
