What to do first?

[FJmonkey]

Hi again.
After doing some research i have found several forks to a reasonable price.
Those i have fitted are stock 41mm with antidive.

So, the question is wether to change to newer 43mm from 91, also think this means i have to change the mounting brackets for the fork, am i correct? Does the wheel need to be changed to?

Al sow got a good price on a fork foam an FZR1000, but i am more unfamiliar with this on, but i am guessing brackets would need to be changed to?

There is always the option to keep stock, and mood with RPM parts. But i gone take the whole thing out anyway, so i might just change it..

I would apricot some feedback from others that have experience with the forks mentioned above.

Cheers

Ken

Forks from an FZR1000 may be an improvement from the 86 forks but the RPM valves will not likely fit. The valve is sized to fit the specific ID of the FJ forks (thanks Randy for that info). So if you want the modern suspension improvement from RPM you will want to stick with FJ parts. However others have put on YZF (and similar) USD forks. They look really good. Not sure about the cost or effort.

First of, sorry for all the misspellings in my last post. Not the same typing on an iPad   

I do think i will stick with the stock fork, and use the parts from RPM to upgrade it.
Putting on YZF forks will be a lot more work then improving the stock, and more expensive at the end so don't think it's worth it.
The previous owner did modify the forks some i found out recently. Don't know what exactly, but he fork has been hightend a bit for a higher riding position, or so he told me.

The RPM fork valves, were exactly are the mounted on fork?

Disregard the question regarding the fork valves.
Jut saw another post about it, and explained it very well

1991 FJ 

My memory may be hazy, but IIRC, all the FJs came with 41mm forks.

Someone please correct me if I am mistaken.

To bee honest, Im really not sure actually. While searching for forks without antidive, a local dealer of used MC parts told me those forks with the antidive valve came with 41mm forks, later model without A/D came with 43mm...
If all FJ came with 41mm i would be happy, since that would make it easier for me

The 89' forks I put on my 86' fit the RPM valve and they don't have the AD units. I think the answer is all years of FJs have the same diameter fork tubes.

Correct!

If that's the case, it should be an easy job then, replacing the forks and "escape" the Anti Dive
Not to mention a better look for the new brake lines 
Thanks a lot!

'89+ FJ forks are still 41mm.  They will allow you to change to an '88 FZR1000 wheel, 298 mm rotors and blue spot calipers.  You will be able to keep your existing triple clamps, speedo drive, axle, spacer and fender.  These forks will fit the RPM valves.

Add some braided stainless brake lines and you have one hell of an upgrade!

This just saved my winter
But i still can't figure out why the dealer meant the forks were 43mm, and the need of brackets replacement etc to be able to fit the new fork... Strange..

How supplies the blue spot calipers bybhe way?

Sorry all the miss spelling, damn ipad...

Cheers.

No disrespect meant to any particular dealer, but this collective, as a whole, knows more about FJs than many dealers did when they were new.

Locally, I'm fortunate to have a very good one.

Add in the time factor, plus the fact that many dealers employ many people who are younger than than the bike is ("What's an FJ?  Who makes it?"), then figure that a lot of those can't even look up parts, and you can see how answers like that come about.

Thank God for FJOwners.com!

[Mike Ramos]

Right on the mark Leon.

Thank our lucky stars for Marsh & FJOwners.com and Randy from R.P.M....!

Perhaps two of the most important people who make the pleasure of owning & maintaining FJ's just that, a pleasure.

Thanks again,

Mike Ramos.

blue spots are off early yamaha r1, r6 , xjr , fjr ? fz1 ect, eBay is a good source , just don't buy the radial ones they won't bolt on to your standard forks
