Hi All
I have been searching for an hour or so , there is a lot of material on here now !!!
My Question is : will the 89 rotors bolt on too a 86 wheel ?
I have blue dot calipers and can get a 89 set of forks . I bought a new tire late summer and want to use that up before I go to 17 " wheel ( other projects going on and budget!!)
In the mean time can I change the lowers to eliminate the antidive put on the 89 rotors to the 16" wheel and use the blue dots and then get a 17" wheel later ?
I saw some pictures of a bike here with the stock wheels and rotors, with upgraded fork lowers and calipers, but the calipers left a ridge of no contact on the rotor from not the right diameter !
Thanks in advance
Bill
I don't remember , it is one of those why do that ?
just do the upgrade and eat the tire.

When I did the upgrade it left me with an Avon front with about 2K left on it. I am glad I did not wait. Get the RPM valves, you will not be sorry....
Bill, we just talked about this.
See the posts on the gsxr1100 rim. George gave us a link where can compare the rotor bolt patterns between different models.
I won't feed you a fish but George has taught us how to fish.... So to speak.
I agree with the others, sell the 16" bias donut and go directly to the 17" rim and modern radial rubber.
Same on the front tire here.. Just time for new shoes and decided to upgrade the rim to 3.5. Although my 3" rim has a fair looking 120/60/17 Dunlop on it..
But to answer your question here are the 86 FJ vs 89 FJ front rotor spec's.

Yes I should do that and then I would want matching rim for the rear (more money )
There is no end in site !!.
I have two other projects on the go also so I was trying to save some money .
I am almost finished restoring a Yamaha TX750 1973
And in first stages of building a vintage style Drag bike based on a 650 Triumph but I'm going to do it Japanese style based on a XS 650 , in the same years as the Triumph !!
Basically to show my friend who is a British bike fan !!!!!!!!!!!!!!!

Thanks for the info that helped me out The tire has only 500 miles on it . but I will keep collecting parts for the conversion !!!
Still getting use to posting if things seem to be out of order !!!!!!!!!!
My 89' came with a 16" front wheel that the PO had installed. I have no idea why. Installing the Blue Dot brake mod was the 1st mod I did. Due to my ignorance at the time, I read that the Blue Dots bolted right on to my forks. It never occured to me that the rotors on the first gen wheel were not the same diameter as what came on the 89' 17" wheels.
The 16" wheel will work with the Blue Dots and 89' forks. As stated in previous posts. Install a 17" wheel. I only had the 16" wheel in use for a month or so. If interested, I do have a 89' 17" wheel that is available.

This is post I was searching for. :wacko3:
I have ´85 FJ1100 and as my rotors are quite worn, thinking about brake upgrade.
To keep my FJ street legal, I have to stay with 16" front wheel.
Do you know if fj1200 front wheel axle is same as on older 1100 and what master cylinder are you using or is possible to use (preferably non urine cup design)?
This seems to me, that to upgrade my bike, I just need ´89 FJ1200 forks, blue dot calippers and it is bolt on?
Thanks
Stepan
Stepan, all years of FJ have the same axel diameters. But the '89+ front wheel is 17 inch. If you are limited to only 16 inch front wheel size then you could get adapter plates that allow the Blue/Gold dot calipers to bolt on. There are a few options for the master cylinder. I am using a 14MM MC from a Kawi Concours and it looks similar to the Yamaha unit. It also fits an adjustable lever if you want that option as well. I used my Yamaha master for a while so keeping the MC might be an option as well.
Thx FJmonkey,
http://www.fjowners.com/index.php?topic=9954.0 (http://www.fjowners.com/index.php?topic=9954.0)
In this thread it seems, that axels are not interchangeable.
And yes, I´ll keep 16" front, I like that design anyway, I had same wheels in 18" on my previous bike XJ600(aka FJ600 in US).
Adapter plates won´t work for me, because it is more weight and have to buy blind plates to cut off anti dive units anyway.
I still have stock ´85 1100, only KVT-sport aftermarket foot pegs and lowered seat installed by PO, I added SS braided lines on the front and self made rear seat cover.
I bought it 12yrs ago and since then, beside I love this bike, somehow it turned from old crap to a nice youngtimer.
Upgrading to later FJ forks is IMHO better option for similar price.
Great is that I can keep original MC at least for now.
Just double checking that I can fit 16" wheel into ´89 forks, does not matter on which axle, before spending money on parts.
As FJ1100 have double vented rotors, it is hard to find replacement and for price of original ones I am planing this upgrade.
The 1989 rotors will not bolt to your OEM 16" front wheel. Here is a set of new aftermarket rotors that will fit your OEM 16" wheel. http://www.ebay.de/itm/Yamaha-Fj-1100-Front-Brake-Rotor-Disc-Pro-Factory-Braking-1983-1987-2-Rotors-/381690052269?hash=item58de7ffead:g:~RoAAOSwEjFXd~vs (http://www.ebay.de/itm/Yamaha-Fj-1100-Front-Brake-Rotor-Disc-Pro-Factory-Braking-1983-1987-2-Rotors-/381690052269?hash=item58de7ffead:g:~RoAAOSwEjFXd~vs)
For the Blue Dot calipers, here is a link for the adaptors that make everything bolt on. http://www.exactrep.com/acatalog/Front-Hanger-Brackets--pair--12B.html#SID=22 (http://www.exactrep.com/acatalog/Front-Hanger-Brackets--pair--12B.html#SID=22) Yes, these are for a Vmax, but they will work on the FJ1100 forks.
Fred
You don't need blank/blocking plates for the AD units. You can remove the upper half and flip the lower half. Not as clean as the 89+ forks but less cost. Just so you know what your options are.

On my '84 I have RPM suspension front and rear, Braking Rotors front and rear, and EBC HH pads front with organics rear. I run the Avon tires and give them excellent reviews. For me they're 1 finger brakes and modulate really well. The rear is a little too strong, but useable... probably about perfect if you
want to back-in, cause it's sure easy when you don't want to. Randy tells me I'll overheat this setup eventually, but it is very solid and well behaved IMHO. It helps that I'm slow.
I'll likely go to 17" at some point to get the tire selection, but then you do need all the other stuff to be road worthy with that level of grip. You don't need to jump to that immediately, you can stretch the 16's pretty far... again IMHO.
Frank
I can NOT do 17" front due to local law. So I have to stay with 16".
I do not like those V-max adaptors, it is just aesthetic opinion, unsprung weight, they are for bigger discs and for same price I can have ´89 FJ1200 forks.
If triple tree is same, I can fit forks directly. From picture posted by aviationfred I assume that is no problem to fit 16" rim but don´t know if I´ll need spacers or different axle.
FZ1 2006+ silver dot calipers are likely identical to R1/R6 blue/gold dots (aesthetic again) and if i can keep current MC, only new 282mm rotors needed.
Is this correct, any issues?
Thank you
The 89 forks will fit the triple tree, the 86 wheel will fit on the 89 forks. the caliper position on the 89 forks is for a larger rotor so the calipers will not properly engage the rotors. But this too can be adapted at the cost of cosmetics and un-sprung weight. It is a shame you can't use the 89 front wheel, it is a standard FJ part, just not for the 84 to 86 (87) years. But we also understand some countries have strict rules on vehicles that prevent modification, even if that modification improves the vehicle or makes it safer. If you install the RPM fork valves you could have the AD holes welded up. That would be a huge improvement in front end handling and a smoother ride.

Frank, you might be able to sneak this past one of the new guys, but not us Regulars. :drinks:
Fred, it looks like you used the '89 forks and blue spots *without* adapters on the smaller dia.'84/87 rotors and 16" wheel.
Am I seeing this correctly? Did you have proper pad/rotor coverage with this set up?
If so...Bezmozek would not need the adapters. He would just need the '89 forks and axle....and blue/silver/gold axial monoblocks.
The eBay link to some (narrower) single faced rotors will help vs. the wider oem double faced (vented) rotors.
Again, but it looks like the 298mm vs 282mm diameter rotor difference is not an issue.
Bezmozek: To get the best out of the monoblock calipers, I suggest replacing the oem 5/8" master cylinder with a 14mm master. I use the 2002 FZ-1 although several other models can work...the key is the 14mm piston.

This picture is why I was asking about changing calipers & fork only, just don't like quotations with pictures :sorry:
In adapters description it says that 298mm rotors needed, so same as with 89+ fork instead.
As I have to buy new rotors anyway, there was I think possibility to buy 300mm rotors for V-max, if those 2mm fit in calipers and those should be bolt on :scratch_one-s_head:

Somewhere here was link to a list where was possible to search rotors by diameters, BDC etc. but I can't find it again. :dash2:

The '89 that I ride today is the same one that came with the 16" wheels when I purchased it. The following photos show the '84-'86 wheels and rotors with the OEM '89 brake calipers. I will say that the axle, speedo drive and right side spacer were OEM for the '89 and will work with the 16" wheel. It was over 5 years ago and I can't remember looking to see how well the OEM brake pads or the blue dot brake pads contacted the vented rotors.
Fred
Yup! Not slow. Nice try! :good:
Thank you everybody for info and patience with newbie.
Google says that I need XVS 650 Drag star rotors for perfect fit

I will let you know.
Thanks again
I would look for semi-floating or floating rotors.
Reason: The FJ is a heavy bike. The 15mm front axle (small by today's standards) deflects under load. When the axle deflects, the wheel and rotors deflect. The axial mounted brake calipers and pads do not deflect. See the conflict?
A semi/full floating rotor will allow for this deflection. A rigid mounted rotor, not so much.
Just my opinion.
On my 84 I have fitted 89 forks and calipers. All I needed then was to fit early Vmax discs. No adapters required.

Pat, wouldn't deflecting rotors push the pads back?
Noel
Yep, but not evenly. You could experience uneven tapering pad wear.
The primary reason for floating/semi floating rotors is to allow for expansion/contraction.
Most, if not all rear brakes use fixed rotors, not so on the front.
2 krusty: What diameter of rotors are those?
I figured out, that possible issue can be fitting blue dots inside 16" rim as gap between rim and 282mm disc is tight already and if I increase to 298mm, not sure if there will be enough space.
As blue dots are way bigger than OEM, I am thinking about switch to FJ1200 calipers instead.
Other way is to bolt on rotors to rim with calipers on already, but quite complicated for later service :nea:
Edit:// BTW: Does anybody here know weight difference between 1100/1200/blue dot calipers?

No such animal as 1100/1200 blue dot calipers.
The Yamaha monoblock calipers come in 3 colors, blue, silver and gold and they come from different models, like the 600/750/1000YZF R, the FZ-1 and the FJR to name just a few.
The gold monoblock calipers are the lightest as they use aluminum pistons. The others use stainless steel pistons. We are talking a few grams difference....nothing of significance on a street bike.
We always say 'blue dot calipers' here on the forum when we really should say 'axial monoblock calipers'.
They can be any of the three colors and work the same.
Thanks, that is not a big issue, just somebody here mentioned, that monoblocks are lightest. As it is not significant difference, I don't care about few grams.
Gold dots are really huge and I am afraid there will be not enough space between 16" rim and 298mm rotors
(16"x2,54-29,8)/2 makes 5,42cm to sneak caliper into its place
I am starting to think about Triumph 4pots, these are bolt on to my current fork and hopefully it will be better even with current MC,
just hard to find here pair for sale.
Pic. from RD350, but bolt pattern is same 83/84mm.
