R6 Wheels and USD Forks ' 85 FJ 1100 " Upgrade

[Flynt]

stock R1 calipers?

Blue or gold dots are what you want.  You'll need to remove some of the webbing between the caliper mounting bolts to give these calipers clearance, but otherwise they bolt right on.  I did the material removal with a nice set of files...  not difficult at all and, since you only remove that obviously thinner part, you don't see it at all when done.

With that said that's why I didn't think the R6 calipers wouldn't work . So will have to take a look at part #s and see if the R6 and R1 run same calipers ! Seem to find most brands like to run same parts where they can !

Would anyone have a link to a site that has axle sizes ? Trying to figure out if the YZF axle is the same ID of a R1/6 axle or will have to see if I can replace the bearing to get things to fit !
Thanks

That's where it gets tricky.... (IIRC) The YZF750 uses a 17 mm axle, the axle on your R1/6 much larger.

Also, the beauty behind the YZF750/FZR USD swap (using the YZF/FZR front rims) is that they use a mechanical speedometer drive which hooks right up to your FJ's speedo.
You lose that using the R1 rim.

When you get the axle bushings figured out, you will need to figure out a solution for your speedo.

Yea Pat that's sitting in the back of my mind " Do I keep marching on with R wheels or do I stop and go to the GSXR/FZR wheel set up " ? Trying to figure everything out befor I drop tithe money on a R wheel . For the money of just the R wheel I can find both front and back and get what I was after in the first place " a nicer front end and better Performance tires  LOL

I want to see you do this.
Don't stop now, you've got the back figured out, so let's get a matching R-6 rim on the front.
The YZF fork uses a 17 mm axle so you should be able to figure out the bushings needed or perhaps find wheel bearings that will fit the R-6 rim with a ID of 17mm.
(Btw, the axle diameter info. you asked about I saved over in the File section under 'modification')

Frank Moore (racerman 27410) did a bitchen mod on his FJ where he put a digital dash display needed because he also did a front end swap (FZ-1?) where he lost the mechanical drive for his speedometer, so there is a solution.
Tim (axiom-r) did a complete R-1 front end swap, forks and all, and he also lost the mechanical drive. He mentioned a box what could be hooked up with the FJ mechanical speedometer that converts the digital signal from the R-1 rim to a mechanical action which drives the stock FJ speedo.

So....there is a way to do this.  Keep the speedo...or do a digital dash.

I just wanted to give you a heads up, and definitely not to discourage you.  Pat

Pat, one type is made by a company called Dakota Digital.  They have this "Universal Speedometer Signal Interface" that looks it will go from soup to nuts, but it's pricey, ~ $85.  I was telling a friend about this for a Jeep that he's upgraded with a GM transmission.  I'm sure there are others to be found.

I used trail tech vapor on my 86 with 2008 gsxr1000 front. And will be doing the same on my 89 this winter.
The trail tech is digital speedo, bar or digital tach. It has shift lights trip, maintenance reminder, and lots of other stuff I'll never use. I got them off fleabay for $119 apiece.
I kept the stock idiot lights turn signal indicators, low fuel lights ect and put a round digital fuel gauge and voltmeter on either side.
kookaloo sticker above the trail tech. I think it looks pretty good.
I've got a couple of crappy phone pics in my gallery. I can't seem to get them to post. I don't have a working computer right now so I think it's because I'm using my phone. :

Pat, this isn't a cheap solution, but I fitted a Speedhut GPS speedo to my FJ (after spending heaps of hours trying to get my standard inaccurate speedos to work correctly). I managed to fit the speedhut into the same area as my previous speedo, took some doing but it works well (no I don't work for speedhut). No speedo cable required.

No, it certainly isn't cheap

 I did read about a few ideas on the speedo, something called " X connect " or something alike . As for the front wheel itself from what im finding most if not all newer Yam wheels R1/6,FJR,FZ1 all use the same bearing OD (44mm) just change the ID . So now I need to find 17mm ID,44mm OD but not sure on the width of the bearing needed yet ?? Also need to measure the hub and what space between disks to make sure it will slid in with spacers made if needed . But over all its looking better will see how it goes!!

Riding buddy is a Honda guy and was telling me that Honda F2 wheels are 17inch,6 spoke, with a mechanical speedo so that's something to keep in mind !!

Cable X is what you're thinking.....it's more expensive @ $340 than the GPS speedometer Bozo mentioned ($314)
Murphy's Law dictates that as soon as you install the Cable X box and get it calibrated to your FJ, your speedometer clock will start it's inevitable death whine...

I like Bozo's solution the best.
In one fell swoop you do away with the mechanical drive, cable and the old FJ speedo clock which is now on its last legs in many of our bikes.

Bozo, I would like to learn more about your Speed Hut GPS speedometer. It could be a viable option for us.
What size? How is it working for you? Any calibration problems? Did you use the 160mph version and use your oem FJ speedo face? What happens when you drop the GPS signal? Any pictures?

You gotta love this forum.....

The speedo is brilliant, front wheel size doesn't matter, also the Apps for iphones don't update 5 times a second. I am inclined to believe them because even accelerating hard the speedo shows no sign of jumping trying to correct like an iphone. To get a true reading on an APP you have to steady first before reading. Would I buy it again, YES. So far two riders I go out with have fitted these to their KZ900/KZ1000 but they had the Tacho matched and the facias have been tailored.

Pat, I haven't had it drop out yet even around the city, I haven't even noticed it dropping out while going through a tunnel (maybe they have some kind of repeaters??) but maybe I also wasn't paying attention to the speed at the time. I bought the 3.5 inch and because Oz has Kilometers I have 260KPH on mine (you can have any detail you want) plus you can add lettering - "FJ1200" or anything/colour you want. No need to calibrate, it is a GPS with a stepper motor for the dail.
