Rear Wheel Question....Will it fit?

[Pat Conlon]

...I have an FZR600R wheel and brakes and the caliper clamps firmly between the hub and the swing arm....

"Firmly" eh?  It just surprised me that you think so....just caught me off guard.

Terminology aside, it is interesting that Yamaha refers to the caliper stay arm as a "tension bar" when actually it works under compression.

Arnie,
You are correct about the forks being 43mm..... I looked it up a couple of days ago. You still wouldn't get the chicks, through

Joe

Hmmmm, IF the forks are 43mm, then you can either mill the FJ triples 1mm larger to accomodate them OR see if you can fit the Suzuki steering stem to the FJ and not only get stronger and better controlled forks, but also be able to fit your choice of 'standard' bars.

As for getting the girls....
I've never relied on forks to determine my desirability :-)
Some who do need that attractant say that upside downs are the way to go.
My wife definitely prefers the FJ to my other bike which does have upside down forks.

You would have to check the distance between the forks and the offset for them to work in the FJ triples.

That's where the early FZ1 cartridge forks work so easily...... offset and distance is the same as the FJ...... you just have to bore the top, bottom and handlebars to 43mm and its all bolt on.

I think the whole idea of milling the triples is not the way to go. I like the idea of using the triple clamps that were designed for use with the forks. Almost all of the more modern bikes use a stem at the center of their triple clamp that is larger diameter and longer than our FJ units.  So the FJ stock stem needs to be fatter to press fit into a newer lower triple clamp and longer because more modern triple clamps are thicker.  The FJ stem is steel and is hollow and it readily accepts a press in extension that can then be turned down to the proper diameter for the newer lower triple. Welding the extension to the stock stem before trimming it is the way to go.  ALL BALLS makes conversion easy - you can tell them what bike the front end came off of and what bike its going on to and they will send you bearings that fit.

Putting the FJ steering stem into any more modern triple clamp and fork set up means you get better parts on your bike vs. the alternative of using your stock triples with material removed which is inherently weaker...  

All that said - cash is king.  Do what you gotta do to get the better wheels on your bike Joe.  You will love them!

Just out of interest, I put a complete 99 model R6 43mm front end on my 92 FJ12. The R6 stem is the same diameter as the FJ but alloy, as compared to FJ steel item and is shorter. Same bottom stem bearing but R6 top bearing is smaller.

I had to swap FJ stem into R6 lower triples (pressed in with circlips) and machine a top hat bush to fit under the top triple. I also drilled and threaded a 6mm screw through the lower clamp into the stem to prevent any turning of the stem.

The worst part of the conversion ? fitting the ignition switch onto the R6 top clamp.

Yes, firmly.

The terminology Yamaha uses may be interesting but it's not surprising. I have not read the FJ manual but I imagine it is much the same as most others, odd terms, making simple jobs difficult, errors and terrible photos.

Personally if it was me I would have got the whole parts bike an fired up 're torches and welder.
