What kind of mod did you do to allow the use of gs gauges? I'm hoping to reuse my gauges on my kat f/e and I'm looking for some ideas. The f/e is off a '92 750, and the top triple looks different than some other's I've seen.

Like this one, courtesy of darb



Mine doesn't look like that, it has the clip-ons mounted to the top. But you can't remove them, you what I'm talking about?

Dude this has screws to the lock bracket through the dash top plate and what ever.
Rubber grommet mounts are a must for gauges IMHO, too much delicate sheite to break in the dash assy.
750 kat FE's so beefy, I have heard that if your crash ... it will twist the frame ... that is so stiff compared to the Kat 600 which will prolly break before bending the GS frame.
Cool.

What did you do about gauges?

I dunno ... I sorta look at everything before getting a FE, and werase has that same FE ... I just couldn't deal with the "rig up stuff for gauges" part. IMHO, that FE with all the right mods will make the bike ... or ruin it. I want to do a complete job and be able to can it and sell to people ... atleast partly.
The only thing I can tell you ... a modded Kat600 top plate may be made to work on your stem and FE ... but I dunno till I take it to my (now committed to do this BS work for me machinist).
BTW you weld a GS stem into this thing's lower triple ... you think this top triple will fit it ... I seriously doubt it. That stem will be too short to fit a kat 600 triple I think, cos the kat stem is much longer ... 3/4 inch longer than the gs stem.
A Kat 600 triple, the 750's stem and the triple should be cut to fit it, then we weld ears on the top triple thing and spread the headlight ears etc and you're good to go.
BTW I have a kat 600 triple with a bit of  thread work needed in the ignition thing's bolt. I can mod it if you dont got a 600 triple, but like I said, you have to machine it all in a sequence fitting it on between machining them to make sure what you're doing will work.
Like fit, Measure, cut, fit measure cut, fit ... repeat.
Cool.

I am still in the planning stages on that.Everything is torn down.I'm still looking at purchasing a Kat600 upper and using aftermerket clip ons.I really hate the ditch that my key will be in with the Kat750 upper.

Did you press the gs stem into the kat lower? If so, would the 600 top triple and clamp bolt right up?

Let me set a few things straight here. My statements are based on actually doing the work, not guessing.


The 600 and 750 stems are the same length. The 750 top clamp is thicker but uses a longer bolt. The 600/750 AND the GS stem go into the top clamp the same distance, no matter what top clamp it is.

The GS lower clamp is thicker than either of the Kats. There is about 1/8" of GS stem sticking through the bottom of the Kat lower clamp.

I have already fitted the 750 stem in the GS lower clamp and just needs to be welded.

Pressing a Kat stem deeper to be the same length as a GS stem is not safe in my opinion. There is not enough stem for the lower bearing to seat properly. I would never do it this way for myself or anyone else.

You don't have to tell me that! I trust you and your work 110%

That being said, could I use a 600 top triple and clamp on my set up? Or what would you recommend in terms of gauges?

If you want a 600 top clamp, I will swap for your 750. I do not have the knuckles for the bars so you would need to source 41mm clip ons. I saw some stock 600 clip-ons on ebay for $20.

So the 600 top clamp bolts to the top triple of the 750?

No.
The 600 upper clamp is 1 piece with removable clip-ons, similar to a GSXR.
The 750 is 2-piece with an upper clamp and a handle bar mount that has the attached clip-ons, similar to the 89 GS.

For the record...

1992 GSX600 Steering Stem Part # 51410-19C02

1992 GSX750 Steering Stem Part # 51410-19C02

A lot of my knowledge of part compatibility comes from part fiche research.

I dunno how he is going to do it really ... but ... this is what I ahve found.

It is not hard to do when you actually know what you are doing and talking about.

The katana 600 lower triple is thick, much thicker than the GS triple. So moving the GS triple into the katana triple will leave it too short. The way we did the 600 FE conversion was, to grind out the stem on the bottom and push it into the lower triple and spread it and weld it. We have not touched the GS lower triple at all in 3 conversions.
...

The GS lower clamp is thicker than the Kats.

...
I would take your 750 stem and machine it to fit a 600 top triple. That is where the $50 is going ... to a machinist I enlisted ... 
I measure and mark with the GS and then machine it ... machine it till it cries ...
...

$50 to do nothing??? The stems are the same!!!!

Quote from: The Buddha on April 18, 2008, 12:48:23 PM
...
You really dont want to grind up the lower triple, and you certainly dont want the stem sitting deeper in the lower triple, the stem had to be sticking out of the bottom of the lower triple as you weld it. Then you can shape and grind it. BTW Werase, spread the part of the stem that was sticking under the lower triple, it didn't even need welding, it wasn't going anywhere.
...

A little of the Kat clamp gets ground to remove the stem. There is plenty of GS stem to stick through the Kat lower clamp since the GS lower clamp is thicker. I looked at lowering the stem but there was not enough stem left for the bearing to be seated to properly.

...
Just about the only way to get it all to fit and look and work right, as in ... no spacers anywhere, no funky weird things holding up this or that ... nothing ... machine the stem, mill the kat 6 upper triple, weld ears to the upper triple and slap it back.
...

I did not care for the spacers but it is the easiest way to fit a Kat f/e without any tools. I have written an addendum to include swapping stems.

Quote from: The Buddha on April 18, 2008, 12:48:23 PM

Kat 6 stem is too long, but you rather that than too short. Kat 750 is even longer and that is just more to slice off IMHO. Just measure and mill and cut. Nothing to it. Yea. machine and thread ... oh yea ...
Cool.
Buddha.

The Kat 600 and the 750 stem/lower clamp have the same part number. There is nothing to cut or mill on the stem, except where the GS stem may stick through the Kat lower clamp.


You need to do more research before making such inaccurate statements. It took me about 1 hour to grind out both stems, press them out and fit the GS stem in the Kat clamp. That time also included taking pictures and recording measurements. There was NO machining on the stem. I will have it welded this morning.

will it fit onto my saggy gs without tons of special stuff being machined ? is there a tutorial i missed ?

ohgood... My applogies for the direction your thread has taken.

none needed. information is good, sometimes it's not what you expected, but it's always better to _know_.

PM sent.

This was what I was going to do ... or my machinist is going to do ... For $50 ...
Take the 600 lower triple with the stem, machine the top bearing fit area downward 1 inch, then thread the threads 1 inch lower, then cut out the threaded insert, then cut the stem ~1 inch short at the top, then put the threaded insert into that, weld it and machine that to fit into the kat 600 top triple. He did part of it today, I'll put up pics. You just use that kat 600 stem. I have ground and removed and welded and what not. Werase did it. I like that solution just fine, but guess what, I aint doing that for others, it involves much much more work and expense. The grinding, welding etc and now they dont have the GS stem either so they dont have a running bike when I am working on it ... Bearings - atleast the lowers have to be replaced, and that lower triple is made of some BS casting ... simplest way is to keep the factory stuff intact on the kat, just machine it shorter.
I was not making any statement about the 750 that was specific to the 750 stem ... I was just saying I have a 600 top triple - and I can machine up the 750's stem.
Its $50 for machining the 600 kat stem ... nothing to be done after that but fit the 600 kat's parts on the thing. Till I send it back and you're ready to reassemble ... your bike stays functional with the stock FE. When you swap over .. you have a whole GS FE you can sell to another user. The GS FE is never touched. Sorry ... that is the only method I can sell to people.
Sorry D I came across garbled in that post.
Cool.
Buddha.

How to post pics ... yea I never hosted stuff somewhere and linked here before.
I pulled pics of the thing, including as I was taking it apart to send to average.
Yea anyone else - send me your email and I'll email you.
Cool.
Buddha.
