So I've been thinking lately that when I get around to doing the tear down/restoration on my '78 1K that I would do a front end upgrade. I want to keep the look as close to stock as possible (no USD forks). Options? Yes I tried to do a search but the search feature must be down right now (I kept getting "fatal error" messages).

Here's a '78 with an upgraded front suspension. I have no idea what it is from but I sure would like to know.

Russ..if youn type in TOO many words you get that error message..try shorter key words.
 
Well if you can figure out a way for me to do a search on "GS1000 front end upgrade" in the authorized number of words let me know.
 
If you want it to look stock, get Race Tech emulators, progressive springs and for a smoother ride, use forks from a newer GS, with the teflon inserts to reduce friction.
Finish up with the twin pot Kawasaki brake upgrade and Avon RoadRiders, you will have a decent riding motorcycle.

With some decent rear shocks of course.
 
The mid 90s Katana or Bandit front end will swap - the Bandit needs a shorter triple tree stem (like from a Katana) and has the advantage of having a regular handle bar mount on the top clamp. The Katana has clip onish bars

Find a complete front end so you have better forks, brakes and tire selection

Then an 1100 swing arm, Katana or GSXR wheel and chain conversion
 
I put a '88 gsx600 front end on mine, straight swap, wheel and all. Back wheel just need a spacer.

The Katana front end may be the way to go then. I already have clip-ons. Metmachex swinger, Ikons, Salty Monk brake mod. Going to stay with the Morris mags.

Russ,

The problem with only swapping the forks and triple is that they're much wider spaced to allow for the 17" front wheel

Also, check Katrider.com. Those guys ditch their front ends for GXSR stuff. I got everything in that ad plus the wheel and tire, brakes and rotors for $120 locally

Yeah I have a '92 gsxr front end on my Kat. Just wanted to stay away from USD forks T. I see what you're saying though with the width. SO the trick is finding a newer fork with narrow width. I definitely want to keep the period wheels. Like Tkent said I might end up having to go with racetech emulators. I already have progressive springs in front. Tom what year did they start going with the teflon inserts in the GS forks?

Looking at that first pick he has period rims. I'm guessing the triumph front end is the same width as a GS. All Balls might have the right bearing to do the switch.

I like the sprocket and chain set up a lot better. The bike wheelies much easier. The handling is a little stiffer which is nice, I just don't like how low my bike sits now. It bounces around a lot less now in the corners too which is reassuring.
 
Russ

All you'd need is a custom triple tree set= GS width, larger holes

and probably some adapters at the axle

I would be willing to bet that fork/ front fender combo is off an sv650. Not renowned for their handling prowess, but probably a few steps up from whatever they were doing in '78!

Find a GK triple and forks. 41mm (I'm pretty sure..maybe 40) forks, keep the Morris mags, emulators, spend the big dough on shocks and keep your arm. Get he frame braced. The head stock and through the cross frame especially. Gusset the rear section... Good to go.

Probably WAAAAYY too late to chime in here but that's a VTR1000 set of 41mm front forks with a CBR600F2 front wheel. Uses a VTR triple clamp lower (or was it a CBR600 lower) but the upper triple is custom billet carved up by a friend of a friend in Canada. If I were to do it now, probably look for Katana triple or a Bandit 600 with the VTR forks and figure out a wheel combo from there. Maybe the later SV650 wheels to get that 5 spoke Campagnolo look. Rear on this one is a Metmachex swing-arm and a matching CBR600F2 rear wheel with the sprocket carrier milled down to line up the chain. Chain is a 530 btw.

That is your bike Jim? nice to get the actual specs of the mods done, job well done.
 
I use the 83 1100E fork with an emulator in the 1000 Triples. Works well. You get both compression damping (on the emulator) and the original rebound damping still adjusts. You also get preload.
I have the anti-dive cappped with channels in the caps connecting the ports.
