aacoop,
Here's what i've got:
right side spacer is 24.5mm (brake side)
left side is 13.5mm (sprocket side)
I used the stock GS axle, and the stock adjusters. I think I'll go back to the KZ axle since it has the bolt head instead of the round end...
I think the left spacer is KZ, but the right one is GS (not sure. I just always kept a box of axle spacers on hand, so when I did the swap I had a pretty wide choice. I did want to keep the # of spacers to a min. though.
My shocks are ZRX, also about 14", but I welded tabs for them just a smidgen back to keep the height the same as original. Chain, I just got it a little long so I was sure to get the count right, since the swingarm is a little longer.
sorry this took soooo long!

I wish I could help, but, I divorced my wife and don't have that problem anymore. Just kidding...about the help part. the ex thing is true....

That's a tall order to tune the suspension for both. Been there. Check around the internet for a setof Rear KYB Shocks from a ZRX. Very tunable for early Kawasaki's and a touch taller than stock. Plus, they can be adjusted very easily.
This set is on my GPZ came from a 99 ZRX 1100. I paid about $200 for the pair.

Here are a few more, I guess it will be comin apart again this weekend.
Patton....
The oil cooler is an Earls. The lines are Aeroquip fittings, I forgot where the hose came from, -6AN. The bracket I fabricated from 1/8 aluminum angle top and bottom, and then they simply bolted on, there are tabs on the cooler.
The Devil exhaust is from a Yamaha R1, 98-01 Stainless midpipe. It fit perfectly with very little mods. I fabricated the bracket out of aluminum. The midpipe comes with a pretty think brass or sim gasket that goes between the pipe and the header, which got it close to the header size. I only wrapped the end of the header with about a 1" wide wrap of muffler tape which gave it a nice snug fit once it hardened. The header is a MAC I think, not a Muzzy like in my descrip. So, not sure how the angles would work out with a diff header. I liked the slightly roughed up look of the whole thing once it was on, looked like it had been there a while...
The carbs are stock 26's..they've been great as long as I dont touch them..
I welded the crank over the winter, we have a H2o cooled TIG welder here at work and one of the welders did it for me, took her about a half hour and it was done. made sense to do it since then i would not have to take it apart agin if i go bigger with the displacement.
I welded the frame 20 years ago, and only welded the triple tube and the steering head, which made a HUGE difference when you got on it-straight away. The bike got a little stiffer feeling in the curves though.
Front end is stock except tapered bearings.
and the tag mount was simply aluminum fabricated to bolt on to the encap of the swingarm.
The swingarm is a GS1100 or 1000, not sure. I simply opened up the grommet area to fit the base of the shock and TIG welded opposing brackets for the KAW ZRX shocks. The brackets might be a little overkill, but what the hell..
I have another swingarm if anybody wants it BTW..

Next is a WM6 DID rim and wide tire for the back and a DID rim for the front, swingarm spools installed, and of course trying to figure out this problem wit burning oil...


Thanks all for the great comments..

Best bet to go with the updated swingarm and front forks is to get a complete donor bike. It's the little bits that will drive you nuts and end up past time on the build. Plus for points, the wheels will match, and the suspension/tires size/brakes will do even better together.

Most any bike will do, but the Suzuki GSXR stuff is top notch and plentiful. I personally would go with a ZRX setup for you, it has dual shocks (rare nowdays)so there is a little bit less welding involved. You still will have to become very good friends with a machinist, and feed him $$$ well.

(Interesting note to self: what other modern bikes ran dual shocks, for donor purposes. Hmmm.)

Actually, I would go all out with what you have, and save on the fab. Just pick a way to go with it: cafe, drag race, road race, or wild chopper. Clipons are available for your forks, as are apehangers. Custom seat cowls are relatively easy and cheap to build. Paint jobs can be expensive, but most $$$ is in the prep work. Learn to do prep right, talk to the painter, do what he wants you to do the first time, and money will be well saved.

My build (other than the paint):

Change your headlight (I'd go with a bullet style like on the 82GPZ's), get some drilled discs, ditch the mirrors and the turn signals, install a bar end mirror on your clipons, build some rearsets, build a solo seat and a cowl, ditch the front and rear chrome fenders and measure something up for the front fender (84-85TurboGPZ fender comes to mind). Vance and Hines pipe for looks, Pirelli Sport Demons for the name and the look of the tread, a steering damper and fork brace, and then bracing up the stock arm.

That would be my start for a bike build off. I could have it finished and worked out in half the time of the other way, look alot cooler, and work on the details that make a bike stand out.

Thank you guys,

I haven't joined any club, but my frends have H-D FXR, GPZ900R Ninja, GSX1100S KATANA and so on.
I enjoy riging with them.

Tony, these shocks are for ZRX1100's.
I changed them from Works Performance.
Since mount shaft and hole was compartible with ZRX, no special work was needed.

Thanks.

My 78 can do just over 140 at the end of the straight at Brainard Raceway, but it's a loooong straight ( mile + ???) with an 80 mph running start coming out of turn 10. Bike is 1105cc, with a Kerker and jetting, and some weight loss. Most of the bad handling stories come from the racers that put slicks on and overloaded the chassis. That said I've gone through turns 1 & 2 at BIR at around 125mph (the fast guys on modern bikes do around 150 or 160) with some wallowing. I now have ZRX rear shocks and they seem to have fixed the wallowing. So maybe the stories are from when we didn't have better parts. I have put frame braces on per the old Clymers' Z1-KZ manual. Oh yea, 25 years ago I also put in tappered steering head bearing, the stock balls and races got dented and it drove like it was on BAD rain grooves all the time.

Congrats on finding us! My first word of advice is... research, research, research! (OK, that was three but its really still one word.)

Before I even started buying parts I did searches everywhere to get as much info as possible. I'm even a member on a Suzuki forum (shh! don't tell anyone) because my 1000 and the 900 I'm building have Suzuki suspension parts on them.

Normally the reason that Gsxr parts are used often is they don't require a lot of mods to make them fit and there are A LOT of Gsxr out there from 1986 to present day stuff.

Zrx swingarms are pretty easy to fit, allow some 180 or 190 tire sizes, let you keep the twin shocks and give you the nostalgic Eddie Lawson look.

There are fewer Honda and Yamaha sport bikes than Gsxr and generally you have to do more work to get the parts to fit.

If you have any questions that you can't find answers to after you research, just ask. I'll give you all the info I have or point you in the right direction.

Good luck!

Later, Doug

I mean it handles much better than a stock ZRX

I think you will not have any problems with a high speed wobble.

On many MK2 and ZR1 models the upper mounting position from the shocks was changed (see pic).

Thanks,right now I got the stock zrx shocks on my mkII and it seems a bit tall in the rear,have to wait and see when I get it on the road how it handles if it corners good that's great...don't want a high speed wobble though.Are you running a damper ?

@ zzrmkII

the std. length of the shocks is 365mm.

These shocks were "tuned" by Öhlins,so I have more options for the perfect setting.

The front fork has wilbers springs,thicker oil and less air chamber.

Today I made a little test ride and after some changes at the front and rear it rides perfect.

It handles much better than a ZRX and some other new bikes.
