Out of curiousity what is a ballpark estimate to do a GS 1100E swingarm conversion on my 77' KZ 1000 LTD? I'm not sure what all it takes to do it.
We were going to get an 81' GS 1100E for parts to support the 80' GS and use the swingarm but it was just oil leaks so now we have 2 GS 1100's but no spare swingarm.

Hi, don't mean to but in here? But I seen key word Katana?! And just this morning, I was looking at an older 91-93 Katana swing arm on ebay.
As I have put together and restored 5 - GS1100 conversion swing arms for Z1-KZ's over the past 10-12 years.
My quick question is: Do you or anyone who reads this know any particulars of the original Katana swingarms? Width? Up at frame mounting
I might just buy it for $30 off of ebay for using parts and welding up something out of it wider and a little longer for a Z1/KZ1000.
As I am also redoing an old school Kosman hub with a double weld rim.
By the way! Nice Work on your 650. Certainly looks like you know what your doing!
Good luck and keep it up!
Thanks for your time.

I know I'm a couple of hours early this month but got a busy day tomorrow. Keeping the "green theme" going this month as we move from South Africa to Sweden for this lovely resto-mod R1 of Anders (purchased in a deal we can only dream of
) so over to Anders:
Honestly, I never thought that I would own a bike again up until eight years ago when I was offered a Gpz750 -82 in a swop for a bottle of whiskey. The guy asked for a bottle of Grants, but that was even to low for me. So for a bottle of Highland Park (approx 40 USD) it was mine.In a pretty sorry state, ran like crap and looked like it spent some serious time in a hen house.
I had a Gpz750 -82 back in the days, racing and road racing, so the idea of resto-modding it, giving it the brakes and the roadholding that I had wished for in the eighties was given. Now eight years later and a stable consisting of four bikes and countless hours spent in the workshop tinkering with them, I am pretty happy that I am back riding. I use all my bikes during the summer months, not only weekend cruising but also riding to and from work on a daily basis. If I’d known then what I know now I would have saved endless hours as I tried quite a few things that didn’t work. But in the end it turned out just as I wanted, I am not looking for a concourse condition. I want it nice, but it should look like it is being used. I still have a few things to do, engine covers needs some new paint, but that will come when I change the clutch. I have a set of newly painted carbs laying around. But with the other four bikes, especially my resto-mod build on a Gpz1100 -84 and an endless stream of friend that needs carbs rebuilt, it constantly gets pushed back .It's an absolute blast to ride, I really wish that I had the 810cc engine that I had in the eighties, that power and the handling this bike has would be the perfect combo.The resto-mod recipe:

gd4now your wish is my command. Have managed to get the exhaust wrapped up this weekend and I couldn't be happier with the end result. I wanted to keep the look of the Harris but repair the damage and maximise the clearance. A big issue for me which was the driver for "tucking it in" as well as the aesthetics was my "little legs" when I am at a standstill my legs are real close to the bike and I didn't want to burn myself when I put my right leg down
Hope "Harris" don't mind me putting their name on it (some of the original is still there !!) The baffle will be wrapped in wadding on final assembly
It looks close but there is 3mm of clearance throughout the swingarm travel

Thanks for the kind words. As for the shocks- I just installed a set of Ikon Basix- chrome bodies with black springs-
A noticeable improvement over the old OEM units and they look good too!

1st?? Is the private messaging system working? Need to chat with MiKaw Matt! About some Chevy small block items! 400CI 4 bolt main cap block with steel heads & matching large harmonic balancer.. And also a set of 90's modern style Aluminum angle plug heads. Machined in for screw in rocker studs. Or anyone else? For Sale!
Hello again. Yes! I know most of the items with date codes! Couple months ago Brad Jr. OINK! Sold an early 72/73 No Date Code Swing Arm on eBay for $236.
He had all the early parts also, Early fork boss's for fender. He had an ugly flaky chrome no shift pattern chain cover. The ad is gone from time constraints.
I Think I have a similar situation? This one I have is pretty crudely built! The production stamping marks on top were the date codes ugly, marks, lines from presses? I don't know?
There is no date code stamping. Also have a no shift pattern sprocket / chain cover. The inner chain oiler pump scored the inside
NOW! needle bearings are pressed in Bronze bushings, the stock steel sleeve bush is too long. it is the one for the 78 KZ1000 that was in with this lot?
The lip on the bronze bush is .164".
I'm wondering if I have to omit the OEM dust cap shields with the O-ring. on each end at the inner sides of frame?
I don't want to start pressing in bushings without knowing the correct geometry of this? Never did this in the past.
I'll post some better pics tomorrow. More pics later.
Just want to know when tha kaw folks started dating the top of swing arm?? Or the worker was new and took a break at the production line?

These are fun bikes to fiddle with because there is considerable room for improvement.
I would not advise porting. A light sanding to remove casting flash and blend in the valve seat is OK but the valves and ports on these engines are already too big for the displacement.
The number one thing I would recommend doing is getting a set of decent 1” over length shocks.
Second is aftermarket fork springs and some type of cartridge emulator.
these two mods make this bike very fun to ride. Very nimble with the rear raised.
take the time to shim the swingarm properly
I would recommend ditching the points for the later electronic ignition, or better yet an aftermarket ignition from power arc. The late model OEM electronic ignition has more initial timing and advance than the points and the Power Arc optical ignition has even more still. Really wakes these engines up. They suffer from poor combustion chamber design so anything there helps.

Hi Kelly!, seeing this is a GS 1100 thread.
I have a Suzuki axle, not sure if it's GS 1100 for the aluminum swinger??
Or a GS 1000??
Would you happen to know? Or have either one to measure? I had a box of Suzuki stuff on eBay for $15 no one bought? It was too heavy? ended ad. Now I can offer single items.
Thanks anyone in advance for your time.
This one is 12-5/8" Long. measured from bottom of bolt head. Just need to know what this fits?
And all those years I re-did GS1100 aluminum swing arms! 5-6 of them. I never saved any info!
Thanks, Marty in Buffalo

Big rubber on that rear wheel. It taxed me a bit getting that up out of the basement and into the garage.
But it slid into place nicely with the oiled axle a nice slip fit through all the components. Nut on the left as per the parts fiche.
I placed a 40 thou shim washer between the inner side of the rear caliper axle boss and the disc side wheel spacer. Nonstandard part, but it put the disc dead nuts center of the caliper slot. See red arrow.
Set the axles mid-groove in the swing arm chain adjustment slots to check for sprocket alignment. My old wooden arrow is not as straight as an arrow, but suggests that the final drive sprockets are in good alignment, which requires some imagination since the engine sprocket is not yet in place. Since the whole steel frame is a "spring", a rip in the lower gears probably elastically pulls things out of alignment a bit. So close enough.
Next might be the rear shocks and get that brake stay on. Basement work bench is getting lighter.

Hi Ronnie V. Here is the swing arm, caliper, a nice set of unscathed foot pegs and nice real OEM Japan shocks that go with this frame deal.
