Not having much luck with this in the tech forum, figured I'd try it here:

Got this nifty swingarm in a multi-directional swap deal. I basically traded an old Evinrude outboard engine that I found in the alley for this. Any ideas on manufacturer?

~~Pretty sure that is an early model version made by OVERracing Japan.~~

Toxic is correct in the other thread. It is a Cal-Fab.

It does look a bit like a Susuki arm..GS 1000 or 1100 ?

BLUE71TURBO · « **Reply #3 on:** April 21, 2012, 09:35:51 AM »

That swingarm is made by " CAL-FAB " of California, which is no longer in buisness.

A stock Suzuki arm has extra bracing across the backside of the box section. Also it has a large " X " on top of the box section.

Better yet, i found a pic of a GS 1100 arm.........

How much longer than a stock Honda arm is that gs arm Jon.?

BLUE71TURBO · « **Reply #5 on:** April 21, 2012, 07:34:31 PM »

Retro, I don't have a clue.

I guess i could do a search and find out. I know it's a nice fit for the early Kawi's 73-80.

BLUE71TURBO · « **Reply #6 on:** April 21, 2012, 07:56:58 PM »

Well i found out that the stock GS1100 swingarm is 1 1/2 inches longer than a stock KZ900-KZ1000 swingarm. So what is the lenght of a Kawi swingarm ?

Hell i don't know.

Another search comming on............

BLUE71TURBO · « **Reply #7 on:** April 21, 2012, 08:08:47 PM »

Ok, i found a post that stated that a stock KZ1000 swingarm is 20 1/4 inches from the center pivot axle to the center of the rear axle mount. Don't hold me to this as this is second hand info. So that would make the GS1100 aluminum arm lenght 21 3/4 inches in lenght.

754 · « **Reply #8 on:** April 21, 2012, 09:14:51 PM »

I think the Suzi is about 2 inches longer than CB 750

voxonda · « **Reply #9 on:** April 22, 2012, 02:51:09 AM »

Suz GSX1100 swing is as long as F2 swing.

Nice detective work Jon...

Thanks Frank and Rob....

Was it a direct bolt in Rob.?

I have a couple of stock GS swingarms I can sell if anyone is interested

754 · « **Reply #12 on:** April 22, 2012, 08:48:07 AM »

As far as I know the GS swingarms use a bigger diameter on thr pivot bolt, so you have to sleeve down, or accurately drill your frame..

MRieck · « **Reply #13 on:** April 22, 2012, 08:58:27 AM »

I think it is one of the "stolen" JMC swingarms.

Must be worth a fortune if it is, getting your hands on any JMC swingarm is a miracle.

The GS swingarms use the same size pivot through bolt as the 1973-1980 KZ900-KZ1000's which is 20mm.

Note; That is the diameter of the bolt ( 20mm ) as for length..... I don't have a clue.

YOU LOOK IT UP !

BLUE71TURBO · « **Reply #19 on:** April 24, 2012, 09:08:32 PM »

Bert, what are ya looking for ? A chain guard or chain guide ? Or both ? I don't remember the gs1100's having a chain guide but i could be wrong.......maybe.

LOL ! Look it up on ebay and see if there's anything like that.

Ok Bert, here's a couple of chain guards on ebay........ http://motors.shop.ebay.com/i.html?_nkw=gs1100+chain+guard+&_cqr=true&_nkwusc=gs1100+chain+gard&_sop=10&_rdc=1

You might try CRAIGSLIST or some local motorcycle salvage yards.

As for a guide, they do not exist.

You could always make your own.

Hey RR,

Just some minor 'fiddling' with the width of the pivot and to make it accept the pivotbolt. At the lower shock mounts it is as wide as the F2. For making it work in a K frame you need to alter the upper shock mounts Take'm outwards.
Also the depth of the swing is based on a 17" rear, so a 18" will touch the swing when in max front position of chainadjustment.

Cheers, Rob

Thanks Bert,

I checked with a rear wheel with (new) Dunlop TT100. It just didn't touch. Looking at your pic there is enough space.

Cheers, rob
