Tried and True Swingarm Swaps

No eBay APP ID and/or Cert ID defined in Kunena configurationyou need to find out how wide the zx14 arm is at the pivot.
most kz 1000's are 9.250 inches inside the frame rails where the pivot fits.
i've modded a couple of these

for kz1000 use and they will hold a zx14 wheel width wise..
might have to weld a tab on for the brake.
the pivot takes some pretty extensive mods to fit in the kz tho.

Yamaha XJR1300 is currently my favourite arm of choice at the moment as they resemble the old JMC's.
Must have done 10 or more.
11mm off each side and they slip in square. Just have to sort out the 4mm pivot difference.
Most modern big kwak arms don't give much room to shave the pivot before you hit the spars and they can also hit the rear frame uprights close to the pivot.

My latest Turbo build getting the XJR arm treatment.
Stock rear brake pivot had to go and rear footrest mounts too.

What is the length of this arm compared to a stock arm ???

Dave

that looks pretty close to the fz1 arm i posted.
a nice under brace and they would look like the arms sanctuary uses.
i've saved one of these back for myself.:whistle:
here is how i addressed the pivot bolt difference.



i don't guess we got the xjr 1300 over here.
i looked and looked for the front end off one.no luck

I think it's around 3 inches.

Heres a GSXR600 arm on my KZ1000 CSR. I had a set of cleats made up and welded on the arm to keep the twin-shock set up. There was quite a difference in the pivot tube diameters so theres an insert in the swingerarm pivot to accept the original Z pivot pin. I cant remember if any spacers were needed (its been a while) but definately didnt need anything taken off at the pivot.
The rear footrest hangers had to go and I even had to grind a bit off the sides of the swingarm where it entered the frame, to stop it binding when the shocks compress and the arm lifts.
I also did something with the rubber chain protector as it didnt line up with the chain run but again,I cant remember exactly. (its all in the build thread).
Satin black powder coat and some stickers finished it all off nicely.

Kawasaki 636 , close to perfect fit.
Kawasaki zx7 does not fit. Too bad too it's a good looking beefier swingarm.

I am a little undecided if i go mono or twin shock this seasson!?!? Any suggestions???

twin shock just looks right on these old bikes.

Thank´s DoctoRot, so i will go the ZX1100 (GPZ1100 UT) engine and EFI swap first this season. All needed parts are ready to go.

Very interested in your efi swap. Keep us in the loop.
