Thanks Leon.
I still need you to make another set of swingarm bushings for me (mock up bushings installed now) and weld up my upper tree for riser support, so I can mount a set of motocross style handlebars.

P.S. I looked at the seedo cable on this 1995 GSXR front end. It looks like it would hook right up to my KZ dash???
If so I want to mock up the dash and have a mount welded to the top tree also.

I have always been annoyed at the quality of the swingarm mods and that the pivot bolt is exceptionally tight. So taking it all apart has revealed that the ape who set it up for me has in fact just fitted some massive brass reducer sleeves to run directly on the pivot bolt - no bearings AT ALL.

It's with a top notch machinist now who is quoting £400 min to bore and fit a new sleeve with a proper set of bearings and a titanium pivot bolt - apparently the whole pivot area has been gorilla'ed and needs some serious reworking.

So I'm now 99% certain I'm going for a custom swingarm. Have pretty much settled on a metmachex - metmachex.net/swingarms/ a clean chunky box section, unbraced and with twin shock mounts obviously.

What should I consider in terms of mods regarding length and shock placement etc.

Thanks for hanging in there peeps - I know this must be getting boring...!

sounds like the same machinist that did that hideous first rear brake caliper hanger, or not?

in both cases: what a twat.

i agree that there are plenty of stock kawasaki arms that look a million dollar... the 1100/1220 ZRX comes to mind, is twin shock ready and has the trademark kawi eccentric chain adjuster. easy to attach shock mounts to a 83-85 gpz750 arm too. dont ask me why, but those arms have "the kawasaki look" for some reason, metmachex always looked to me a bit tacky and overdone.
would stick with stockish lengths for arm and shock mounts positions.

but make sure someone who knows what he's doing adapts it to your frame and wheel. centering the wheel on a new arm requires with bushes some knowledge.

Sounds great! I know you've had some tough times and some doubt throughout this build but man is it paying off! The bike looks killer!

I clicked on m video to make sure the right link was in place, played it and another video popped up of a guy starting his bike for the first time in 20something years. he was thanking Mark1122, and a couple other guys from this forum, what a small world.

I have one hot lead that may have been contacting bare metal on acceleration. The headlight is on its way, then the taillight, a horn and signals. At that time I will be trying to locate the short, unless of course connecting all the hot leads removes the problem.

my dad is currently painting one for his kz650 :laugh: .
they are alot like the gpz fairings.

but,
that airtech fairing you linked to is a really cool fairing and would look right at home on your bike(or any kz).
can't go wrong either way.

leon

Thanks Leon! That is the one and it is cheaper. They also have a nice chin scoop I like. Thanks again for the link.
Hey Leon are you a CNC machinest? I need to make a caliper stay for my rear caliper. My year of caliper does not match my swing arm. All it needs is a block of aluminum with a grove cut in the center for the caliper to slide into. the block will be welded to the inside of the swing arm.

If anyone else has a solution to this please let me know.

If the existing sprockets aren't worn, but the chain's o'rings have deteriorated, seems reasonable to replace the chain, and use the existing sprockets.
But 10,400 miles may be reason enough to replace at least the rear sprocket.
Perhaps the rear sprocket pictured doesn't actually have 10,400 miles on it.
The front sprocket is often more durable than the rear, but it's relatively inexpensive.

Some factory drive chains were endless design (without a link), whereby installation entailed removal of the swing-arm.
Am thinking this idea began with the Z1.
The factory endless chains did not have o'rings, at least on the Z1.
Am uncertain whether endless 630 chains evolved to o'ring styles. :unsure:

Meanwhile, the aftermarket link designs became popular due to easier installation (and often less cost) and have been reliable where the master link (and clip, where applicable) are correctly installed.

Good Fortune! :)
