810cc Wiseco, Garrett GT22 turbo, RC 370cc injectors, lockup clutch and more modern suspension and wheels.

235hp on the dyno (with a boost leak, probably 250hp+ in reality). 30psi boost.

211.0mph timed at RAF Woodbridge in 2006, with a backup run of 210.2mph.

9.29 sec quarter mile with just a change of gearing. 60" wheelbase.

Used pistons bought from a site member. Ebay front end. Honda Hornet 16" front wheel. GSXR600 swingarm etc...

OK, I'm just trying to learn something here. The original 750 Turbo was about 115 hp ( I wish I had mine back now) and the cylinders and head were designed to shed the heat of that much HP. So, how do you keep it from melting down with the heat made from 250 HP and that big ass aftercooler blocking a portion of the cooling airflow?

BTW, fantastic looking and performing bike!!! My Turbo was 100% stock and a blast to ride as it was.

I've done a few bikes, for a "restoration" I:

1) get the thing running and make sure it shifts through the gears
2) tear the bike down, take photos and put small pieces in marked envelopes
3) send out all the hardware for replating, (probably most important step) also buy some spare hardware from the same era (Ebay) so you have extra. The biggest headache is having clean hardware handy.
4) refinish frame and engine. Depending on original condition, replace some gaskets, etc. Easy to do when engine is out.
5) make an initial parts order, stuff like steering/swingarm bearings, fork seals, wheel bearings, spokes, etc.
6) hopefully, by this time the hardware is back. install the engine and main wiring harness.
7) install suspension. rebuild wheels and install.

For the rest of the bike, just work from the inside out. I like to do sections at a time, so rebuild the wheels in one shot, refinish the bodywork at the same time, etc. Then new/refinished parts can go on the bike without the risk of being lost or damaged.

Keep a list handy of some major or discontinued parts you might need, so when you're browsing Ebay you can buy it.

For a restoration, the hardware is key. Nothing worse than a nice shiny bike with rusty ass bolts.

No doubt Joe....

Ok, I'm with Joe, my brain is now toasted!.... :laugh:

Post the project w/images... We're picture whores here!

Welcome to the OBSESSED insanity....

You have me rethinking my thinking here guys, I was looking at the GS1100 swing arm to keep the back looking kinda stock, Lower and longer with vintage wire wheels, but Now I will look into the ZX6R thing. The front end , I can go in any direction at this moment, I want clean and simple, tough and race ready looks. It will all be painted or powder coated. But doing a complete swap might be the ticket...... So please keep talking and I am listening. thank you for you help and useful information .

We're back ! I posted on my first blog about finding information on finding stock or good replacement wire wheel for my KZ1000 (1977) with dual disc. brakes and a single disc brake rear.

Looking for a cool & correct new front forks, with heavy duty triple trees, swap or after market. I like what "Les Holt" posted , that's kinda what I have in mind. BUT ! I still would like to hear what others have done and used, and how they like it.

and lastly is the rear swing arm, I am looking at using the GS1100 swing arm, hows does this work and does anybody know of other swing arms that would work for my application ?

I am building a Cafe' style cruiser, I am planning on cruising mostly, not really going to race it but more cruising around and enjoying the ride. want nice looks and style. Let me know.

Thanks again, if you have any info that could help me, please let me know, Thank you !

Just added the fork before I had to go to work, there isn't any bearings in the head, but it looks very cool. I still need to precisely measure the clearances for the steering stem, hopefully I won't have to swap the stems from the KZ to the ZX14s but only time will tell

Has anyone done this swap before? Any advice would be appreciated.

You are going to need to install the original KZ stem on the ZX14 triple... You can use KZ all Balls bearings... You will need to make a custom upper triple that drops down to grab the top of the forks... See you need to drop the forks down the lower triple to at least the ZX14 position... And if the ZX14 forks are shorter than the KZ forks, there is where you need to drop the forks further down...

As far as the swing arm... This is going to be a real pain... Base you measurements on the Center of the ZX14 rear wheel to the Center of the KZ frame... Then you will need to re build the front end of the ZX14 swing arm to work with the KZ swing arm pivot bolt... This can be a simple as spacers... However you still need to align the ZX14 swing arm...

You need to disassemble the pivot end of the ZX14 swing arm. You should have 1 Left Side inner bearing race/spacer, 1 Left Side bearing, 1 in long Center floating spacer, 1 Right Side bearing and 1 Right Side inner bearing/spacer...

Measure 50 times before you cut... You may need to cut both right, and left side... What ever you cut off on each side, you need to drill in for the Bearing stop... Now, for the 1 Left Side inner bearing race/spacer, 1 in long Center floating spacer, and 1 Right Side inner bearing/spacer... The outside dimensions of your machined spacers will be identical to the ZX14 spacers... The inside should be identical to the inside of the KZ swing arm pivot spacers... Last the End of the Center floating spacer is going to be same as the original ZX14 minus what ever you cut off the sides of the swing arm...

Another piece of advise... Kawasaki is a metric motorcycle... All measurements are metric!!! I suggest not even think of the idea of measuring in inches... Good luck!!!!!!!!! Luis

Hello ! I am new to this blog thing and just got one question in three parts.

First is "What is the best front fork replacement/ swap for a Z-1 "
second is " what rear swingarm fits and will give me three more inches in length."
Third is, I have mags on my bike now, does anybody know where I can find a set of wire wheels for my bike and dual disc brakes on the front from ? wouldn't mind finding an aluminum triple trees for my bike as well.

Please write me back with your info and idea's. thank you again.

Done it three times. First time we used a 17mm drill bit on the frame and GPz750 rear wheel. Second time 84-86 GPz900 spacers and GPz750 pivot bolt with holes in the adjusters enlarged to 20mm. Third time was 84-86 GPz900 spacers with 2000 GSX750 rear wheel (17mm axle). All three times we converted the swing arms to dual shock.

All the shiney stuff is fine and dandy but worthless if it doesn't go down the road.
I suggest you aquire a repair/shop manual and read it.
There are to many 'builds' getting posted on the net showcasing the look but not the function.
A motorcycle is far more fun when it's ridden than posed with.
