Hi, this is my first post. I have just bought a scruffy non-running Z900 which I intent to restore/upgrade and put back on the road. I will post a picture when/if I can work out how to do it. The bike is a 1976 Z900 A4 which has been imported from California. I bought it off ebay and it will need quite a lot of work. The bike is mostly complete but has non-standard exhaust, wheels and seat. The engine turns over with the kick start but the bike will need a complete rebuild. I thought it was reasonable value at £2000 but ask me again when I have bought all the bits I need!

I have been spending more time than is healthy on the Japanese Sacntuary website. My initial plan was buy a complete sanctuary bike and import it to the UK. A Japanese colleague contacted sanctuary for me and was quoted €40,000. I didn't bother to ask about shipping.

Plan B is to buy a scruffy bike and do my own Sanctuary. I want the bike to look as standard as possible but with modern suspension, wheels, tyres and brakes. I will try and track down some RWU Ohlins forks and will source a new swingarm from Japan. I would appreciate some advice on rear tyre size. It seems that it will be much easier to accommodate a 160 than a 180. Any comments or suggestions would be appreciated.

The pipe is a Kerker. It is in reasonable condition, no obvious damage but needs stripping and repainting. Haven't decided whether to keep it or not yet. Will PM you if I decide to sell.

A 180 tyre/wheel is not to difficult to fit. You will need a 5/8" offset front sprocket available off the shelf from Debben, or made to order by Talon. Then you'll need to machine something like 8mm from your sprocket carrier (depending on what you use).

If you're using later Suzook wheels (Bandit 1200, GSXR, etc) then I believe the early EFE sprocket carrier fits straight on, and is not so wide (less off-set) :wink:

This is my 'new' bike. Having owned it for all of 5 days now, there are some interesting features (other than the fact that it doesn't run). Some previous owner has spent money upgrading it. It has:
2 front discs (1 was std in the US)
Kerker exhaust and K&N filters
Unidentified alloy wheels
Somewhat crude rear disc conversion
What looks like an aftermarket oil cooler
Finned engine side covers
....and an engine with no serial number. I guess the crankcase has been replaced at some stage. I have no idea what's inside, and probably won't get time to dismantle it until next year.
I am going to focus on the frame and suspension first. Have looked into Japanese swingarms but 1) horrifically expensive and 2) no chain guard mounting. I think I will buy a Kipkawa S1 arm instead.
Still trying to get a price for Ohlins forks but Harris have suggested XR69 replica forks with Ohlins internals, which will look more original.

No pictures but I thought I'd give you an update on where I've got to. I have been busy sorting out the design of the front end. After much research, I have ordered a pair of Ohlins RWU forks and sanctuary/sculpture yokes, both in black. These should arrive in March, I hope. The plan is to fit a 17" front wheel and this has made things a bit more complicated. The forks need to be longer and the steering offset needs to be reduced to compensate for the smaller wheel.

Ohlins don't actually list forks for the Z1/Z900, but the closest fit turned out to be a H**** CB1300. I presume the Sculpture yokes are specially designed for 17" wheels because they have a 40mm offset versus the standard 60mm. This means that the trail will increase by about 8mm, which will in theory make the bike slightly more stable. The heavier steering will I hope be offset by reduced gyroscopic inertia from light wheels, brakes etc. I'll fit non-radial brakes but haven't decided which brand yet.

There's a Kipkawa swingarm also due in March and the plan is to order some Nitron shocks when the the chassis is sorted.

Will post some pics when the bits arive.

Recon I need to camp outside your place & mug the Postman.

They all sound like my dream bits...wheras I have to spend ages working out what kawasaki bits will fit.

Still, where's that couple who won the Euro lottery....maybe I could become his personal groomer and cut his goatee beard for £600 quid a shot...Just like The Beckhams.
