i've got some questions,but i am not sure where to start .

thanks for the post.awesome work as usual.

keep us posted,

Thanks, Will try my best.
Have had a lot of problems posting pictures on here and gave up for a while but now everything seems ok so i pasted everything over from my thread on the Z1OC site and it's all up to date now.
The valve stem heights were actually done this morning.

in this picture here,




the adjustment idler is the kz650 right ?
what is the heat affected zone,did you have to weld on it?

the top idler on the right what did it come from?

did you re-use the needle bearings or source new ones?

i have some gsxr forks that look like your zx-10 forks,any idea if the same trick could be used on the gsxr forks to extend them?

you are very glad that i do not live near you ,i believe you would grow tired of seeing my mug very quickly.

otoh,i could watch you and you wouldn't have to answer so many questions .

thanks in advance for any of the darkness you can clear from my mind .

you are going to have quite the collection of hand built brutal zeds in the garage.

Truly one of the best builds on KZR glad to see you are back at it, alot of info and great ideas thanks for posting.

Ok.
Yes!

1. The middle one is Z650 and on the other side is a slim threaded insert i brazed in to take a bolt (which explains the blueing) so that it can be dismantled easily (A button head bolt will replace the caphead when it is actually fitted)
There is also some subtle trimming of the bracket to be done before fitment which i will post details of once the head is complete.

2. Right top idler is 78 Z1R or z1000A i think, I've had some that are riveted and some that have the bolt.

3. I have fitted new bearings. I was suprised to see that Kawasaki used an imperial bearing amongst all the metric.
It's 7/16 x 5/8 x 1/2 inch.

4. Any forks can be extended to some degree by this method.
The amount of length gained will be governed by the position of the top bush AND the amount of give on the rebound spring which i didn't mention in my posting.

Hope this helps

yessir,
i appreciate your taking the time to answer my questions.
thanks zed,keep up the good work.

Very detailed, I love it. Very trick ignition, can't wait to see it come together.

Great job. i love the way u extended the fork length.
Well done.

Building this motor on a budget and just using up stuff i have lurking about so the inlet valves are std and have been trimmed along with the retainers etc to get max shim sizes back.
Plenty of graphogen on the buckets and valve lapping sucker is ideal for working it round the bores to get an even coating.



The std exhaust valves were quite battered and after recutting the seats and heads were borderline for trimming the retainers so a cunning plan was executed.
I had some 1mm oversize stainless valves from a customers bike that had very slightly wonky heads after his local bike shop ballsed up his engine rebuild.
So i chucked them up in the lathe and viola ! one set of std size stainless exhaust valves.

The head is now finished and bench shimmed so on with finishing the idler gears so i can fit it.
Sourced new roller bearings for the idler wheels i modified earlier.
simplybearings.co.uk/shop/p92295/BA78ZOH...ch/product_info.html
Strange how kawasaki opted for these in imperial when everything else is metric ?


Then on to my skinflint approach to a liska tensioner.
Left one is std z9/1000.
Middle is Z650 which has a bigger wheel . The black areas need removing to clear the barrel casting etc.
and right is modded Z650 item with idler sprocket.

zed,
on your rebuilt sprockets is it a solid alu.center or is there a steel bush in the center for the bearing bore?
in the pictures it looks like there is a steel center bush,maybe just a cutting oil stain .

i love your no holds barred method of bike building .

guide sprocket rubbers worn out,
no sweat just rebuild them with aluminum.

exhaust valves un-usable,
no sweat just cut down some intakes.

never say die man .

and a big up yours to anyone that didn't think you could .

keep up the good work sir.

Hi, Well spotted.
Yes the center is steel.
It's the original idlers center with the bonded rubber removed.
I was gonna just bore the ally for the bearing but decided thet the steel would be less prone to wear during future bearing repacements.
Maybe a bit overkill but i don't like doing things twice.
