Hi Kenny,

as I have both kinds of Twins, LTDs and Bs, I can ensure you, that despite any geometrical values the frame and the setup of a B is the much better rideable bike !
Bs are more active, forward oriented.
LTDs are some kind of relaxed lean-back riding 😉
I love them, both.

The engines can be swapped (beware of different upper engine…[Read more]

Hi Mike,

that shown page is part of the delivered paper documentation.
Much better is to go to their website documentation:

Just saw that it is still in german language but you can see three pic-links in the…[Read more]

I am on holidays now and will try to get two engines repaired/restored during that time (til 8.Jan.2017) and to find the best parts that can be used for my big bore engine.

If any pics of the internals of an engine are needed, just shout out.

Work with KK to get the needed parts.
I may have some if required, but shipping is from Germany…[Read more]

Hi guys,

I decided to make myself a X-mas present 😉
It is a digital ignition set from Sachse.
288,- Euros plus shipping.

Hi Andy,

just found this post.

Oh yes, that is a part of my youth !

Thank you for that link into the past 😉

Cheers, Michael

Thank you, Phil.
Same to you and the other twinners.
Let there be peace in the world.
Cheers, Michael

Hi Kenny,

that is to bad !
Thank you for the pics.
Looking forward to see what is in the oil sump.

Cheers, Michael

Hi Andy,
hi AtLarge,

I’ve ordered one pair of boots for each of you and will handle payment with Reiner and you and shipping to you as well.

That means, I am your SPoC (single point of contact) 😉

Cheers, Michael

Hi AtLarge,

thank you for your confirmation of the order.

It is counted in and production has started.
Reiner can’t produce more than 4 boots (2 pairs) per full day.
As I understand you don’t have a rush.
For me it is the same.
RELAX 😉

So expect the boots to be finished in January 2017 plus shipping time from Germany to you.

Once having…[Read more]

Hi Andy,
I will order a pair for you 😉

Hi AtLarge,
I am not sure if that is an order that you have placed.
“OE even” is not clear to me, sorry.

We just need to ensure that either you or me are placing the orders on the german Twin website to avoid double orders.
Might be easier for me to do that and I will look after “international…[Read more]

Hi all,

we managed to find a local manufacturer for the LTD airbox to carb rubbers !

Find the full story in the german Z750Twin forum:
http://www.z750twin.de/zforum/showthread.php?tid=2544
Very nice technical drawings included 😉

It was absolutely critical to get the LTD boots done, as they harden and shorten.
The B-boots don’t have that issue…[Read more]

Hi Kenny,

the fixing of the points cam holder uses a special “washer” with two grooves and a hex-head.
http://www.cmsnl.com/kawasaki-kz750b2-1977-usa-canadamph-kph_model15507/partslist/57923.html#results
Number 18

The points cam holder has two “noses” that match with the grooves.

It may be, that the “noses” are broken off. Not nice, but not a…[Read more]

I was not aware of either facts Michael. I would guess that the different materials are required for heat issues but maybe it is to keep the weights balanced?

Hi Kenny,

that’s to bad !

I am still wondering that the engine turns with that damage.

Heavy bending of the con rod and the destructed “foot” of the lower eye looks like there is the issue with seizing.

That bearing is oil-pressurised and the oil pressure can go away especially at this bearing if the large starter clutch wheel, that sits on…[Read more]

BTW:
As a gasket set use the VESRAH ones.
Do not use Athena ones !

Hi Kenny,
the big bore set was offered to me after I have asked a lot of engine reworkers to do that for me, but it was close to impossible !

The needed parts are not easy to get and the closest pistons (Ducati) still need some rework.
Find a report with some details of another modified Twin:
http://www.z750twin.de/Manfreds_LTD.htm

This shown…[Read more]

This is how the piston surface should look / feel like:
right hand side is a stock piston (78mm), left hand side is a big bore piston (86mm).

If it has a “burn-in”-hole, it should still move up and down, but may end up like the poor one.

All the best !

Cheers, Michael

ROFL !!!
Thank you !

Did you expect that the weight of the inlet and outlet valve is close to be identical, even with the inlet valve having a larger head diameter ?
About 80 grams each.
BTW: Valve stem diameter is 8 mm for both valves, which is very solid.

Did you know, that the exhaust valve is made from two different materials ?
Tested it with a ball-shaped…[Read more]

Well, this was sitting in the garage unattended for a long time.

After checking what would be the next steps I finally decided to get some new or modified camshafts !

There is a company called Megacycle in the US that do that modification, but I have found a company called CAMPRO in Germany and they offer the same modifications.
Lower Price,…[Read more]
