Michael’s engine rebuild

[Michael]

Hi Boys and Girls,
Ladies and Gentlemen,

I start an own thread to give you some more information about my engine rebuild.

That was the easy part.
Removing the cylinder bank / barrels is always a challange.
Today is the third day of trying, slapping and soaking. Pried it off eventually but broke a cooling fin.
Removed engine covers and and starter motor as well.

Cheers, Michael

I have removed the valves from cylinder head:

What do you think about the black exhaust valves seat ?
Where is that coming from ?

Cheers, Michael

OK Now that looks complicated! I’m a little apprehensive about attempting something like this. 🙁

Hi boyZ and girlZ,

today is my last working day this year !
Holiday until 6th January 2015, hurra !
Back to work on 7th Jan., ooooh !

This evening I will pick up a crashed Z750LTD Twin, Y1 and “lock” it away in my shed. Needs further investigation what is ok and what is bent.

Tomorrow I will clean the other parts of the engine and on Thursday I have a date with Mr. Gaenssle himself 😉

We will discuss what can be done with the engine. I am really curious what a specialist in engine rebuilding and tuning has to say about it 😉
… and what the prices are ?!?

Keep you posted 😉

Cheers, Michael

Don’t keep s in suspense for too long . . . .

Hi guys,

the date with Mr. Gaenssle was disappointing!
He is not doing full engine restorations anymore. He is “only” doing the explicite mechanical part of that job.

I am in contact with Ulf Penner.
http://www.tuning-fibel.de/
He is a motorbike mechanic and has written a modern “book” about engine tuning. He is willing to help me finding more power from the engine and to support me with further information.

Well, some progress:

the valves:

valve shaft diameter is the same size in and out

more pics:

cylinder sleeve in engine case
(engine is upside down)

engine case is not maschined to match the sleeves. There is a minimum of 1 mm gap between sleeve and case. At some places there is even more than 1,8 mm gap between them.
