With SMART,

Er zijn speciale zaagjes voor aluminium te koop, en inderdaad lagere snelheid doet wonderen.

Grtz Frank,

PS, je kunt ook de rear set van mij kopen Embarassed ben je gelijk klaar. Very Happy

Haven't done as much as I wanted last time.

One of the major reasons is that my 911 was so soaking wet inside, that was first priority.
So the garage was occupied with my other love, to dry.
But I guess that problem is for another forum..... Wink

What DID I do:

Spent a lot of time on my backplates of my rearset:





Some small stuff:
Made a place for the breatherfilter:


And mounted the carbs:



Further more I have this strange problem.
When I sit on my bike riding backwarths. When I want to turn to the right (so steer to the right) everything is runs smooth.
However turning to the left, something stucks (loopt aan ofzo).
Does anybody have any clue?

PS: in a straight line: no problems

So, long time no see Shocked
Last saturday I returned from a 6 month deployment in the Gulf of Aden and the Mediteranean.
So 6 months with almost no progression (I was 5 days at home for a midterm-break)

What's the status at this moment:
Bike looks like this:

As I told before, I have a serious problem bringing my brakesystem under pressure.
So now I'm trying it apart from the bike. After it's working again (and not leeking), I will have to respray every part.


A good friend of me, sprayed the tank and the seat.
Furthermore, there a several parts waiting for assembly, or spraying.




The color is: very dark blue (blue hollandaise)
The white color is: classic white. Both are colors used on Alfa Romeo's

The pedestrian-slicer (so-called) do I have to spray blue, for my license.
The rearlight will be white also.

Furthermore I added a set of K&N filters. I was in doubt for K&N or the cheaper version, however in Germany there a much cheaper! Idea


Things to do: (and several questions)
- spray rearlight and assembly
- spray pedestrian-slicer and assembly
- get te fr@#king brakesystem to work, spray and assembly
- make an licenseplat mounting,
Does anybody know where to order a blue licenseplate (the little ones)
- Clean tank (with tank cure or something simular)
- Assembly of exhaust.

Last question: do you guys know where to get this cool colored bolts (blue and red)?

I've now 7 weeks of holiday, so I guys a lot of updates will follow upcoming weeks.

Please, please, please DON'T use those colored bolts you're looking for. They look so wrong on an old bike in my opinion (unless the whole bike is newly chromed/polished).

I ordered my license plate at a local Ford car dealer, had it in a week or so.

Hmmm, not to many reactions.
However I wanted the whole project posted, also the last part.

Almost finished now. only small things to do like calibrating the speedometer, mounting this pedestrian-slicer.

Piccas:








Color is more shiny inreal life.
My driveway is topped up with snow, so these pictures are inside, not on some nice spot.

YES!!!

Did some testdriving and I am a very happy man.
There are a few minor problems however to solve.

1.the heat resistant paint on my exhaust seems to be not so heat resistant at all. So paint again.
2. Aft brake cilinder is leaking, so have to fix that.
3. Also 2 major oilhoses are to old and are leaking oil.

At this moment the seat is being made.

I'm searching for this stail breaded oil hoses for a CB750 but can't find them. I'm very sure they exist, I saw them once.
Has anybody an idea where I can find this ones?

Need help!

I'm in war with my speedometer. And I'm losing pale
At this time I ruined three and spend a big time doing it. It just won't work to get the ring back on the two halfs Twisted Evil . I'm totally through with it.

A not to mention cafe builder uses this kind of clamps:


Does anyone know where to get these?

I'm starting to get desperate.

Long time ago...
Didn't drive a lot. Mostly because a bad functioning timing chain tensioner. Timing changed because the shitty thing broke.
So now I have a lot collateral damage on the whole engine.

This weekend was D-day:
I was pretty not amused by what I saw.

Pistons damaged.



Can I use this again? Not quiet experienced with this kind of repairs.

All valves are bended. affraid


So I'm gonna replace them all.

At this moment I'm in doubt of installing a big bore kit.
Does somebody has a cheap address for drilling up the cylinders (not knowing this is the right word Rolling Eyes )

I will keep you informed about the operation

maybe its cheaper for you to buy a used engine.
i have a later model cb750 engine for you whit dohc. i guess the monting points are the same, than you dont need a big bore kit also because this engine has a lot more hp.

That's an option I also reckon.
I will keep it in mind, however I prefer a SOHC (for this moment).

Do you think I need other carbonation for DOHC?
