I have an universal rearset
This one from tarozzi:


I'm planning to make the 'schetsplaten' (sorry, don't know the English term for this) myself from aluminium.
If you take the raask ones


I want to copy the backplates, so you don't have to welt, drill or anything.

But when doing it, I will make a tuttorial.

They seem different from the ones I need but we will see.

BTW I bought a perfect set of goodridge steel brake lines (for the XS750) on an englisch ebay store for only 66.99+9.99 pounds (90 euro)
For a Honda cb750 the price is the same.

You don't have to be affraid of the footpegs.
Although they are huge indeed, they are positioned so high, the exhaust will reach the ground first.
You are really folded on the bike, like the propper races of old times.

All right, time for some pictures.

It looks there is not too much done, well I sure spent a lot of time in the electronics (still busy).
Also did a lot on diy jobs in my house (not fun! )

Anyway:

Mounted the front springs (also bought some rubbers for it), clip-ons, frontbrake lines and front fender




As I said, the electronics. Everything checked and replaced if necessary.
This is gonna be a side-cover on the left side (a part of it Very Happy):



Changed the place of the ignition-key


Made a aluminium plate to cover the gap when leaving the airfilter.
I'm doubting about taking kelks or airfilters. (do you advantages or dis-advantages?)


Wheels ready to be sent to Haan Wheels


assembled the carberators with a littlebit of polishing. Sonic cleaned, thanks by Tintin , also mounted revision sets


Switched the original ingnition to an electronic. This costed me two days! For crying out loud!
The screws were a total mess. everything drilled out and cutted new screw thread.


What to do:
- rest of electronics, dashboard half made.
- side-cover
- brakes (waiting for 2 rubbers)

As you may have red in my topic about the tank, I'm gonna stick to the original tank.
But what I do want are dents for my knees.
Like this:


Can anybody help me with this?
I know the instructionfilm on youtube, but I think this is above my head Rolling Eyes.

Thats it for now

Hey what kind ( brand ) of ignition did u use?
Doesnt look like the " familiar" Boyer brandsen..
Thinkin bout installing this too (damn mechanical retarding system!!)

My opinion about open air filters vs. venturi's (kelken):

Airfilters are more easy to tune
I think they are more suitable if you ride your bike often
Citytraffic ( low rpm ) is easier with filters

Venturi's look great! sound great gives your more possibilities in high rpm but suck at the traffic light..
and when it rains or the road is wet, too much wet air gets in.......

If i'm wrong please tell me this is only my personal experience(maybe i'm doing something wrong myself)

He CJ.

It looks great!

When you are using kelks, all dust, sand, water etc will get into your carbs.
All this shit will get into the little holes of the messing parts etc.
The rebuild of your carbs is than not very usefull.
I would advice air filters.

Pure racers have kelks, because the overhaul the carbs maybe every race.

Is it possible to put some foam in the kelks so dirt can't get in?

So, last day of my winter holiday, so time for an update Very Happy

Kick off with my tank.
As you noticed I was in doubt of what to do with the tank.
After a lot of thinking and watching the youtube movie a dozen time, I decided to make the knee dents myself.
Before:

After:


The new cockpit/dashboard. I'm very pleased with the result. Very Happy Very Happy

The switches from left to right (high beam, lights, dead engine, start)

Made an alternative place for a new fusebox (a modern one).
Also placed a new battery.


I was not happy with the plastic sidecovers. Not the right look.
So I made one.


And one the bike:

(also mounted a new sprocket)

In time there will be an hole for this little airfilter. It's connected to the breathers.

The exact location is not sure for now.
I have to wait to see how my legs are, when sitting on it.

Mounted the headlight, brake and clutchlever, ande the goodrigde brakelines (part of it)
For the clutch lever I buyed a secondhands one. Of that I only used the mounting for on the handlebar.
The (original) lever itself is adapted to this mounting. So I have two the same levers (both polished of course).


YESSS!!!, my wheels arrived! cheers cheers

DAMN they're sweet!

Some pics of 'the shop' Wink

Polishing corner


All right, that's all.
Next time I hope to show you a bike on wheels, instead of on the floor.

Hey Cj,

The tube with the filter is gonna get all dirty and oily, if i where you i would not place it near your clothes..
Don't put it to close to your rear tire too, if it spills oil on your tire....

cheers

Hey cj

another thing to take care for.
If you switch levers you must be 100% sure they have the same lenght in there action, especially with the brake lever.
I once adapted my original kawasaki lever to fit a newer existing brakepump.I had to rework the entire shape of the lever, but it turned out that the lever did not fully come out.
So the brake pump always kept 1mm pushed inward. If this happens the pump keeps a little of the pressure. after a few kmrs testriding my bike didnt want to move a cm anymore.
I noticed my brakes got stuck...and i couldnt figure out why. After braking several times the small amounts of kept up pressure tottally blocked my wheel
Later i figured out that it was the lever..
Maybe you didnt change it at all but if you did i just wanted to let you know. i spent some hours looking for it so....

Very very nice job!!!!
I am really impressed. I love the knee dents in the tank. Brave that you have done it.
Are you going to put tank-cure in the tank?
Spoke to some motorcycle mechanics today and the where all very enthaustiastic about it.
I will use the stuff probebly. Especially after the overhaul of the carbs.

Good luck, but I don't think you will need it

Thanks chaps!

@ z666:
The little airfilter is only attached to the crankcase ventilation. (the one from the valvecover)
Brakelever is completely original, only polished.
Clutchlever is not, but if a problem with that occurs, I can adjust it.

Youtube film is actually a tutorial topic on this forum:
click here

@hofman:
Yes I'm going to use tank cure

All righty! Very Happy

Did A LOT!

Got some new bridgestone tires, and damn! they look sweet!

I also mounted a new sprocket (45).
The discs are not new, only the heart is freshly painted.

It was quiet a struggle to get the wheels on the bike.
My wife was really helpfull, putting the front wheel in while I was lifting the bike...... Very Happy
When the frontwheel was mounted I could finnaly assembly all the parts that were waiting for so long.
The brakes are completely overhauled.



For the frontfender I'm planning to make an oldfashioned licenseplate. Maybe I'm just gonna order it at carpy's.

Rearwheel, also with a brake overhaulin and Goodridge brakelines.


Some small stuff, but very happy with it:
A chrome gaslever with the right handlebar grips.


When the bike was a real bike again, I started thinking about connecting the seat.
Inspired by Hofman I started to make an sadlepan out of epoxy and glasfibre.

First made this:


Using this:


To make this:

(you can see my silicone air hoses for the carberators in the corner)



Painted black and 'on the project'


The pins are bonnetpins, so I can 'lock' the seat to the bike.
After all I decided to go for a ducati seat, It has quiet the same dents as my tank.


All together, with mounted rearlight.


Next things to do:
Install rearset,
Install carbs with filters or kelks (still not sure.......)
Paint, paint paint!

Hi guys,

This evening I started to fabricate the backplates for my rearset.
I have a 10mm thick piece of aluminium what I want to use.

So I made some exaples from cardboard, draw them on the alu. plate.
And now the frustrating part comes in:
How can I saw it out?

Anybody good idea's?

Decoupeerzaag smelt....... Shocked

Wat voor zaagje? Een ijzerzaagje houdt het 5 cm vol....

Je moet de snelheid van je zaagmachine vertragen, als je dat kan met jouw machine.. anders heb je pech denk ik..

Aluminium smelt sneller dan ijzer->trager zagen --> minder hitte..

ik doe het altijd met van die 1,5 mm dikke slijpschijfjes, eerst slijp je de vorm er grofweg uit, en daarna werk je het af met de afbraamschijf, dit gaat echt super!
