...and here we go... ;D
If anyone may have thought about how many swarf are produced while turning a hub just take a look at the first pic! ;)
The upper hole was the first I tried the footpeg on but it was way too high. So I drilled another one and now it´s fine. The gearchange-lever looks the same as the brake-lever. I´ve to mill the plate so that it all will be stiff an light.

well man, you certainly have an interesting way of working...

why not make a test with a 10mm plywood piece to find the right position and only then cut the expensive aluminum plate? :)

Not sure i understand the logic of turning a whole front hub either when you could instead just make simple disc carriers or use the excellent suzuki GS 280mm discs that already come with the right 6 bolt pattern... but hei, you seem to be enjoying yourself no? wish i had that kind of machinery in my one car garage... I am jealous!

By the way, i wouldnt attach the footpeg bracket so high, your plate can become quite flexible IMHO

Keep up the good work

Achim, I am also going to make some new foot levers and rear-set mounting plates. Where will you attach the linkage to your levers??
I'm thinking I will locate the pivot of the levers below, and independently from the foot-pegs. I think this will provide a more solid mount for the pegs, which have to carry a far greater load than the shift and brake levers.

TG, my small mill, and my lathe only take up a space 10 feet wide, out 3 feet from the wall. The hub adapter in the 2nd pic I just made using these 2 machines. (It will allow me to fit a Kawa front disc to my Morris rear wheel)
Don't fix it if it ain't broke!

My Dad wanted to find the position quickly, so he used the aluminium plate. All I could do was sit and watch! ;D
By the way...the aluminium (7075) is comparatively cheap. For example...I paid 60€ for the material for the hub. The finished products you can buy are expensive.

I didn´t know which discs would fit the original hub (maybe I should have asked ;)) and so I decided to turn a hub. And as you wrote I like working with my machinery. ;D

You´re absolutely right regarding the flexibility of the plate. That´s why I´m probably going to weld a nut on the frame to fix the plate. It has to be welded somewhere near the swingarm pivot.

...you don´t have to be jealous...I´m glad to be able to move in the garage because of the little space! ;)

Scottly:

Your hub adapter is a very nice piece of work...well done! ;)
I´m not sure what you mean with "attaching the linkage". In my case the pivot of the levers is also the stud for the pegs.
But you´re absolutely right regarding the load the pegs have to carry. Otherwise the pivot/stud is thick enough to carry the load. I will provide you with some pics later today. Then you will also be able to see how the rear brake will work. I´m going to use a wire instead of the original rod.

Hi Achim,

A nice piece of work you did.
For positioning the levers I made alu plates with many holes in it.
During the season we made some changes with the lever position.

Thanks for the complement, but my adapter is in no way as complex as your hub!
The linkage I referred to is the rod that will link the shift lever to the shift shaft on the motor, as well as where the wire will attach to the brake lever. Pics will help..

That´s Dimebag Darrell...former guitarist of Pantera and probably (in my opinion) one of the best rock guitarists who ever put his hands on an instrument. Sadly some #$%* shot him on stage.

@Scottly:

I haven´t worked on the shiftlever so I don´t know how to connect the rod to it but I´ve shot some pics of the brakelever where you can see how I attached the wire. The "stop" for the lever (that round thing that stops the lever from going up) is mounted off-center, so that the position of the lever itself can be adjusted. I hope you understand what I mean as my english has seen better days...

Achim

Very nice! Your english is quite good! Where you used the term wire, I understood it to mean cable. I have more trouble understanding the Brits and the Aussies!! ;)

Hello,

finally I finished the rearsets. If anyone wonders about the design...my Dad wanted me to build them like this. They look a bit like the parts on racebikes in the 60´s and 70´s where everything had been drilled. Holes are lightweight! ;)

Very nice done with the brakecable in the lever.
But for me personally speaking to much holes , it looks like swiss cheese  :D :D

Hello,

sorry that it took me so long to reply, but I had tons of work to do!

The following pictures show the bike as it is now. I have also photographed the starter I made for it (because I got rid of the starter to seve weight).

As you can see I redesigned the rearsets and still haven´t finished the triple clamps... :-\
The painting has been done in a tent in my garage. I hope that I´ll never have to do a nasty thing like this!
The megaphones once were straight so I cut, welded and painted them. I bended the manifold out of 1,5mm tube.
I bought some used Keihin CR 26 carbs but a few parts are missing...can anyone help me with the sizes (needles, etc.)...the engine is (still) stock.

Regards
Achim

looks really good man! compliments!

my only comment to you would be that those small honda discs  will not stop so well from my experience. did a race on a friends bike and didnt like them,

what calipers are you using? look like brembo 05 or 08
