Hello again

There has been a break in the update.

I've been in the garage and got some work to do ahead.
At first I lost the tig welding machine, and I was forced to buy a new one.

Although we have a high quality mig welding machine I didn't like to do it any weldings. Only something like small welds.
When I got a new Tig for the garage, I lost motivation.

Now I've made parts here and there, with no exact direction.

The battery case is almost ready, I got the original battery in my own opinion well hidden.

A protective plate has been made under the bench for the second time, now it fits better.

The seat still needs an upholstery

who sells cheap flat slide carburettors?
i don't have oem carburetors at all, and no tüv type certificate is needed here.
I have an xs650 equipped with Mikuni tm33 carburetors that I bought used. it goes well with them.

I'll add one picture of another kawasaki. Made it with my friend years ago. The engine is the only part that was not modified.

I read this forum and noticed that there are problems with the rusting of the chain tensioning screws.
Well, I made a few holes in the rear swing so I can check the pipes for rust.

The clamping screw on the brake side was very rusted, but I was able to remove it intact. It required several times of greasing and back and forth screwing.
The right side tensioning screw was in good condition.

From the holes I made, it was good to see the condition of the pipes from the inside.
The left side was already slightly darkened but not rusted,
the right side was flawless, although the tightening screw on this side was heavily rusted.

I closed the inspection holes in a different way than the factory had done.

When removing the rear tire, I found the reaction rod of the brake drum to be aluminum. I wanted to modify it to be less factory made.

I also added grease nipple to easy maintain swingarm beatings

Hi Mikko,

keep an eye on it that you use high quality and well dimensioned Material for the reaction rod, otherwise it could be end like here

Bremsanker

Best regards

Thank you for your message. Something similar has happened to me once. The reaction rod from the rear end of my xs650 motorcycle came off while riding. Inadvertently, I used the rear brake and in a fraction of a second the operating rod was broken and the lever bent. The spreader was also broken. Fortunately, there was no other trouble.
I would believe that the current part will withstand future braking, even though holes have been drilled.

Do you screw in the grease nipple from the upper or the lower side of the swing arm?

On Sunday I made a bracket for the carburetor. I borrowed the flat slide carburettors from the xs650 daily ride because the w carbs are the same. The filters are borrowed from my Kawasaki gpz500 flat tracker.
The bracket is made of stainless steel bar and flat bar. It was easy to do, just a thread on one end and a little tig welding on the other end. I'll make the threads in the frame after I disassemble the engine.

Do you have a silent block between the frame and the bracket? It is not good to connect the carburettors rigidly to the frame. They must be able to swing freely.

I have supported the carburettors on the engine. This way they have the same vibrations as the engine.

Good point, thanks for that Falcone!. I put a cylindrical insulator on it. It's easy, I shorten the bar enough.

Some development in the garage.
I dismantled the w650 so that I could grind away the remains of the support plates and unnecessary supports.
The speed holes for the back tube still need to be done.
Seat is slowly coming, i have not graet skills on sewing machines

This project is now on hold, I'm low on money (thanks Putin and friends).
I need to upgrade my xs650 for next season. The handlebar needs to be replaced, the footpegs need to be raised and the clutch plates need to be inspected. The bar and pegs come from stock supplies, so i don't have to spend any money at all.

I messed up the frame more. I drilled speed holes in the back tube because the square tube looks boring. No other progress has taken place.
There was no rust inside the pipe at all. It's probably because it hasn't been driven much and hasn't been stored outside

Notice the porous welding right side of frame
