New speedometer support, that's interesting because the broken one is in steel and the new one is in plastic, they are a little different

Hello everyone
When I was riding with the bike one year ago, it was leaking some coolant from the radiator but I couldn't find where exactly
So I cleaned the hoses and put some air pressure in the radiator, also with some soap on it so it can make some bubbles if there is a hole.
Heres the hoses before and after cleaning
Heres the radiator, he's not in a good shape,
And here is the little hole where it was leaking by
Also Here is a new gas cable

Since I had some issues with my white wheels, I went to a motorcycle wheel specialist with my white wheels and also my black wheels I recently bought.
So he said the white wheels are completely unusable, but the black ones are in a pretty good condition, there was just an imperfection on the rear wheel but he fixed that for me for free and said dont touch it anymore or it could be worse , he also said the grimeca wheels are the worst type of wheels because of their steel type, you can just destroy them by placing bearings with a hammer.
So now I want to do an epoxy beautiful white paint on the black wheels like the previous ones, just because I have trust issues I cut my old brake discs and put them on the wheels, so the brake disc areas are protected from sandblasting and painting.
Now the rear wheel
Yeah I'm a psychopath but the discs were old and used, I also have new ones so dont worry.
I'm also searching for a solution to protect my bearings areas, my coworker asked me to put only the exterior part of the old bearings so the're will not be some grease on the fresh paint if I put the entire bearings, so I've done exactly what he said but I realized its gonna be difficult to take them out after painting.
Dont worry i didnt put them on the wheels anymore for the moment.
So do you guys have an idea to protect my bearings areas ?
How can I do ?

Honestly, you shouldn't need to do any of that.
The problems may come because of aggressive media blasting to strip the wheel. When I strip a wheel I do it chemically, and the media blasting is very moderate - not enough to affect the mount areas for the rotors or the bearing pockets (no need to blast down into the bearing pockets).
If you wanted to protect the bearing pockets you can use a rubber stopper, and tap it into the opening securely.
The areas where the rotors mount and bearings seat should be masked, after prep and cleaning, before painting or powder coating.
You need to find someone that knows what they are doing so they don't wreck the wheels.

I think I will search another paintshop that will do some great job, maybe protecting bearings areas is useless, maybe the painter doesnt want me to protect these so he can do it himself if he want.
You're right I think I will not lost my time with these bearings areas.
Now I just have to find a good painter that can do it and just hope he wouldnt wreck them again
Thanks you again jkv
