If you decide to replace the radiator.

 

I have taken the radiator to a specialized workshop to have it disassembled and cleaned inside, next week I will have it ready.

NEW PROBLEM:
I checked the starter motor before installing it and it turned over when 12 volts were applied.
Once assembled there was no response when applying voltage through the power cable.
I dismantled it again and outside the engine the starter rotated when applying voltage to the terminal, at that point I thought it was a ground problem since I had painted the block, I scratched the paint and reassembled the engine, again with no response...

The terminal screw was capable of rotating about 40 degrees by tightening or loosening the nut that holds the power cable.
I realized that when I removed the power cable the starter turned, on mode.



In the opposite direction, when pressing the power cable terminal the starter gave no signal, off mode.



I removed the starter cover and found the problem, the connector has come loose, the solder has broken.
Tomorrow I will look for a workshop specialized in electricity that can repair the starter.

Work is piling up for me.

Good idea to refurbish the motor. Used to know a guy who clean them up, chuck the windings in a lathe, take just a wee bit off the commutator to ensure a true circle, clean the commutator grooves, reindex the housing for minimum current draw. Saved many a FJR Yamaha starter that way for the peeps.

I noticed that even my slimmest 10mm wrench was too fat to back fit the nut closest to motor housing, got the same twisting motion you saw. Ended up holding that nut with a pair of slim nose locking pliers to prevent that rotation.

Looking forward to seeing the radiator!


 

I now have the starter motor ready to install.




The insulator was broken, it had to be replaced.




The screw has been filed so that it can be held with a wrench while the nut holding the power cable connector is tightened.
Old school work.

That's a good idea. Well done.

I have already gone to the workshop to pick up the radiator.




This is what it was like when I took it to clean.



This is how it looked after treating the dirt and rust.


I have paid 80 euros for the work.
