Today job: Kickstand...

The kickstand was broken and the shaft rusted inside. I had to cut it and to do a new pivot.

I need to find a spring: Could you give me the size from the original one 😉?

Other item is the exhaust, my is badly cut 🤮

I found a cheap one in UK, to repair the old one is possible however the final cost will be the same (Welding, sand blasting, painting....).

Wait and see...

Broken screw, the one to keep the rear shock in place 😪.

The others one are removed.
