Welding a washer sounds simple and cheap... We have a solution here.
Washer I think has to be thick so you can weld it. Painting it later is a good idea to prevent rust.
I have shortened my sidestand, I went through cutting welding,...I should have used a big ass washer then.
Now I like to have an aluminum piece as foot expander.
The air filter base should be easy to make. Send me your template.
