Andréj hello, your article on strengthening your framework is very interesting. I plan to do it on my 3 Wheeler from May 2012. It has a lot of vibrations and on French roads which deteriorate it becomes problematic.
I have many qustions :
Where did you place the reinforcements in the tubes?
What is the diameter of the reinforcement tubes?
How thick are these reinforcement tubes?
How did you manage to push in the tubes? Did you use lube?
Did you weld them to the chassis? If so at what levels?
Did you have to disassemble the engine?
Have you been forced to undo welds?
Have you treated the inside of the tubes against rust?
Concerning the new mounts for the silentblocs, did you make new mounts or modify the old ones?
Do you have plans for these supports?
If you have other photographs, I'm interested. I thank you for your collaboration. Sincerely Marc Joulin.
