After a lot of troubles I ended up installing a Dellorto carburetor, the bike starts easy and runs very good now.
After the installation of the Dellorto carburetor I just had to figure out a way to install the aircleaner, but together with my father we found a sulution. (no pictures at the moment)
I had promised myself that I would not put anymore brass at the bike, but in the end of the fender struts I had installed stainless acorn nuts, and it looked very modern, so I decided to Install two brass wing nuts I got from a guy named Rolf, thanks body !
I had a few oil leaks at the bike and some clutch issues witch is also corrected now, that means I will soon be riding the bike all over the country.
