Roma Custom Bike is the first web-series about custom motorcycles made in Italy and distributed world wide both in Italian and English. The show starts from Custom Cez's desire to document his bike's restoration process. It was supposed to be a simple docu-tutorial, shot with a single camera so that he could keep it as a memory of passionate and creative work.

DIY CV Carburator Rebuild and float adjustment - ep 18 eng - Roma Custom Bike


Custom Cez explains the carburetor rebuild and adjustment on his CV

Harley Davidson carb.

In this episode we tackle the rebuild process from the carburetor cleaning to a few modifications and especially the float adjustment of a Harley Davidson CV carburetor utilizing a standard rebuild kit.
Everything is home made and DIY as usual!

It has been pointed out to me that the way described in this video is not the right way of replacing the main slide membrane, the BEST WAY is to purchase the SLIDE/MEMBRANE replacement together!
