Motorcycle Repair: petcock removal, honda cl100, google search

Question
I have a 72 Honda CL100 that I just started working on. I have spark and it will start with starting fuel. What I need to do is replace the fuel petcock because very little fuel is coming out even after several attempt to clean it out. My question is how can you remove it from the tank? It doesn't appear to spin out or have bolts to remove. My guess is that it is riveted on. Any help would be appreciated.

Answer
I'd never heard of a CL100 before until you asked your question. I did a Google search and found a replacement fuel tap for your bike, but the photo of it doesn't offer any clues as to how it is installed on the gas tank.

Go to: www.onlinemcparts.com and you will see the photo there under "CL 100" parts. My apologies, but that's the best I could do for you.
