I have come to another crossroads in my build.
I have a 76 CB750F that I'm working on and have a bit of a predicament on the tank
When i bought the bike i got an extra tank with it. Both F model tanks.
The extra one has the petcock on it but is full of rust pinholes.
The tank im using is perfect, sealed, and ready to go. But has no petcock.
When i went to swap it out thats when i realized they are different size threads.
Is it true the 75/76 F models had a different petcock than a 77/78?
And if they are, which one has the smaller thread?
Thanks!
