I just had my carburetor rebuild on my 1973 CT3. It fires up first kick and starts off strong. It seems to bog down when it gets close to red line. Especially when I’m going up a hill. It kind of sputters right before I’m about to shift. Does anybody think this could be just a simple adjustment on the carburetor?

I was wondering if the “Yamalube 2S” is a good/recommended to stroke oil for my 1973 CT3. I just rebuilt the carburetor and freshened up the whole bike! I’m ready to launch it fresh and wanted to start off in the right direction.
