Anyone know if a 93 yamaha jog cy50 has a vacuum petcock , If so where is it located I've has the whole bike apart and never could find it anyone know of anything ,

And also I tried new oil and I put super in my scooter
I been running super for about a week now with no issues just better Pro-Formance and on Friday I put new oil in and yesterday I noticed that my scooter was lagging while driving , If I start out completely stopped and I slowly pull the throttle it usually gets the oil injected at around 10 mph and you can feel the pull once the oil gets injected the bike goes fast and moves quickly , now when it hits the oil injection point the bike just goes casually very slow compared to what it usually does anyone know if it could be just the oil because it's a brand I've never used before or does anyone know why I might be experiencing this thanks everyone for the help

It has 2 hoses leading to the carb. and one hose leading to the fuel tank. Goodluck!

I've looked everywhere and it's not anywhere that I can find and the gas line is just straight right to the carb and my carb leaks constantly but I added a fuel shut off to correct the problem when it happenes but it's not a full fix like a petcock vacuum would be , and I constantly have to play with it to have the bike working correctly , anyone have a diagram on how it's suppose to be connected to the carb so if I do buy one I know how to connect it
