Howdy - found some good answers on this forum while rebuilding a Suzuki 50 my buddy bought - but still running into an issue.
We replaced the whole top end with this kit -
New Suzuki Lt A50 LT50 Cylinder Piston Gasket Top End Kit Set 2002 2005 | eBay
Problem is, it doesn't have the vacuum port on the cylinder where the carb bolts on. Also, the cylinder that was on it, doesn't have it either (vacuum port is just hanging). Has anyone bought one of these and had success drilling and tapping and adding your own port? Guy on ebay is being accommodating but looks like I might have to return it and he states none of his have this port.
