hi all. I recently bought an Aprilia RS50 moped after sitting for 3 years. It drives great, started from the pushrod even without rebuilding the carburetor. but there is one problem, it won't start with the button. I found the location of the starter relay on the left side on the back side of the frame, apparently it is attached with a screw to the plastic battery niche. Has anyone found out how to remove it? without dismantling the entire moped?
