Cylinder base gasket 0.5 mm – 4T 2V, 3V and 4V (Piaggio / Vespa original 969230)

Remove the old gasket (or gasket residues) using a gasket scraper.
If the surface is uneven or damaged, apply a small amount of liquid gasket to prevent air leaks. Thoroughly degrease the surface with brake cleaner, then apply a thin layer. Allow it to dry/cure for approximately 10 minutes, then assemble.
