YAMAHA BANSHEE 72MM BASE GASKET .015" THICK. FITS SUPER CUB CYLINDERS.
We had this base gasket custom cut to match the transfer ports on a Super cub cylinder. The transfer ports on super cub cylinders are very large and standard base gaskets hang over into the port area disrupting fuel flow causing turbulence. We opened up our base gaskets to match the large transfer ports and to fit the larger 72mm sleeve on the super cub cylinder. This base gasket is .015" thick.
