Vito’s Yamaha Blaster .020 Base Gasket
The Vito’s Yamaha Blaster .020 base gasket provides consistent cylinder-to-crankcase spacing for Blaster top-end repairs and performance engine builds. It fits every Yamaha YFS200 Blaster produced from 1988 through 2006.
Base-gasket thickness affects cylinder height and can influence port timing, compression and squish clearance. This .020-inch gasket is a useful option when assembling an engine to specific measurements or replacing a gasket of the same thickness.
