A thinner diaphragm pumps harder but doesn't last as long. Using a thinner gasket is a great trick for qualifying for 100cc 2/cycle or large engines.
Use this diaphragm on all engines 60cc or smaller. Small 60cc do not have the vacuum or pulse to operate the thicker diaphragms efficiently. We recommend changing this pump diaphragm every race day. Don't go longer than three race days for the best performance.
