Frequently Asked Questions
How many pulse-generator cover gaskets replacing Honda OEM 30372-437-010 are included?
One pulse-generator cover gasket replacing Honda OEM 30372-437-010 is included for listed 1976-1982 Honda CB125S applications; one gasket for the pulse-generator cover.
Should sealant be added to the pulse-generator cover gasket?
Use sealant only where the Honda service manual explicitly specifies it. Extra sealant can alter clamping, squeeze into an oil passage or make the next service difficult.
What surface preparation helps the new gasket seal?
Remove old material without gouging aluminum, clean and dry both mating surfaces, check for warpage or damaged threads and tighten fasteners in the Honda sequence and stages. Correct the source of any distortion before assembly.
