Title: Advice on engine
Post by: jans on February 17, 2022, 09:54:07 AM

I am wondering whether this can be right or not? Is there a passage between the crankhousing and the insert hole for oil pump? When I overflood the crankhousing with petrol, the hole for the oil pump get flooded as well... is that normal?

I am working on a ZX from 2009

thanks

Should be normal (as far as I know), it has a O-ring to keep it close from leaking.

Same construction as Honda Dio, see video here:
