Leak Help
« on: June 01, 2018, 12:24:40 PM »
Hey fellas,

1974 CB750K
Any of you fellas ever have a leak off to the left side of the bike and under (maybe from wind). I’ve attached photos. Under sprocket cover.

Thanks in advance

Pull off the transmission cover and replace the gasket.  Put a non hardening thread sealant (ARP, etc) on the screws.

I agree. The oil all seems to be on the fasteners. Probably just a bad seal around them. If its a re-used gasket, then very likely.
