CB500 K3 Oil leak
« on: May 05, 2022, 11:24:21 AM »
My 1978 CB500 K3 is leaking a lot of Oil… Can not see exactly where it is coming from, what should i look for first? Since it is a K3 I believe the engine block is similar to the CB550 of the same year.

First off, I'd suggest cleaning the engine!  Gunk Foamy engine cleaner works good. Get it at your local auto supply.   Then sprinkle white baby powder on the engine, the oil will easily show up where leaking.

No one common point but loads of possibles, as said you need to clean it and find a leak are first then come back
