oil leak behind countershaft

[freemich-be]

Hello Guys,

I'm new to the forum and have recently purchased a 1975 cb125 with a 200cc engine.
A few things I did:
- Changed the clutch plates
- Put in new 10w40 oil.

The bike runs well but immediately after riding it starts to leak behind the countershaft.

It's strange becauce before we changed the oil and clutch plates there was no leak at all.
The oil level seems to be ok, so I think that's not the problem.

Any advice from someone whos had seen this before?

Your best bet is to remove the sprocket and clean everything up real good, then you'll better be able to determine exactly where the leak is coming from. There are a number of oil seals in that area, just a matter of finding which one is the culprit.
