1990 CG125 Oil breather set up? (Photo - She's a beaut!)

[Matt Freeman]

Hi, I have a 1990 CG125 Brazil, she's a lovely old girl

I got her "stolen recovered" and have given her a kind of custom restoration.

There was nothing connected to the sump breather when I got her so I just fitted a black pipe that runs vertically and then forward under the tank to the front of the bike.

On high revs she "vomits" oil all over herself and me.

Is this due to an over pressurised sump (piston seal problem?) or is it due to inadequate breather set up?

So my question is, does 1990 CG125 Brazil have a catch trap in the standard breather set up and would this solve my problem and save me having to strip down and potentially re bore the cylinder?

Many thanks

all my breather did was come out of the spigot out of the crank case and go straight under the bike between the swing arm and main frame

your set up might be no good as its here there nd everywhere

you'd be able to tell if it needs the rings changing as it would be smoking blue from the exhaust

Thanks for the reply.
To clarify, your breather had no hight on it? Just an open pipe travelling a few inches and blowing down onto the road?

Are there other reasons that the sump would become over pressurised does anyone know?

Funnily enough, my other ride is a Royal Enfield Bullet which also had oil breather issues (resolved now.)

Thanks, the oil level is half way on the stick.
Perhaps my long pipe causes it to get blocked and then burst the seal when I rev it hard and blow out like a corked gun....

I'll have a play with it.
But it sounds like I won't have an engine work to do?
Many thanks.
