Yes, the water seal is leaking. This is the indicator hole for the water and oil seal.
Enjoy the ride !

SOURCE: what oil should i have in yz 125 2 stroke

The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.

I have a 1996 Yamaha yz80 that oil is coming out the exhaust pipe. I am running 40 to 1 ratio gas oil mixture. Any ideas what may be the problem?
Two strokes just leak oil especially where the pipe meets the motor you could try new oring but seriously only be worried if you dont have oil leaking from exhaust on a two stroke is rule of thumb

Tons of smoke coming out of exhaust
A bad crank seal on the right side, if bad, will **** transmission oil into the combustion chamber. This will smoke badly.

Leaking oil from power valve on 2000 yz 125
It is normal for the powervalves to leak, but it does depend on where it is leaking from.

The hose on the left side is the power valve chamber vent - it is normal for it to leak thick black oil from this hose.

If the leak is on the right side, and the oil is transmission fluid, then the seal on the actuator shaft needs to be replaced.

Excessive oil from the powervalve hose is a possible sign that the compression is low. Low compression equals lower exhaust temperatures and this can lead to incomplete combustion.

When i kick my 85 yamaha yz 125 gas and oil come dripping out of my engine where the exhaust and engine meet ? Helpppp
Sounds like you have blown the exhaust gasket. Not a difficult repair .. just undo the exhaust manifold bolts and remove the exhaust. Purchase a new gasket and reassemble with the correct torque settings.
