I posted a question the other day about engine ventelation and have not received any responses. I have a 69 T100R. I have just rebuilt the engine, and it's running pretty good.
There is a cloudy oily substance coming out of the breather tube, someone told me that's not unusual for the pre-primary case vented bikes and you can do some things to help reduce it by re-routing the breather tube. I'm just curious if anyone has had this problem and a fix for it?
Thanks for the reply.
Actually it is milky white drip of an oily substance out of the engine vent system when it's running. I'm sure it is condensation and an engine oil mixture. I have the vent from the engine vent tube next to the main sprocket to a T with the oil tank and a discharge tube to just below the frame between the frame and swing arm.
Thanks again for the reply.
Well, there you go pookybear, You do know what I'm talking about.
You just built a moisture trap. Where do you install this trap? Next to the vertical frame rail?
It's difficult for me to grasp an understanding of how the crankcase breather works. The vent valve rotates on the end of the intake cam shaft. I see how it vents out through the vent in the bottom of the engine but I don't see where it draws from (you know suction).
Well thanks for you help. I'm gonna keep expirementing.
