So when you think you know the YS this happens....
I am in the process of braking in my YS 200S and I noticed that there was a lot of oil on the rocker cover after running the engine for a few minutes.The engine was very difficult to start and throttle response was very poor . Initially I thought this was normal as the engine was new and running very rich.
However on closer examination I noticed that oil was pouring under pressure from the rear bolt that holds the rocker cover ....*** ???
Is this normal and can anyone give an explanation as to where is this oil coming from ??
Thank you in advance
Use some fine wet and dry on something flat and sand the bottom of the valve cover until all the paint is gone.
