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
