Here's a running video.
That oil pump was definitely blocked inside the casting..
Got another on order.
So the oil pump was not flowing. Took it off and the outlet was block. Removed the hose tail and I drilled the smaller bore. Oil now flows through.
Without taking the pump alart again I am unsure if I have drilled too deep and the oil is bypass internally. By blowing through it and operating the throttle.. it doesn't seem to flow more or less on throttle position. Does there need to be drive to the pump and is it a variable gear inside is what changes the flow?
So going to have to inspect.
Or compare to another.
Also bike cuts out when put into gear with stand up or down.. I think it's a faulty sidestand switch
A few little things to sort
Anyway.. a few pics
@NINJA yes, this engine had a fair few leaks I sorted today
Gear lever seal
Also putting the water pump pipe back in caused many problems, took so many attempts to get it to seal.
But now have a fully functioning to 2stroke pump .. as it was from the factory.
