RE: Pipe Setup Question
This is a first stage of my modifications
I raised the case exhaust port, this was to uncover the port in the sleeve. It appeared to be a casting problem
I deburred the inlet port at the crank, a burr was protruding into the port
On the case I lowered a raised spot directly below the boost port. the pictures do not the changes well.
I filled the crank with JB weld and smoothed in the inlet side edges, and moved the rear edge back so it was not protruding in the case opening.
