Case Port Matching
I am freshening the bottom end of my 2000 XC327, with a crank rebuild and new main bearings. I figure it may be worth doing some case cleanup while I have it apart. Does anyone have experience with cleaning up the GG cases for better flow/performance and is it worth it? If so, can you share some details.
The case transfer port areas are pretty rough and floor of the reed cage is uneven. I hear that it is bad to remove too much material from the cases because it increases volume and reduces the compression in the lower end of the engine. I started putting some Sharpie marks where I thought I would do some grinding and smoothing.
Any input would be welcome.
