XR55, I looked at the water cooled muffler a little closer today.
I now see that at least part of the muffler is "double walled",
with the water flowing inside. I had some plugging, but managed
to blow sand all over the workbench!
Is it worth my time to pop the core plugs out of the muffler and exhaust
leg to check for further plugging?
Prepare to be boarded!
