It can't be machined because it's hard to lock down. I had the problem with my 335. I was lucky, a friend of mine in NC has a shop and used this pretty cool he attached to a drill and worked all the hot spots out. It looked like cylinder honing tool except it was smaller with stone balls at the ends. The flywheel looked great and worked perfectly.
