The coating is Titanium nitride awesome stuff makes internals last for ever. Usually found on 4-$500 mills.
I do a timing change on my 5 ports that makes them more driveable on the bottom and give it more top end. Still has plenty of bottom to run in a truggy too. I only charge $15.00 to add it to a new motor and it can be changed back.
