I dont know why I dont hear too much about the 3 port, man they are awesome. I have 1 on the way. They are super sick and they have that awesome newer designed head plus the 3 has the newest designed internals out of the 3 race mills. I will have it modded and use it along with my PTM 5 as a tuning option I cant wait to try it and from what I hear it is the easiest of the 3 to break in. I just want to see an awesome mill get some of the limelight like it deserves. I ran a stock 1 and it was so smooth I am just addicted to modding my mills to get the most out of them but there really is no need to. And about the parts availibility, Russel told me he is workin on things so just be patient guys.
