Hello out there! New to the site and to the 4stroke world. Just recently purchased a 2012 Yz450f, I was looking for some suggestions to get a little more power out of the stock bike. I raced around a track this past weekend with a friend that rides an 2004 yz450f and when he took the 2012 out he came back and asked "where is the power" We both agreed that the low end needs a little more aggression! any ideas?
