FMF Fatty seems to work best on the yz85, milling the head helps to. It's hard to get good bottem end out this motor that has no power valve and is basically built for the intermediate rider, a 13/49 sprocket set up helps get it out the corners and off the line better to. A delta 2 reed valve and getting the jetting right on will help crisp up the bottom also. :cry: The rm 85 has the best bottom end power of all the minis, i have that the pc pipe on that mini really works good.
