Hi all. My first post. I'm a 59 year old with a YZ250 and a YZ400F. I've been working on my 400 to perform better on the trails (Pozo-La Panza in California). I just added a 10 oz. flywheel weight. It has a 51T rear sprocket and 14T front. I'd like 2nd to be just a hair lower. should I take a tooth off the front or??? YZ400: white bros. pipe, LE susp. mods, 14/51 gearing, 10 oz. flywheel weight, renthal ch & sprockets, bar, Acerbis hand guards. I'm strictly a careful rider - nothing too tough, but quite a few hills and some single track.
