When my 05 450 was bone stock, except for 10 paddle tire and 13/49 gearing, I could pull 4th and then downshift to 3 at the top. I used to weigh 190. Now that I lost ten pounds, put the yfz450 quad's exhaust cam in, and a full drd exhaust and became a much better rider, I bet I can pull 4th the whole way.

Yes, my bike was fairly close to be jetted right. Jetting makes all the difference in the world.
