I have to agree with him… and there really is never too much power, just use your thumb wisely. I have rode YFZ-450’s in the woods all day long and never really complained about the power. If you do woods riding, in my opnion the new Raptop 700 fuel injected is proably the sickest quad out. I rode a 400 with a big bore kit, it definatly helps, but nothing like these new quads. Good luck w/ your project.
