I would like to know if anyone has put a 400 EXC on a scale with a full tank of gas? Also what is the horsepower rating, and easy hop ups. Why you ask? my Xr 400 is aging and the Wr 250 f doesnt have enough low end and has shall we say some nasty starting habits. The 520 is too much and I feel I could ride the 400 faster longer. So far I like the light weight, no linkage, UDS forks, E button etc.
