Hey guys, I own a 400EX 2003, brand new and my friend just bought a fckn KFX400 but that **** is fast and I don't want 2 be beated by him when I'll race against him. Did anyone of u know (stock) if the Z/KFX is realy faster than me or not so much? I'm like 150pounds and he's like210pounds so do u think that this weight difference I'll beat him or I have 2 put a 440 kit on my 400 2 beat this damn liquid cooled KFX ???
Thanx!
