Hi, it's my first post here, first of all i' m italian so excuse me for my really bad english. I have got a 2004 Cr125 and i want a bike with more lower at lower rpm, cause now i use it in enduro/woods riding.... There are differences between a V-Force 2 reed valve and the V-Force 3? A boyesen, or a rad valve have more power at higher RPMs? Thanks!
