Did a search to find help for more midrange on CR125, lots of topics for older CR's but nothing specific on current model (2005-2007) . I'm happy with topend but midrange should wake up little earlier, what to do? Thought of making next mods: V-force3, PC pipe&silencer, power now, decking cylinder base to achieve 1,0 mm squish, vertex piston, one tooth bigger rear spocket... Am I on right track with these? What else? .....btw Vertex has three type pistons; replica, race, pro race, what are differences between them?
