Would engine work on a RM125 like a 144 kit or something similar be able to widen the power band out to anything like a 250F? I have a 250F that I have been racing in Hare scrambles and like the power. I also have a 2000 RM125 that feels so much better to ride and is a lot lighter. It is just a little to hard to keep it revved up high enough all the times I need to. Any suggestions?
