I have gotten some great help from all of you in getting one more out of our kx-60.I was building a 90 cr-80 but that was turning into a money pit.I would like to start looking for his next bike now.We ride mostly pits,open trails etc.I was thinking of a kx-80 or 100 and moving the power band down low.Also,anyone have experience with the polini 65?Thanks,ACES 2
