I just picked up a 2000 XR100 for my son...It is his first dirtbike...He is 12 years old but a short kid. Right now the thing runs good as he does not need any more power at this level of learning...He has always had quads...He is coming off of a Suzuki LT80. I was watching him try it out the other day and he is very nervous on the bike but i know that will improve with time riding...I rode the bike a little and the thing to me felt completely gutless. Not like there is something wrong with it, just slow enough that if he had to climb a long kinda steep hill i dont think the bike could do it. I know he doesnt care yet but what can be done to improve the performance cheeply. thanks for all your suggestions ahead of time.
