My 10 year old son wants to race for the first time on his XR100 this weekend and I was wondering if anyone had some quick mods. for the bike. It is an 03' and only have a few hours on it. The track already said he could enter the 60cc class and we went to practice last night on the track and I think he is ready to get his feet wet and maybe move up to a 2 stroker in the spring. Any help would be great.
