we have a 90 honda that my son would like to race he is 10 years old, it is an 04 model. We went to a hair scramble, and he got third place out of 6 riders, all 2 strokes with alot of mods, he was wore out after the 20 miles and the bike was really out of place, the tires were wrong and the susp. also lacked alot. We dont want to spend alot of money because this is all new to us , and my experience is that sometimes you take the fun out of things by trying to make it better, we just dont have the connections to get the help we need . please help .
