[QUOTE="James980, post: 28469, member: 16990"] I'm not sure of the specific displacement of the bike, but if it's 250cc or less, it must be run in Class 1 (the class for 86cc-125cc two-strokes). If its displacement is just over 250cc, then it must be run in Class 2 (the class for 126cc-250cc two-strokes). This is from the 2000 AMA amateur rule book, page 14. James 00CR250 [/QUOTE]
