I race in the 200/300cc 12-15 class and I was not sure if a 240 bore kit would allowed?And if so what do they cost?
Yes, 245stroker is correct. A 240 kit would be legal in the blaster class!!
in a 200cc -300cc class means 200cc 2 strokes and 300 cc 4 strokes, thats the ATVA santioned rules for a youth class, look it up
