[1badcrf]

Around how much do you guys think it will cost to build a crf im guessing around 15 said and done??But i dont know if i want to build one because i herd they might ban crfs from the nationals..dont know how true that is..do any of you guys know anything about this.... because if it is true iguess i could build a alum framed z for around 12???

Thanks in advance
