first thing id do is look in the for sale section..... since u dont have a banshee yet, maybe u can find a whole 4 mil cub for sale ans then go from there. another ? have u ever rode a drag banshee ?? because u are making a big leap... not sayin u cant do it, just want to let u know its diffrent then just a bolt on shee or bolt on 4 stokes..
where do u live ? and what are u wanting to race on.. asphalt(1/8, 1/4 mile) , sand/dirt tracks (300ft).
