just get in the list you should do some other stuff porting will to do very much
but if you must get the porting i would get tom morgan racing to do it he is claming he can get 4.3 hp on the crf450 for $605 if you get all his motor it will be like $2000 but he's claming 16hp also you may what to look at tc racing.
