hello i was just wondering does any one have a good setup idea for the topend lowend needles? if not its cool. also can you wash the air filter? or you need a new one mine is getting a little dirty. also my last question for now is do i have to adjust the trasmission screws? i dont really like to play with screws liek that casue if they get to loose they will get lost and pop out or something like that. any help would be good .
