I'm thinking about racing the Ironman class for the SS300 next year. This will be my first BID race. I'm currently racing the AMRA series. I race a KTM 350XCFW. I have a 3+gal. tank for it. I'm wondering if I can or should prerun the course? Do I need a pit crew? I have a well set-up race trailer that I'm using now at the local races.
