im a budget racer so when i put money in my bike its kind of a big deal for me. anyway ive got about 3k saved up and im not sure where to spend it. my bike is an 03 gsxr 1000. ive got everything i need to do the 06 head swap so i will for sure be doing that. ive got a full m4 exhaust and pc3 already for it too. should i do an all out race head? or a 3 mill kit? and can you even do a 3 mill kit with a stock top end? i also will only be running a race gas. not sure which one yet i havnt talked with the local builder yet because its pretty hard to get him on the phone. it will never see the street either. so are there any suggestions? also im never going to run no2.
