Hey guys i need some input i have a 07 fatboy with rhinehart cross back a arlen ness air filter and a powercommander dyno tune im pushing 70hp with 80.44 touque. i wanted to get more horsepower i was thinking of getting new performance head and changing the cams. I really dont want to go to 103ci cause my dealer said it will only give 12 more horsepower and for 1300 i dont think its worth it. also what head and cams should i go with?
