  1. Vance and Hines Cruzers, Now what?

    Engine / Exhaust / Cooling
    I just got done throwing on my Vance and hines Cruzers duals. The problem is now as i accelerate, it sounds great until i pull in the cluch to shift it backfires real bad and loud!!! Also when i engine brake. I'm assuming that means i need to adjust the carbs or something but i'm not sure what...
