hey guys... i'm curious... i live in the boston, MA area and was looking around for a good place to bring my bike in for a dyno run... anyone ever heard of ACS Racing in hanover, MA?... how do dyno's usually work?... do you guys usually leave your bike overnight?... i was under the assumption that you bring your bike in, have them run it on the dyno for a few hours, and they fix your A/F ratio etc... then you're off... i've never heard of anyone leaving their bikes overnight to have it dynoed... any advice? thoughts?
