Could someone give me a ballpark for what RPM to set a clutch up for on a Clone? Our rules allow aftermarket filter,pipe, and rejetting the carb only. Clutch must be a shoe type (I will be running an Inferno Flame). I will mainly be running bullring type tracks, relatively "soft" dirt, low to medium bite. In what cases would you want to engage at higher/lower RPM? Thanks in advance.
