  1. how much timing?

    Engine / Airbox / Exhaust / Fuel Delivery
    Hey everyone, I just got my factory pro adjustable ignition rotor, and was wondering how much timing I can SAFELY run? I'm about 500 ft. above sea level in RI. The bike have yoshi slip ons, and a dynojet jet kit. I think I can get away with running 5*, but wanted to know what everyone else was...
