    exhaust noise???

    I got a 750L I installed a Mac 4 into 1 exhaust,and did a Dynojet stage 3 jetting kit with open air cleaners. I have a cackling noise @ the colecter pipe when I speed up and let off gas to stop. Any ideas what could be causing this.

    You've probably got more tuning to do on your carb. Post this in the technical section and you'll get a lot more replies. Year of the bike would be helpful too.

      A ticking or cracking noise can also be leaky exhaust gaskets. Is the noise at the header/manifold connection or in the collector where the pipes join?

          Crackling on the overrun is an air leak into the exhaust, check and reseal all joints.
