Hello all. I keep hitting the rev limiter at 5900-6000 RPM, no matter where the dial is set. I've swapped out the coil and the pickup, phased the rotor changed the cap, etc. I even thought that I might be experiencing valve float so I changed springs and retainers as well. Even with the rev limiter dial set to 0 (off), I hit the limiter at 5900-6000. Never had a problem like this with my old 6AL box. Help! I don't know where to go from here, except maybe buy a different box.
