Harley just issued a service bulletin to the dealerships that changed the torque specs for the steering head on the SERG. The new spec addresses the increased weight distribution to the front end. Mine had the wobble at about 35 mph. It was particularly bad when front braking in a corner. My SERG is in the shop now for its 1000 mile service, and they will re torque the steering head. When I went to pick it up the voltage regulator failed during the test ride and there it sits in the shop, waiting for the new regulator. When the regulator failed I lost throttle control, most of the instruments, flickering head lights and voltage (indicated) went to zero. The shop tells me it was the regulator that failed, but in over thirty years of riding I've never had it happen before. I hope they're right, and the replacement is of better quality that the original part.
