I have a 08 Ultra that is stock except for Xied's and some chrome. I am 6 ft 280 lbs and misses is full figured. I tow a trailer that weighs 85 lbs empty and probably only put under 100 lbs of gear in it. The problem I am having is pulling out from a dead stop especially on a grade. I know bike is maxed with weight and trailer but it drives fine going down the road. Is there anything I can do to lower the gearing especially first gear as it seems tall even without the extra weight. Never had this problem with 1340 motor and 5 speed so I guess it was geared lower. Any thoughts?
