i geared mine to 55/65(still running the stock 10" secondary) that along with a few other little things listed in my sig my sled feels like a whole different animal compared to the stock m7s i ride with. my sled is one of the quicker in my group when it comes to drag racing, which most people would not think an m7 could be good at, and we have all breeds. we do alot of tree riding and the extra oomph on the bottom end is great for on and off the throttle type ridng we do. i wouldn't hesitate to gear it down.
those running the lower gears and the 10.4" clutch how do you like it? i've thought about doing it for the extra belt contact but worry about getting it to low geared.
