RE: sprocket coversion
Changing the front sprocket was super easy. 3 bolts and the cover and sprocket are off. -1 in the front = +3 in the rear. so changing the front helps keep the stock look vs a huge rear sprocket. Unless you want a rear pizza size sprocket.... so -1/+2 = +5 in the rear and keeping a pretty stock look.

RE: sprocket coversion
I've done several conversions now, and I prefer not to go down on the front. It seems like more vibration when I do. IF you goto a 50 tooth on the rear you will have plenty of torque, and top speed will be at least 130 as I had mine to 128(GPS'd) the other day and it was still climbing. There is a sprocket conversion calculator if you do a google search. It will explain the ratios better. Also I like to stick with the 525 chain on a stunt bike. I tore the hell out ofa 520 setup.
