I've always found my sprockets on ebay, and as already mentioned, Vortex makes good ones. I wouldn't change your gearing solely for wheelies though. If you lime the power and acceleration delivery with stock gearing, leave it and learn as is; any 10r comes up easy enough without a sprocket change. I've found that -1 up front feels best to me, however, I've never tried -1/+2 on my own bikes, but that's probably the most popular setup.
Install the rifleman insert with stock gearing and see how that feels before changing anything. You'll be surprised how different it feels with that shorter throttle throw. I also recommend that if you do decide to change gearing, start off with -1 and increase from there. Take it slow because gearing changes the power delivery drastically.
Strictly for the GEN2's
