With studding you should match the number of studs to the HP of the sled. I run 192 on my 800 that's pushing 150 HP, I just studded my friends Classic 500 last weekend with96 in the center in a V pattern and 6" carbides. As Triump stated I also mark it first with a paint pen and I use a template. The template I use only repeats the pattern 4 times across the track.
I have to disagree with Paulxlt, I have a 1" aggressor track and the 192 studs make a vast improvement in handling combined with 10" carbides.
Good luck, it doesn't very long, a few hours if you have an impact wrench to spin the nuts on.
