YZ10 rims - to drill or not to drill?

[kaszal]

I've got some JC Racing YZ-10 wheels for my Procat. Is it worth drilling the extra pair of holes in the rims or is two enough? I also wondered why there were only 2 holes if the wheel fitment had four screws? Thanks for any comments.

Just my 2 pennies worth, I ran my YZ10 last year and thro, a winter series
with two holes. That was on brushed motors 10 and 11 turns, just check them
after every run
