Broom? or Vroom? If it is vroom, drilling the holes by itself isn't going to make it go faster. My understanding is you must also alter the carb to adjust for the increased airflow or it is going to run like crap. Pehaps you know this already.

If you really want comments, I think you are ruining a perfectly good machine. Without any tweaks at all I can get my 2008 up to 70, sometimes as high as 75. How much faster do you need to go? Try doubling your revs before shifting for a week (shift into second around 15, third at 30 and fourth at 45) and you will "feel" like the bike is faster.

Just my two cents. If the thing does 90 after you screw with it, I'll bring mine over and you can ruin it, too.
