How do you remove a governor on a dirt bike?

Most do not have a governor. If you are talking about a mini bike go to YouTube and type in preparing a box stock engine. They do it on video. There are four videos 1-4 that go over race prepping a 6.5hp engine for go kart racing. These are the same engines as used in Baja Heat, Warrior etc. If you have a 3hp minibike they have the same governor set up. You will take your max revs from 3600 to 6000rpm a big increase.
