Hey you guys. I have a 95' ZX7 and I can pop the front tire off the ground but i want to pull wheelies even easier. So i am gonna change my sprockets. My bike comes with a factory 16 teeth one in the front and a 44 teeth one in the rear. I want to put on a 13 toothe one on the front and a 50 toothe one in the rear to make it pop wheelies. My question is would i have to change my chain? My chain is a 530-110. Thanks for your time.
