OK, so I have never changed a sprocket on anything besides a bicycle before in my life. Like I stated before. I'm new to the whole riding scene. But I ordered a new front sprocket for the Rappy (dropped a tooth to 13), and it should be here tomorrow. I was wandering if anybody has any tips to possibly speed up the install process, or save me some heartache. Am I going to need any special tools? Thanks in advance everybody!
