How much sag should the bike have and also im taking mine to the drag strip friday how should it be set up for that im thinking soft but no 100% sure anyone know?

Read through this guide Suspension Setup Guide - Sport Rider Magazine. For street I think most recommend 30-35mm and I don't know anything about drag strip setup.

How do you measure it or does the article tell you? I dont havr time to read it now because i am at work but i will read it later

This video will help and I'm pretty sure the article goes over it.

great vid.
