I need to change my rear brake rotor on my 90 VFR. I have the manual, all tools I should need, and decent mechanical ability, but I've never worked on bikes, just cars. I have a few questions. 1. How long should I budget for this? 2. Are there any tricks I should know? 3. I have a new axle nut, are there any other parts I should change while I have it apart? 4. I don't have a center stand. How should I supprt the bike to remove the rear axle? Did I miss anything else? Thanks Rich
