Sorry I missed these questions when they were asked.Incredible!
1) Why the screws in the lower triple? I assume you want to limit the steering range for some reason?
2) Where do you get the vinyl to shoot the letters etc?
1. I had to trim some damage and removed a little of the tab on the lower triple, the screw replaced that gap and Yes I wanted to be adjustable so the handle bars are not so close to the tank at lock.
2. I have a small Roland plotter in my workshop as I custom paint helmets as well. www.graphixbyjim.com
