I have a Classic 1 and replaced the cap. It's really easy to do because VPI used wire nuts to terminate it. So you don't need to solder. I don't remember what value cap it was so ask VPI. I picked mine up from Radio Shack. After the cap change the pop was still there but very quiet and no longer a problem.
VPI has known about this problem for some time. I am surprised they have not just started using the higher value cap on their motors yet. It's such a simple and inexpensive fix.
