Restore it correctly. If you would like a chopper I can hook you up with someone who has plenty of salvage bikes that probably won't ever get restored, they would make good choppers. To build a chopper you pull much of the stock stuff off of a bike and toss it out, including the frame and forks and wheels. Why destroy a good original that has sentimental value to you, when you can start with something else that would be really hard and expensive to restore correctly...
