I'm intending to put together a hardtail custom next year, general idea so far is something with a 2" stretch on the down tubes, springer front end and I want to base it around the Sporster engine; but here's the difficult part - I want a 4 speed box with kick start and a magneto ignition system. I'm currently looking, on ebay, etc, for an Ironhead but I don't have enough knowledge as to which varient would be most suitable, anyone out there who's done a similar project or has any advice, I'd welcome their input.
