Get the part number off yours and look for one that matches on Pinwall. Personally I would stay away from Procom until they get the bugs out. If I need one I will either shell out the bucks for a new stock unit or go with a used one from a place like Pinwall.Engeland Moto is another option, they went the extra mile for me, great folks to deal with and honest. Prices were good too.
Click Me I was just looking at what they have right now and it doesn't look like any CDIs are available right now.
