- A Sportster isn't a Shovelhead, but known as an Ironhead. Shovlehead is a Big Twin engine. Unless you have a Shovester, which is a Sporty bottom with a Shovel grafted on top.Have you checked to see if you have spark? Something easy to try is to swap the plug wires at the coil end only. If the rear cylinder quits firing, then you've got either a bad coil, or a bad plug wire. Coil, plug wires, plugs. It's just about gotta be one of those three.

RE: performance
Slugger,
Good advice from above, if you are getting spark or it's not the plug, or coil you might want to do a compression check, just in case something happened to the fresh rebuild, ie broke valve spring etc. Keep us informed to what you find.
Good Luck

I don't have anything handy to tell you how to check your mag. Drop by this site and e-mail, whatever, this guy. Buck's a magneto guru.
