All I needed was a deep 32mm socket. I removed all the stuff in the primary chain case without any special tools, then the inner cover to reveal two shattered cogs. I replaced these at a cost of £120 (sorry I'm in England!), now the sprag clutch has seized and the engine is driving the starter motor. A new sprag is £100 over here, so I have bought a blanking plate for £9.75p from Hitchcocks in Birmingham (England, not Alabama) to fill the hole when I remove all the electric starter gear, and just get used to kicking it. I do kick start most of the time anyway. This is a weakness and design fault in the Electra X because if the engine kicks back (and there's no manual advance or retard on this one so it will), then the sprag engages and forces the idler gear and driving cog backwards against the compression, often destroying these cogs in the process. The electric start on this model is really just a gimmick. It's as much use as the human appendix. It can only go wrong and cause grief. With these Enfields, they are easy to kick start when you know how. Plenty of demo's on youtube to show us how to do it easily.
