Damn.

Went to check and set points gap today.
The locking nut stud came out of the backplate with the nut.

I took backplate off and was able to thread the stud back in.

The nut now tightens but not fully.
Feels like the stud is turning too

Can I lock it for now with an adhesive of some sort?
If so, what’s best.
Hitchcock’s are out of new backplates at the moment.

What a poorly made bit of kit!

Help!
So far I have: removed electric start, removed panniers and crash bars, fitted Lycette seat and short silencer, rejetted carb, fitted pancake filter, rebuilt kickstart mechanism, replaced snapped clutch cable, fitted Lucas stop light, fixed headlight short ....

Don’t Hitchcock’s do a repair kit for this problem?

Part number 92013. £13.80?

The problem is not the backplate but the thread in the alloy casting of the "distributor" body. As my learned friend points out, it's repairable, either with a helicoil or tapping out for an over-sized stud. Welcome to Indian metallurgy!

Thanks for the reply.

Is that the right thing for me?

Mine is the contact breaker lock nut.

These look like the advance retard plate locknuts.

Happy to stand corrected.

Mine is F on this picture
 It is a tiny threaded stud that seems to be crimped in the backplate
The condenser mount is the same type of thing

Sorry, I’ll have to bow to the greater knowledge of those owners whose bikes have points....my iron 350 has TCI ignition and therefore no distributor is fitted.

Like 'PaulW', my 2005 "twin" of yours has also had an electronic ignition of unknown type fitted by a previous owner, but in view of the low cost (under $13 delivered) of new complete contact breaker plate assemblies (see, for example: https://www.ebay.com/itm/Royal-Enfield-Bullet-Electra-500-350cc-Contact-Breaker-Point-Plate-12-V-141810/284213175493), I would simply replace it. Of course, while you're waiting for that slow boat to Brunei to arrive, a dab of Loctite Red (Permanent) or similar onto the screw's threads and/or a good tiny chisel mark or two across that screw and the back of the plate shown below, with perhaps just a dab or "schmear" of JB-Weld or similar epoxy or even the tiniest little spot weld or braising filed flat to help hold it might do the trick for awhile...Hell, maybe even forever.

So badass my Enfield's actually illegal  in India.

(Legal enough to pass muster if they don't look too closely in Woodbridge, Virginia, where the buses don't run at night, holidays or weekends and I'm a contender for 'Village Idiot')

If you want another points back plate (actually an Indian copy of the Lucas 4CA assembly used on mid-60's BSAs) from a UK supplier, Henry Price has them. 4th item down.

Otherwise, consider upgrading to a Pazon SureFire...

Locktite Red! Old DKW's were held together with it.

Looks like Paul W's found the kit:
PART No. 92013
REPAIR KIT FOR DISTRIBUTOR THREAD
It is very easy to strip the thread that holds the contact plate in your Bullet's distributor. This kit is the solution to this problem. It consists of: oversize tap and guide and 2 special replacement nuts. It is an easy repair for the home mechanic to make and can be carried out with the distributor in place.

This is just too easy. I'd fed ex it or ups & pay the extra. Right now it's optimally repairable. Goobering it full of Locktite may make later repairs a PIA...It'll probably be there in a week or less, eh?

You're not paying attention, AzCal!  ;D

WB corrected us at #4 in that the problem is with a stud on the backplate itself, NOT the alloy body of the "distributor" thingy as we previously thought.

I have never considered electronic ignition in the distributor to be an upgrade and all Bullets I have had on the road have used points. The crank mounted, self generating types we have on the two RE racers are, however, what I would consider to be an upgrade. The only road bike I have with electronic ignition is a Suzuki GT200X5, and that had it fitted at the factory.

From an ignition point of view, the PVL and Electrex World are self-generating and you don't have to worry about slop/lash in the timing gears causing timing fluctuations, so I can see an improvement on two fronts, especially for competition use.

Not so good for a roadster Bullet, however, as the only versions presently available with additional lighting coils, and which fit the Bullet, produce a rather feeble power output, 50-60W.

I'm with AzCal, Just run some solder into and over the back of it.
If you don't have the equipment or skill, an electronic repair shop, or a plumber will do it.
It's metal, it doesn't understand!

I rode my bsa with the mushroom distributor held by loctite blue for two years, if the thread has gone put some loctite on it and do it up as tight as you can with your fingers let it cure overnight, that will fix it as a temporary fix, that's just a way l know. Spray with brake cleaner first to get any oil off.
