Just finished my A65 restoration  and got 90% of my fasteners from South Essex Fasteners Ltd at Southend. 90% cheaper than BSA suppliers. I had to cut a couple of bolts down, no problem. They do UNF etc.
I just emailed my list to them and also got the sizes from Draganfly's parts list ( They are not all correct ). I just got four rocker studs with nuts and washers, about 2.   8) They will post or deliver FOC locally. Regards Colin

Hi Mike. I bought one for my A10, lovely bit of kit and the return was amazing. I only bought it to slow down wet sumping. Just rebuilt my A65 engine and the pump looked good so I left it. Still have a very good return. if my memory serves me the SRM pump was over 300 including insured postage. Regards.

Just had a good look at the threads with my magnifying glass and they are in fact Helicoil inserts in each corner. Obviously this was done by the previous owner who is now RIP. What is the best way forward now. I have no experience with Helicoils, were they made to replace the original thread ? Now I don't have a clue what size stud to put in. Thanks.

Update.. The Helicoils are M8 and I will be collecting the studs tomorrow, job done I hope. Easy trap to fall in.

Well I have tried every spare bolt I have in my box of many other restorations, none of these fit the four threads in my cylinder head. By the way the 4 threads look fine. It is frustrating parting with money with well known BSA people and the parts simply don't fit. Even the locking nuts with the last set of studs were so tight I could judge how tight they were. I have tried a 5/16" W bolt in the threads, don't fit ? At least the bike is running nice ( So far )  :'(

Twins / My restoration started today, yippee.

 This morning I completed the wiring on the Boyer and Dual Spark Coil. Grounded both plugs and got a really good spark. Filled up the fuel tank, tickled the new Amal and kicked it over. Had a strange noise from the head area, it sounded like a dogs squeaky toy expelling. This would seem to be the rocker cover gasket not sealing, this acted like a reed and caused the squeak as the back pressure built up inside the rocker cover. Anyway the old girl fired up and sounded really strong, very good oil return. Just needs fine tuning I hope. No smoke or rattles. Not bad as it has not run in around ten years. Just need to sort out the mysterious rocker cover stud problems which is subject of another ongoing thread. Thanks for all the wise advice of late. Colin.

Hopefully I will be a bigger pest on the Bantam D7 section in a few weeks

Thanks Mike. I wish I had the old studs which I could replace with new and loctite back in. My engine is now almost new so I don't want problems for the next owner.

Is that the coarse end or the fine end and who might sell them please. Certainly don't want to damage my newly rebuilt head. Thanks.

Just noticed Draganfly list them as 5/16 UNF / UNC 14-1623 ? I assume that my head is the one that came out of the factory in 1971-2.

This restoration is still fighting back. The four outside studs holding on the rocker cover are causing problems. I ordered a set of four studs from a well known BSA spares shop. These studs have a course thread one end and fine the other. The fine thread will wind into the head but are very sloppy. The coarse thread will wind in a bit, but feels like it will split the casting if force is applied. The first company described one of the threads as cycle thread ? I thought these bikes were UNF ?
I ordered another set of studs from another well known company and have exactly the same problem, in fact exactly the same studs. If I knew which thread was in the head I would be tempted to just  put four bolts on the rocker cover to hold it down. Can anyone help, two famous BSA shops can't. Thank you.

We learn every day. What was strange was the fact that the indicators still worked. Thanks again.

Sorted... There are two different codes for the green-brown wire, one is known as LGN Light Green Brown. I joined this to Green & Brown. Hence the flashing lights in my man cave. It is now as it should be for the next owner. Thanks for all replies.

My lights are on the right position on the ignition and I have wired up switch 11 which turns the lights on and off  ;D. I also have dip and main now. In fact every light works, the brake lights works, warning lights fine, ignition wires have power. MY PROBLEM  ??? The pilot and head light is flashing in tune with the flasher unit  :'(. It still does this with the indicators OFF. The back light is fine.
I can see that the white wire is the common live, so why is the flasher unit activating the front lights. I took the white off the flasher unit and the lights are all fine. I don't use indicators, but would sooner have it right for the next owner. It does also concern me that the flasher unit could do the same to the ignition or could it. Hope to fire up this restoration this weekend  :-\

Now it makes sense, very grateful. Are the parking lights supposed to be on all the time the ignition is on ?

Stuck an old Bandit battery on the OIF 1972. So far  ;D New Lucas Loom. New handlebar switches left and right, New flasher unit. New Lucas Ignition Switch.

Ignition on,
 I have an oil warning light, I also have a front and back parking light. Fitted a new Lucas flasher unit and I also have indicators working fine, when they flash the front parking pilot light also flashes.
Brake lights OK. I have power to Boyer.

Ignition and lights on.
Rear light OK, pilot OK, no headlights, brake lights both ok. Power to Boyer.

I am working from the BSA A65 ( 1971-1972 ) wiring diagram. G21

I found this too small to concentrate on with my old eyes, fortunately my daughter has blown up the diagram on a good copier. Which makes life easier.

Questions. Should parking lights be on all the time with ignition on ? What does switch listed as 11 actually do please, it is shown as being connected to a blue wire which goes to switch 15.

Electrics obviously not me strongest point. Thanks.
