The Star and Garter / "The Star' July 2015
« on: 25 March, 2017, 15:12:04 »
Does anyone have a spare copy of 'The Star', July 2015 I think.  Apparently there is an article in it about the RAF WD B40s I wrote, but was not aware that it had been published?

I would really welcome a copy if there is one still available...   :)

The front cover is this one:

I am in the process of rebuilding the forks of my WD B40 and noticed that the fork damper tube socket screws had a sort of seal running length ways down a slot in threads.  I then came across a Service Sheet (thanks Julian) stating:

"To prevent oil leaks, fork damper tube socket screw No. 41-5138 is replaced by screw No. 97-2688.  The new part has a 'NyLoc' strip insert along the thread to prevent oil leaks".

Having searched for p/n 97-2688 on the Interweb I can't find anyone in the UK who lists this part, though one or two places list the older/original screw.  Does anyone know where they might get a couple of these later/modified screws?

Wow, looks good.

Who cleans the surroundings?

Ah you noticed that, I'm always being told my garage is too clean and tidy...  ;)

Always good to get the engine back in the frame during a rebuild   :)

The fuse, as mentioned, is to stop wires burning out in the event of a short circuit. So a 35A glass fuse is OK for that. It's what I have in my bikes.
You can get all sophisticated and have fuses for various circuits and relays for the headlight for example but that's not how they came out of the factory.
As an indicator of electrical sophistication, my 1951 Land Rover has just one fuse. The workshop manual states that in event of fuses blowing, fit a higher rated fuse. Things have moved on since then.

Thanks for that Star Twin, I find it so annoying to be 'electrically challenged'  :)

Hello Roy,

What bike is it & what is the part number?

Attached is a spreadsheet in excel format if you use the find function in excel & type in the part number or tank this may help you & hopefully other members of the forum.

Best Regards Mark

Hi Mark,

What models and period does the excel bolt list cover please?

You don't say what year your Thunderbolt is, but I found this pic of a 1964 Police Spec Thunderbolt:

Well that's a turn-up for the books...

Thanks for that Julian,

I have just measured the Plugs I have fitted and they are 1-3/16" across the flats, so I guess I have the larger/later version.  However, the BSA WD B40 Parts Book (revised 1973) I have still gives the part number of these Plugs as 41-5130 rather than the revised part number of 97-2708, but that's not unusual for the BSA/Army parts books.

So, I wonder if they introduced a new Tool/Spanner as well?

Edit: Just noticed that Draganfly list Tool 61-3003 as being 1-3/16" as well.  Hmm...

Well I wouldn't knock Draganfly as a firm as I've always had very good service from them, but the person I spoke to on this occasion certainly got it wrong.

When I contacted Draganfly Motorcycles asking if they had the Tool/Spanner p/n 61-3003 (as per that tool shown on the diagram) they said "no, that spanner is too small to fit the bottom fork plug..."

      For 12 volt my calc gives:

Boyer ignition - 21 Watt max (that's at fault level)
Coil                 -50 Watt
Headlight        - 60/55 Watt max
Stop/Tail light -21/5 Watt
Indicators       - 23 Watt each
Pilot Lights     - 4 Watt x 2
Speedo/Rev    - 2.2 Watt each

Total max 194.4 Watts. Assume horn and stop light straight from battery without fuse.

194.4Watt/12volts = 16.2 amps.. Maybe

And don't forget the Blue Flashing Light!

You would think that someone like BBB would supply a harness for a specific motorcycle model to the correct specification?

The part number for the tool you are looking for is 61-3003. I bought mine from Lighting Spares some while ago. I would try asking Draganfly if they have one because they bought all the stock when Lightning Spares closed down. C&D Autos might also be worth a try.

Thanks Trev,

However the part number you quote is for the tool for the Top Fork Nuts, not the Bottom Plug.
