Hi, I have a 1950 D1. Could anyone tell me please 1) if D1's had to have a front plate 2) if so was it mounted centrally on the front mudguard or 3) were there two plates mounted either side of the (deeply valanced) front mudguard? and where can I get 1950 dtyle plates made? 

Thanks

Hi Alan,

The deep valanced front mudguard on my 1950 D1, had the registration number painted on either side of the mudguard... Nick

Thanks. Not very conclusive! but I have seen a BSA brochure picture and the numbers are on the sides. Given 1950 rigids had deep valances it makes sense. Not sure but maybe 1950 plungers had the more modern front mudguards with insufficient room for the numbers, so they could have had the single mounting above the guard. 

Does anyone know if the numbers were always painted or if they were plates? Seems like a lot of trouble and expense to go to a signwriter!

Nowadays yes but then it would have been much easier to get it painted than get a plate made

after 53? for blade gaurds and even then they were common painted

If you are worried about the price, why not do the following. Get the number plate paint it white, then place stick on numbers and letters you require. Then paint it black, let it dry then remove letters and numbers,Use T-Cut to clean any imperfections. Mine looks alright.

I want to keep as original as possible so it now seems a single plate would not be appropriate. Now I know it should have reg on the valances I will find a suitable photo and ask a signwriter for a quote. Thanks for all assistance.

Thanks for this excellent photo. I assume there was some legislation regarding style and size of font so finding it is my next job.

Have a look at MoT regulations as you would probably have to comply with those :).

I had a 1950 D1 in 1953, it had black area on both sides of the valanced mudguard to receive the sign written numbers.

I have just restored an identical machine and a local signwriter with CAD kit set out the curved spacing and I fixed the whole sets perfectly aligned.

It was not very expensive. See photo

Hi

 

I was wondering if its possible to fit the above to the spline sticking out of the crankcase without having to remove the flywheel, and everything that entails. Does anyone have any experience of this?

 

Thanks

Alan

Found this in my inherited spares collection. Seems to be an electronic ignition module, there are some instructions with it but no branding. Is this one of Bantam John's modules?

I have been looking at these and wondering if they will work on the Bantam, or other two strokes, has anybody ever tried one?

It's a Rooster Booster Junior, also known as a Nova (see ebay). These have been discussed many times before, if you look ** Please log in to view ** you can see.

Unfortunately the RBJ's UK distributor is no longer with us, so they may not be available as a RBJ.

Nova is the trade name for these Coco, they were fitted to lawnmowers etc first.

I have a RB Junior fitted to my D7, it's a plastic box that measures about four inches by three inches by about 1.5, it has two lights on, a red and a green, a bit different to this which is basically like the Atom from Australia, just a power transistor I'm informed.

Four now on the road and at least several in bits.

@ lbayorkie

It could be one of Bantam John's but there are various examples from different sources.

@ Rev-it

Yes, they do work on non battery ignition Bantams but due to the multiple magnets in the flywheel may need to retain the points (no condenser) to prevent the unit burning out.

@ Mags 1

Your unit is not an RBJ (they are as above pictures and require no battery), you have an RB1 which is basically an amplifier unit which requires battery power to operate, similar in concept to the old Sparkrite units for cars. There is a much smaller unit available from ** Please log in to view **

I have purchased an indicator for my D1- but there's no bolt. I would prefer to have an original specification one, but does anyone know the OEM bolt size?

 

Thanks

So how will I know if mine can operate with or without points?

 

PS my Bantam is a 1950 D1 rigid.
