Boyer Bransden every time Mike.
My A65T had an old one fitted when I bought it 14 years ago and has never let me down. I will be fitting one to my Royal Star this winter.

Great Tip Shedman, Can I use this in The Star?

Just change the 'tax class' in the blue section 7 on the V5C to HISTORIC sign it and take it to the PO. They will record it there and then, and provided its insured, tell you it is licensed from the beginning of the month. They will send the V5C off to the DVLA and you will get an updated one within about 6 weeks.
Then you can ride off into the sunset fully road legal, provided it is 'Roadworthy' of course.

I would recommend Perfect Polishing Co. from Atherstone. Top quality kit and they have been around for years. Also, they are on the end of the phone if you need any advice and always happy to help. Phone 01827 717606 or visit website

Twins / Re: Misfire
« on: 16 May, 2018, 10:20:28 »
I may have the answer! Many years ago (20yrs I think) I was advised to disconnect the kill button on the RH Handlebar switch as vibration causes the contact to 'make' intermittently and cause a misfire at, guess what, high revs! (This advice came for a former Lucas employee).
This button is connected to the coil by a White/Yellow wire. From memory, this connects to the ignition circuit (White) under the tank where all the wires come out.
Assuming yours is wired up as per the wiring diagram, this may still be connected. If so, it should take 5 mins to locate and disconnect and then see if it cures the problem.
You may also find a White/Red coming out as well which I dont think was used for anything. Really, this switch it really is only needed for the indicators, so there is only a need for the Green/White, Green Red and Green/Yellow to be connected. You dont even need the white (live) connected to it.
Worth a try! Let us know how you get on.

Does the misfire happen on both or just one cylinder? If its the one then it could be the carb on that side. I've got a pair of Lightning carbs you are welcome to try if it helps. I don't know the condition of them as they were handed down to me from someone else, but maybe worth trying each one in turn to see if it makes any difference.
Send me an email on if that could be of help

Hi Nick,
I'm afraid the BSA Owners Club doesn't give valuations as a matter of policy. The way I check on a particular model's value is to keep an eye on ebay auctions  over a period of a few weeks and see what they actually sell for. This is as opposed to classified ads tell that you  what people would like for the machine, not what they sell for.
I check & compare what condition they are in and fairly quickly get a feel for what mine is worth at that time.
If it's a general condition report you are looking for then go along to a club night, North Staffs Branch meet at The Labour in Vain, Yarnfield nr Stone, 1st Tuesday and 3rd Thursday of the month so should be there day after tomorrow. Make yourself known and I'm sure someone there would be up for taking a look and giving some advice.


Twins / Re: A65 Forks Interesting Problem

Just a thought, you could try some antifreeze. I remember a motor repairer telling me that it has a fluorescent dye in it that will show up under an inspection lamp. This helps them check for leaks when underneath the car in a dark backstreet garage for instance. Just dont mistake it for your mug of tea!

Twins / Re: Rear brake issue.
« on: 13 May, 2018, 20:21:11 »
Yes you will need them. They are a bit weird shaped which makes the edges that slip over the brake shoe 'clip' on, a bit like its got shoulder pads! The idea is the shoes become fully floating so centralise automatically. Note I use the word 'idea' as it should work in theory. In practice?????
Have a dig around in your box of bits and see if you find something close. If not they are available at places like Kidderminster M/Cs

There is a very nice Spitfire in the BSA Showroom in this month's edition of The Star. 7650 inc delivery to anywhere in UK mainland.

The Star and Garter / Re: where is this bike
« on: 30 April, 2018, 11:39:29 »
Hi Terry,
Nothing comes up on the DVLA Vehicle check, so the bike is probably dead and buried or has provided much needed bits to other Bantams by now.
Judging by the Reg No. it was proabably sold new by Motorcycle Mart (Walsall) who was my local dealer when I were a lad as it were.

Twins / Re: Which Fuel ?
« on: 28 April, 2018, 17:09:37 »
I have run my A65 on super unleaded for the past 5 years with no ill effects. I know its more expensive than standard unleaded but it has a higher Octane rating so suits the 9.5:1 compression better. Also, some makes like Esso didnt used to and still may not use ethanol in this grade so less chance of gumming up etc.
Hope this helps

The Star and Garter / Re: Diamond jubilee year
« on: 25 April, 2018, 17:25:14 »
Hi John,
The Diamond Jubilee in 2012 was Her Majesty the Queen's Diamond Jubilee on the 4th June commemorating her 60 years on the throne.
The Open day in 2012 was 50 years of the Unit Twin and to celebrate the Her Majesty's Diamond Jubilee the open day theme included machines made in 1952.
Hope this helps.

Great! Well done Roy. Let me have a picture for The Star.

Twins / Re: A65 OIF Amal to frame clearance on Thunderbolt only.
« on: 17 April, 2018, 15:16:18 »
Yes, the bend in the main tube leaves little room for the carb and requires the slide and top cap to be fitted before fitting the carb to the manifold.
Re yours, firstly, the Throttle and Choke cables adjustments are mid cable and they go into the top cap in just a plain ferrule. Theres no room for the adjusters on the carb top cap. Even with that, the bend in the cables are pretty tight to get around the Head Steady bracket. I find its best to place the cables through the HS bracket that's welded on the frame either side of the big nut that the HS bolts to. Also, keep the cable well oiled as that bend is so tight, it can stick due to rainwater getting in at the adjuster and dripping down the cable. I recommend getting some of those mid cable rubber boots to fit over the adjusters to stop ingress of water. I bought some from Feked about two years ago - mmmmmmm..... must get round to fitting them sometime.........
Hope that helps!
