Type the following number into ebay and I think this is what you are looking for you could contact the seller and make him an offer to take it off the auction. 201915096291

You do not say wether the A7 is plunger or swinging arm. According to my parts book the swinging arm plate is called "clutch actuating cap"and is part number 42-3056. If it is a plunger model  then it is called "clutch spring plate" and is part number 67-3245. both are six spring clutches and with different part numbers I would suspect that they are not interchangeable.

I have been told that a chaingaurd is required for the MOT but have seen plenty of bikes without them if you are not sure give the MOT testing station that you are going to use a ring.

It is about 6 years since I had a bike inspected by the DVLA at that time the inspection only took about 10 minutes they are basically just confirming that all the info that you have provided is correct and the bike is what it is supposed to be, they will check that the frame and engine numbers are as stated on your application and if you provided photos of the bike that they match  the bike being inspected. At the time I was reclaiming the original registration and had submitted all the relevant documentation ie photos of both sides of the bike BSA dating certificate, MOT certificate and the completed relevant form I believe it was form V/55. they had also recieved info from the BSA dating officer. Because the MOT had been issued on the frame number  when they sent me the Tax disc which is now not required they also sent me a new MOT with the reclaimed registration.

I have inline filters fitted to both my A7 swinging arm model and my 1963 A65 both are connected to the return side with no problems. I sold my last 1957 A10 about 3-4 years ago and it had an inline filter fitted for the 16 years that I had it and I met the person who I sold it to last year and it is still running Ok. I always belived that they should be fitted to the return side of the pump.

Ihave a1963 A65 and converted to electronic ignition using the Pazon system and have no regrets also changed to 12 volts but with the pazon system you are advised to use 6 volt coils.

I would think that it would be the same as my 1963 A65 which has the BSA winged badge fitted to either side and that is all, I have seen some bikes with white coach line painted around the inside of the raised ridge but I don,t think that was original factory spec.

Twins / Re: A65 Early clutch changes

Just an update the new clutch center arrived and everything went back together OK checking with the old one the only differences are the shoulder is narrower to accomodate the thrust washer and the 4 holes which are approx 2mm dia in the recessesed part of the clutch center have been left out. This all came about because I had to ft a new alternator the hardest part of the whole job was feeding the alternator wires through the back of the primary case the hole is just not large enough to get the 2 wires through with the outer sheath covering the wires I had to cut the outer sheath back with shrink cable. I also had to cut one of the bullit connecters off as there was not enough room to get both through the hole together.

I have stripped the clutch down today and have found that my bike has the thrust washer 68-3245 already fitted bit surprised really as it is not listed on the original 1962-63 parts list and as I have said before my bike left the factory in October 1962 although a 1963 model. So I have ordered a later clutch sleeve and have the other thrust washer to hand so will update when it arrives, I suspect it will only difffer in the thickness shoulder where the thrust washer fits. If it was not so hard it would have been possible to machine the existing clutch sleeve to accommodate the other thrust washer. Incidently I can't find any parts list that shows just the one thrust washer fitted.

Thanks for that info Julian, although my bike is a 1963 model with the rod operated rear brake as opposed to the 1962 cable operation it left the factory in October 1962 but was not first registered until June 1963. The original parts list which I have for 1962-63 models does not list either 68-3253 or 68-3245 shims and the clutch sleeve is part 68-3212,I have a later parts list that shows all the 3 amended parts both shims 68-3253 and 68-3245 and the sleeve is 68-3252. I am at present awaiting a new alternator as one of the holding bolts for the aternator broke and has now damged the present alternator the insulation is breaking up altough it still works I am going to replace it and strip the clutch down and look at the components with a view to doing the changes mentioned.

Twins / A65 Early clutch changes
« on: 27 February, 2017, 09:33:05 »
I have an early A65 1963 and the clutch has quite a bit of side play and I notice that a few years later they fitted the clutch shims. I was wondering if they were introduced to take up the side play, looking at both parts lists it would seem that to update my clutch I would have to buy part numbers  68-3253  68-3252  and 68-3245 is there any thing else I would need to consider before going any further. Is what I am considering possible as also the clutch is quite noisy and maybe think the side play is responsible I did fit new rollers a couple of years ago which did not cure the noise.

Arthur is correct about valve seat reccession but it is not something that happens quickly. When unleaded petrol came in I owned an A10 Gold Flash at the time and was concerned about the possible effect on the valve seats so having a spare head at the time I ran the bike without any additive for a year took the head off and checked there was no reccession, but I did start to use the additive Castrol valvoline and still do,not sure if it makes any difference but a bottle lasts me at least 2 years you only add 1ml per litre of petrol maybe I am being over cautious. The advised test at the time was to set your valve clearances then check at 500 miles then 1000 miles and finally at 1500 miles if no reduction in the clearances then your engine was OK to run on unleaded.  I only use the additive in my A7 because it has no seperate valve seats I do not use it in my A65 and in the last 5 years I have not noticed any problems.

I wouldn't get to hung up about fuel if you take out the big players Esso and BP there are still a vast number of different forecourt names out there and to the best of my knowledge including the supermarkets none of them own a refinery so it stands to reason that that a good many of them will be getting their fuel from the same refinery. I do however think that the main concern is Ethanol at the moment it is between 5 and 7.5 percent maybe as high as 10 percent but I remember reading somewhere that if it went to 10 percent or higher under EU rules it has to be labelled on the pumps in America it is 15 percent.

Twins / Re: Oil Level
« on: 17 February, 2017, 19:09:34 »
Looking at the primary case where the bulge is at the front there are 3 larger fixing bolts the smaller bolt next to the bottom larger bolt is the level screw miss the next one along the bottom then the next one is the drain screw. Having said that I tend not to go off the level screw as it is dependant on the bike being on level ground, the best thing to do is to drain any oil out that is in the case then measure the correct amount and refill the case. The correct amount for your bike is 225cc or 0.4 of a pint,you should also have fibre washers fitted on those 2 bolts to stop any leaks.

This problem with the clutch basket being difficult to turn when tightened up reminds me of the same problem that I had some years ago on my early A65 which does not have the thrust washer fitted this came in later, It turned out that some of the new rollers were a few thou longer than the originals which caused the basket to tighten up I had to buy another set of rollers and measure each one to make sure they were the correct length they all looked the same but it was only a few thou that made all the difference.
