There are none on mine and they have been fitted for 13 years without problems. I would ignore them.

Hi James,
The Rover K series engine have the 'coil packs' which are the same kind of thing under the plastic cover on top of the engine and it must get pretty hot in there so it will probably be OK. However, a quick email to Pazon might be a good idea.

Whoa Mike! I ordered a set from SRM for my OIF A65 (different part no. to the pre 1970). They only do the Colsibro ones and they cost about 23 each - yes nearly 100 for a set of guides. Anyway after 2 weeks, they were no where near being done. I spoke to the workshop and they said they were chokka blok with work and couldn't tell me when they would be done so sadly I cancelled.
I got some from Autocycle Engineering, Phosphor Bronze at 13.50 each +Vat British Made. Mind you these are standard not oversize so I'm not sure if they do oversize ones but definitely worth a try. 01384 253030.

Sorry Bob, I was referring to the previous post. Actually, I wanted to point out how easy it is, if not already done, to get the taxation class changed to historic vehicle.

Assuming that they aren't bent, (they don't look so in the picture, I would just get anyone with welding equipment to fill and dress the dents. If you make up a sidestand bracket, they can weld this on at the same time.
The wear is probably from the bash plate which has gradually worn the legs away over time.

Twins / Re: '71 A65 lightning running rough

Sounds like a weak mixture on one of the carbs on Pilot stage (first 1/8) of throttle). As you say it runs well whilst accelerating which singles out the pilot stage being the problem.
Despite ultrasonic cleaning, I would remove the offending carb and check the pilot bypass (the two small holes in the bottom of the choke bore, either side of the front of the slide, by squirting carb cleaner down one side and seeing if it comes out of the other. if it does, poke some copper stranded cable down them. I had to do this on my Thunderbolt a couple of years ago and it worked a treat.

I concur, I have an 1955 Ariel Red Hunter (almost a BSA) which is a long term project and it has a V5C but as it's been a wreck or in bits for many years, the taxation class was 'not licensed'. I tried to get it changed to Historic Vehicle class a couple of years ago and was told it would need an MOT first. Nowadays of course it is MOT exempt so I downloaded and filled in the V112, amended the taxation class in the box at the bottom on the V5C to Historic Vehicle Class, signed and dated and have just taken it to the Post Office and guess what it's now licensed as Historic Vehicle and I will receive a new V5C with 6 weeks. So I could go out for a ride on it, but hang on, its still in bits so perhaps not quite roadworthy yet.
Anyway, so, if anyone out there has a pre 1960 bike with a V5C but the taxation class is other than Historic, get it changed before the 20th May to save lots of hassle!

The Star and Garter / Re: Classic British

There are quite a lot of 'pop up' classic spares shops usually found on ebay. Some of them are asian guys, like the one I used in Walsall (different address) from which I got excellent service. (The text used in the T's & C's and about us sections are usually a give away)
These guys tend to sell a lot of Indian sourced parts as they have contacts there. Hence like me, you can get a pattern speedo drive gearbox for 10 including postage so 7.50 and they are making a profit on that!
The phone no. is a Birmingham no. so that will be their warehouse/lockup. The address will be the guys house (the one I used actually lived in the same road I grew up in).
You pays your money and takes your chance as they say!

Twins / Re: SRM A10 650 twin

Re your questions regarding oil. On SRM recommendation, I have used straight grade SAE 50 in my Thunderbolt for the last 10 years (changing it regularly of course). In that time it has done 13000 miles and I have just checked the bores and big ends and they are showing no signs of wear.  I do have a remote screw on cartridge oil filter fitted, which must have helped. I use Morris's Golden Film available from all good Motor Factors. Main thing is to be sensible with the oil changes. Some people change it every year without fail but if you've only done 500 miles, that's a bit over the top in my book. Mine has been changed approx every 1500-2000 miles, dpending on how much I've put in during that period (A65's do tend to use oil usually via the valve guides). Other recommendations re Gearbox and primary chaincase are correct.
Re the Anti Syphon valves well, the jury has been out on these for years. The A10 does have a check valve in the oil feed internal galleries which, I believe is the usual ball and spring but is got at from inside the crankcase so not easy to sort out if it doesn't hold the black stuff back. I would assume that SRM would have re-seated this as part of the rebuild, so I suggest you try it and see. The beauty of the SRM sump plate is the drain plug. If you have left it standing for a couple of weeks, undo the drain plug and see how much comes out. If you use the bike weekly, its unlikely that much will have got past the 'overhauled' oil pump anyway'.
Hope this helps!!

Twins / Re: Rare grommet OIF A65
« on: 02 March, 2018, 13:05:27 »
4.50 each!!!!! Crikey, someone is taking the rise!
These are the sort of product stuck in the end of Tubular furniture. Take a look at They do these in Black, grey or white and a 22mm ones for example is 31 pence each including vat. OK, they are not rubber, but are durable and will do the job!
I have got some on the Thunderbolt. I had a scary moment last year when I came to remove the cover, I found black grommets in the holes. Now I have never fitted any of these in the 13 years of ownership so I thought I was going mad!! I then read in the Wiltshire Branch notes that Pete (Wiltshire Branch Chairman) had been to Popham Megameet and whilst there purchased some of the grommets for his own Lightning. As he bought a bag of 10 for pennies, he kindly adorned 2 other OIF machines with some. Mine was one of those lucky machines. Phew! I cancelled the appointment with the Psychiatrist with great relief!

I believe the ULEZ charges don't apply to Historic vehicles.

Didn't you mean to say it switches from Pilot to Headlight?

Thanks Julian,
I have to admit I have never studied the T65 spec as just thought of it as a Triumph. Also, to my shame, I never read the guff on that in detail probably for the same reason, or being close to the end of the book, fatigue had set in! ;D

Looks like Crofty has a T65 which must be quite rare!

Sorry I should have acknowledged the source of the picture was from 'BSA A50/A65 Twins All models 1962-1972' by Roy Bacon ref Niton Publishing, Isle of Wight.
