A side on photo should help id the tank
The fliptop filler cap and breather in front of it suggest ZB BSA GS,
the front mountings that take the rubber inserts also fit
I have not seen anything like the rear mountings on a BSA before

Hi All,
For those interested the Scott and sundry S7 bits made £6,000
The BMW went to £26,000  :o :o ::) ::)
The Matchless made £12,000,
I thought the Matchless would have made a bit more ??? taking into account the value of the Vincent front end ??

Hi m-m,
Are you trying to throw us off the scent so to speak?  ;D
The Scott and S7 are lot 420

The Matchless with Vincent forks and the BMW in the previous lots should be more in demand ??

Hi All,
Going OT here somewhat
Allegedly the quick and dirty way to tell a JAP bike engine from one from an industrial engine is the bike crankshaft will have a tapered crankshaft for the drive while the industrial unit will have a parallel keyed shaft.

Not always the case,
Usually industrial engines will show some evidence of a cooling fan or shroud mountings and quite a lot have either extended crank or cam shafts to drive the cooling fan or for a starting handle

I visited the so called "National motorcycle museum" in USA a couple of weeks age where I saw a JAP 600 industrial engine labelled "JAP from the Teens", (it was more than likely ex Howard Gem rotovator as it was identical to one I have) .. The person in charge was happy to take note of the correction I offered   ::) ::)

It wasn't the adjustable mag sprocket that gave trouble, even thought it was blamed initially, the points rotor screw
came loose and the rotor pressed key "unpressed" to let the rotor slip,
It became apparent quickly that evening after the original sprocket was refitted when the bike fired up and died almost immediately with no spark,

,just making sure nothing comes undone or falls off........

That's the lesson learned by the owner /rider   ::) ::)

Hi All,
I am just back home in Ireland after spending the last 3 + weeks in the USA on the Cannonball event
I was there as mechanic and driver of the service van on behalf of two riders, one of whom rode the black Ariel
The second rider had a 23 HD model F (magneto ignition J) that I had mechanically rebuilt over the last year
Unfortunately the HD rider fell ill and was not able to complete many miles
The Ariel rider/ re builder wrote a very long and detailed blog of the rebuild on Britbike forum
The Ariel suffered a few (mostly simply repaired) problems but got to the finish in one piece  ;D
The main problem encountered was when the Ariel lost compression  (exhaust tappet kept tightening up), The exhaust valve seat in the head was recessing and the guide wore badly  :(
A Norton 16H guide "borrowed" from Team Norton luckily had the correct ID and OD but had a large shouldered section, I turned this down using Team Nortons mini lathe, also polished up the valve for reuse
Another team provided a Neway valve seat cutting kit and the seating got a severe cutting
It really needed a new seat, but needs must
Opinion was that as an oil ring was fitted to the new piston no lubrication was getting to the guide, even though 2 stroke oil was being added to the fuel ????????
I'm not sure I go along with that theory !!

The Norton Team did really well and only one rider dropped some few points
I was delighted to see the 3 flat tank Triumphs did so well (models H, P and N)
The model H had been converted to chain drive using some massive sprockets and a tensioning gadget

The Brough SS100 suffered guide/seat wear the same as the Ariel, and a broken fork

The overall winner rode a HD single  8)


Japanese Bikes / Re: Mystery clutch?
« on: August 23, 2018, 10:15:54 PM »
Clever looking mod  :D
Suzuki GSX (R) 's from the Eighties early ninety's used solid clutch outer drums with that tooth profile
What diameter is the outside of the drum,
I bought a few Suzi clutches on fleabay with the intention of making a replacement clutch similar to the Pearson BSA
so could measure for comparison if you need to

Hi Ken,
Thanks for the lathe photo,
Its a fine looking machine,
I used to have a Woodhouse and Mitchell (Junior 7) but traded that and got a Harrison 165, a bit sorry I did that  :(
I also have a Colchester Triumph 2000 short bed

It looks like the Villiers was cut down to make a power unit to drive some machine or other
That was a very common thing to happen back in time  ::)

Cannot help with the Villiers but can you tell us a little (or post some pics) about the fine looking lathe in the backround?

Hi All,
The chrome tubing was robbed from all the payphones  :o

« on: August 04, 2018, 09:09:59 PM »
Hi Ian,
If you shorten the slide to reduce the cutaway the needle clip position will need to be moved the same amount
(if you have enough grooves to compensate)
Filing the intake side only will increase the cutaway, the opposite of what you want to do

Hi Micke,
I know the big v twins with the external plates bolted to the cast in rocker pillars are referreed to as "dog ear"
But I would have always considered the engine in the linked pic as a dog ear,
Anyway what I wrote earlier still stands, mucho £,$,Ä, SEK  !!!
That is the type of engine for sale in the link I gave you, (not sure id single port?)
I have not seen another one for sale in 30 years!!!

Some years ago I found such a head and remembered that there was someone on this forum looking for one
I put it with the rest of an early 30's 350 engine and sold it to the advertiser

You need to source a lot more parts for the project bike, do not get hung up on finding the engine parts, but work with what you have and get the bike completed, blank off the left exhaust port if you only want to fit a single pipe.
There is no point is chasing an image in a photo of someone else's bike, without strong proof how do you know what was supplied 90 years ago
Catalogs were only a guide, production by small manufacturers (especially)varied quite a lot from the catalog images

Hi Micke,
if anyone is selling a top without the rocker cover, Iím buying it

I think you mean the "dog ear" type head ?
They are rare and very expensive
Pete's bike's had a complete engine at Stafford in April.

I would not it it worry me about the engine date, the J.A.P 1929 year production started in August /September 1928
Who knows what CE threw together for export ::) ::)


British Bikes / Re: Cush drive , necessary or not
« on: August 03, 2018, 08:31:42 PM »
Hi All,
A major consideration when adding an electric leg to old brit iron is the quality (cranking amps) of the battery
Look at, and note the battery used
A proper battery will give a couple of hundred starts without recharging  8)
The Alton starter fitted to Vincents needs this battery to work even using the valve lifter

A friend who has had two new hips has fitted a Honda car starter to his vintage black Ariel  :o
He fitted a ring gear to the back of the clutch and fitted the starter behind the gearbox
Total loss battery (PC680) but it lasts for months between charges

Rex is correct, you need a 12v regulator, I have converted several dynamo's to 12v
You can also get a 6v dynamo to charge a 12v battery with a suitable regulator, it needs to spin faster than a converted one to start charging though
A 6v regulator would not charge a 12 v battery
When buying the suggested DVR2 you need to specify that its a converted dynamo

Supplier of parts said regulator cutout should be ok

That statement is complete rubbish,
