Hi All,
Going back to the original question,
There are lots of shit sockets advertised as WW on the net, they are nowhere near accurately sized :o

Try and find proper WW size spanners and sockets from known brands
Search ebay, autojumbles and car boot sales for secondhand Britool, King Dick, Gordon and other UK / German brands

British Bikes / Re: JAP engine number
« on: November 30, 2018, 08:21:20 PM »
Hi Paul,
That about sounds right, if the engine fits in generally with a 1929 appearance,
twin port would be a style of the times
JAP offered several style options on basically the same engines, (different finning shapes and magneto chain case lengths and placements or maglita driven from the drive side)
The year codes ran from September to August according to my JAP book which can lead to "discussion" when it comes to Whats Vintage???

Remember that JAP reissued the engine year code post WW2
This is why lots of late industrial engines that appear for sale are mis described as "vintage"
Usually the SV engines from the earlier period had cylinder and head as one casting

Hi,
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
But!!
I have not seen anything like the rear mountings on a BSA before

British Bikes / Re: Anyone into Scotts here
« on: October 13, 2018, 05:24:23 PM »
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   ::) ::)

British Bikes / Re: anyone up for a good run out?
« on: September 29, 2018, 02:09:40 PM »
Hi,
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
http://www.britbike.com/forums/ubbthreads.php/forums/7/1/ariel-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 »
Hi,
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

British Bikes / Re: Villiers engine
« on: August 10, 2018, 12:01:02 PM »
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  ::)

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

« 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

Identify these bikes! / Re: Help identify Coventry Eagle, 1928 or 1929?
« on: August 04, 2018, 02:02:54 PM »
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 ,$,, 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
