Hi Rex,
I don't think so, look at the hands

Hi Leon,
Yes I had seen that photo, I have a Chater Lea "watch" on eBay
its mostly bicycle stuff that shows up but you never know??

What about those handlebars?  :o
They look really "oversize" but its hard to gauge as the CL bikes are really small in stature

Hi All
Thanks to Keith, I now am in possession of a spare Chater Lea hub and  Moss gear lever
The gear levers being alloy are prone to accident damage, I have one or two "shortened"  :( levers so glad to have a full length one spare
It goes to show how the internet and forums like this have made Worldwide communications so easy

Regards

Hi ALl,
Devon rim co sell two ranges of rims, "Valtru" the "trade" quality and "Rolltru" the premium quality rims
The rims I bought must be the premium product as they are the doggy's dooda's ;D

Hi Mossy,
OK
So we need another photo of the rear view
Smaller resolution would help too

BSA and Triumph clutches look more or less the same in photos
The inner drum should revolve in the outer drum
It should push out easily from the back and drop the rollers everywhere   :o  ::)
Try an ordinary  1/4 x26tpi nut on the spring studs, if it fits ok then its the new spring nuts are the problem
Some of these type clutches the spring studs thread into the inner drum rear and are peened over at the back
These are one use only parts

Hi Mossy
Can you post some photos?
One pic is worth a thousand words

Hi All
Originally they were 3/8 x26 as suggested

(Goldie and the other alloy headed pre unit singles engines are 7/16 x 20)

Hi,
Not too familiar with C15's but on the pre unit BSA's the tab bends over a flat on the hub
My opinion is that the lock washers are a waste of time,
A spot of thread locking fluid on degreased threads is a better solution
If they had Loctite back then they would have used it

Hi ALl,
When I opened the link to an ebay ad on the "What do I have" thread  this appeared in the linked pages

http://www.ebay.co.uk/itm/1927-Motobecane-MB2-Vintage-Genuine-Board-Track-Racer/162721065367?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D46150%26meid%3D37364e8098db461cafde03a71f17950a%26pid%3D100005%26rk%3D2%26rkt%3D6%26mehot%3Dpp%26sd%3D172936100608&_trksid=p2047675.c100005.m1851

What a total mis description and bordering on outright lies ???
Note the upside down mounted Albion gearbox

On French bikes, A friend who speaks fluent French picked up the remains of a 1929 Favor a while ago in France for
less then 200,
No engine, but the rest was almost complete,
The Staub gearbox and clutch (Burman pattern) were fairly well trashed but he was able to source another in France
and I rebuilt one from the two as the casing mounts differed
He had a JAP 250 engine that needed a home and it was an easy fit to the frame
Chambrie in France rebuilt the wheels supplied the tyres and made an exhaust and so on for very little 's compared to UK prices
It is almost finished now, at a fraction of the price of a pre 30 Uk built bike

So Colin,  keep going on the wee French 2 smoker  ;D

Hi,
To get true TDC make up a piston stop tool
I have made several and keep each one for different bike engines I set and lock them to the before TDC figure after setting up the protractor (degree disc)
This means all I have to do the next time to check the timing is screw in the tool
If you make one from an old sparkplug body and use 6mm rod, then its easy to set the desired figure as the thread pitch is 1mm.   (Of course this only works when the sparkplug is vertical with the cylinder

Hi,
With a flywheel magneto the "window" to get a good spark is quite narrow
The points need to just break when the magnets are evenly sat over the coil pole pieces
So in reality the magnets, piston and points position in relation to each other is fairly critical
The points opening position is more important than the fully open gap (in most cases) depending on the limitations of the points adjustment design
In my youth I struggled with various 2 stroke engines, even to resorting to converting to battery and coil in a bid to get good running ::)

HI,
2-3mm was just a base line figure to see if the bike runs
if 5mm is the book figure stick with that
If the timing was retarded, ie after TDC then unburned fuel continues to ignite in the exhaust system causing
the pipes to discolour or even glow red hot
Its best to go turn the engine back more than the book figure then rotate it in the running direction to the desired figure
Fresh paint can deceive as it cures giving off smoke and fumes giving the impression of lots of heat  :o

Hi
Wrongly timed ignition will cause overheating very rapidly
I would aim for points just opening 2-3mm before top dead centre
Have you checked this already??

Hi,
To add the ignition cutout, You need to add in an extra wire
Connect it to the junction where the coil/condenser are joined to the points, this is usually a little stud and nut
Run the wire to where ever you want to fit the cut out button or switch, the button body or other side of the switch
must be earthed/grounded to the frame/engine

Ok on the carb, just like all the old smokies, revs up when the handlebar is turned right and engine dies when turned left
 :o :o ::)

Hi,
Did the original carb have a tickover adjuster?
Usually they did not and the engine died if the throttle was shut off
If tickover is set on some old 2 strokes it can cause "surging"  as you shut the throttle when riding the bike
