Singles / Its alive !!
« on: 06 April, 2018, 18:00:27 »
Still restoring a 1955 plunger B31 which was a virtual basket case this time last year. Just got the oil system connected up and thought " I  wonder if it will go ?"...so filled the carb with a funnel (no tank or seat yet) and it fired up second kick...absolutely amazing as it hasn't run since about 1974 !

The Star and Garter / MoT and Registration class changes
« on: 05 April, 2018, 09:00:21 »
Hi guys
I would appreciate little help on the procedure for changing the registration class of my bike(s) from "Motor Bicycle" to "Historic Motor Bicycle";

As I understand it the 'transaction' has to be done at the Post Office- it can't be done on line; there doesn't appear to be a "V" form for the request so presumably I will need to attach a note.

So.....


1971 Bantam B175; on a SORN ;Restoration complete and as the reg it is pre 1978 it requires an MoT before submitting the V5 with a classification change request.

1955 B31; on a SORN; Restoration nearly there; as the reg is pre 1960 it doesnt need an MoT certificate (although it would obviously be sensible to get it checked)  - submit V5 and V112 (Mot Exemption Form)  with the classification change request.

1954 C11G- in need of a complete re-build; details as for the B31

Is this correct ?

cheers      :-\

The Star and Garter / Buyers Beware !
« on: 11 March, 2018, 11:08:39 »
A warning to anyone contemplating an ebay purchase from Classicmotornos;

I had a bid accepted on a 1948 Girder M21- as per the attached picture; When the courier arrived to pick the bike up he was confronted by picture 2- a dismantled pile of bits.
The main picture on ebay depicts a complete bike and its only when delving a little deeper into the description that it suggests different.
The courier said that there are quite a number of bikes dismantled under tarpaulins in this guys garden and most are out there on ebay so beware if you're in the market for a restoration project. Had the price been say 500 I wouldnt have worried unduly when when your talking 2500 its a different kettle of fish.

I've cancelled the order and am trying to get my money back- its not an insignificant sum !! so fingers crossed !

Singles / B31 clutch & primary drive
« on: 13 February, 2018, 17:38:23 »
A little advise please-

I'm trying to rebuild the primary drive and clutch on my B31 (M m series gearbox + 6 spring clutch)

Inner chain case and sliding plate fitted -
-felt and cork washer behind the splined sleeve-
-2 row bearing and rear plate onto the sleeve

all as per service sheet and manual- but when I fit the clutch centre and tighten the mainshaft nut it tightens down but leaves the chain wheel loose and- for want a a better word "wobbly"- Further tightening of the nut results in the clutch centre becomes fixed and will not rotate

I cant see what I'm doing wrong- as the order of assembly is as per the worksheet and I cant really see how else it can fit together- what am I missing ?

any thoughts ?

Singles / Oil feed/return pipes
« on: 07 January, 2018, 09:39:00 »
Hi guys
I would like to fit some shiny new armoured oil pipes to my B31 plunger; but all those offered for sale have a 90degree elbow union on one end; the fittings both into the crankcase and from the oil tank are obviously straight...  am I missing something ?

Singles / B31 front hub rebuild
« on: 22 December, 2017, 17:43:39 »
Hi Guys

I'm rebuilding the front hub on my 1955 B31 plunger after having the wheel rebuilt and after putting it together as per the service sheet it just doent "feel right"
I would have thought that the outer shell of near-side bearing should be flush with the lip inside the hub and therefore recessed into the hub by about 1/4"; but when put together the edge of the bearing is just about flush with the edge of the hub- see pic. The bearing is correctly positioned on the spindle- ie flush with the retaining lip and the bearing on the other side appears to be in the correct place.  Its so long ago that I stripped it down I cant remember what the original looked like;
There are 2 washers- a thick one with a cut-out (why I dont know) and a shim- I'm assuming the thick one goes on the inside of the off-side bearing and the shim on the ouside of the near-side bearing- the diagram on the service sheet isnt very clear, but in any case the dust cover wont fit

Anybody throw any light on this ?

Singles / gear selector problem
« on: 06 November, 2017, 12:30:09 »
B31; 1955; M series type gearbox

Help !... this is doing my crust in !!!  I've assembled the gear selector unit as per the service sheet but once the springs are on they pull the pawls away from the ratchet plate. When I put the unit into the box I have to lever the top pawl carrier past the stops on the gearbox
I cant see there is another way of putting it together...believe me I've tried !... so what am I missing ????

Singles / B31 gearbox query
« on: 30 October, 2017, 17:45:01 »
In the process of putting back together my B31 (plunger) gearbox- according to the bible it is imperative that the dot on the selector quadrant is lined up with the dot on the casing...slight problem...got a dot on the quadrant but there is nothing on the casing.... any ideas ?

Singles / B31 Magneto oil seal
« on: 19 October, 2017, 14:51:32 »
Hi guys

Partway through a B31 rebuild and come to refit the magneto; I've put a new oilseal in the housing - my gut instinct says spring/open side  to the inside- ie towards the pinion or into the timing chest...  but when I've peeled the old seal off the pinion its fitted the other way round- ie spring towards the magneto.

Which is correct ?

Singles / B31 Small end bush
« on: 28 September, 2017, 16:52:32 »
Hi
Rebuilding a 1954 B31 and the small end bush is u/s- virtually in two pieces..so clearly a replacement is required. (Bike hasnt run since 1974 )
Obtained a new one but it is far roo large both internal and external. Now I've just had an interesting chat with a nice man at Hawkshaws who have stocks of "old" "new" stock but he thinks these were supplied "unfinished" by BSA and need to be machined (reamed) prior to fitting....anybody come across this situation ?

cheers

« on: 23 July, 2017, 15:47:28 »
Hi
I cant get the cush dive nut off (B31 1955  Plunger) ...its been really butchered by a previous owner but I cant get it to move; There doesn't appear to be a tab washer behind it- between the nut and the spring- I've tried stiltsons and a big hammer but cant shift it.......any tips gratefully received !!
