Which BSA do you ride? / 1971 OIF Thunderbolt
« on: 27 January, 2021, 20:06:58 »
Got a little Thunderbolt about 9 months ago...already had an older restoration done on it...have got bills from PO for around 18 grand!!!
Engine has lots of SRM bits in and on it.
It was apparently ordered for the Aussie police, but that came to nowt as BSA were boogered...It was eventually registered in 1973 at Queens Park Motors in Salford. Got a little Starfire in trials trim with a b40 lump in it too....

The Star and Garter / wheel building

Hi folks,
Have any of you used North East Wheelbuilders near Chester le Street?
I need to get two wheels respoked and they seem to be the nearest to me.
Don't know anything about them though.
Cheers, Pete.

Singles / Imperial bearing size
« on: 31 July, 2020, 17:14:19 »
Me again folks...groan...
As mentioned previously my B40 engine has been fitted with some metric bits and bobs, including the gearbox layshaft bearing in the primary side casing. The layshaft fits in but it's not a close tolerance, ie hammer time, so the bearing doesn't turn properly. It's shiny on the inside so the layshaft is turning inside it. This plus a lack of felt washer might be a cause of my leak?
Anyway, does anyone know the correct size of bearing to install  please? I'm still not au fait with old money yet sorry!! :-[

Singles / B40 nut size
« on: 26 July, 2020, 21:00:02 »
Hi folks,
Finally got around to stripping down my rather incontinent early B40 engine. Found a few problems, one being the use of metric bearings when it's been rebuilt in the past!! Doesn't help to keep things leakfree....
Anyway, Just about to split the casings and wondered if anyone knows the sizes of the casing nuts? There are two sizes and I don't want to start grinding down sockets to fit in the recesses until I know the size to use......anyone help please? Many thanks in anticipation...Pete.... :D

Singles / drippy sump B40
« on: 31 May, 2020, 11:17:19 »
Hi Folks,
I seem to have oil continually sitting in the rectangular shaped sump which, obviously, leads to seepage and drips on the floor.
I've checked RR's book and the Haynes and it would appear that the tube on the left should have a non return valve fitted? Ball bearing?
When running, oil is pouring into the tank so no apparent problems there.
There's nothing in the tube, even gentle poking with thin wire reveals no resistance up the tube.
Is there something missing or am I missing something?? :-\

If pic looks familiar, I nicked it from an old post, thank you.

Singles / Don't want to break it!!
« on: 23 May, 2020, 17:22:57 »
Hi folks,
hopefully getting to grips with this mongrel but need a bit of light shone on a wee problem. :-[
Put the timing cover back on carefully, ensuring that pushrod mechanism was in correctly and kicker return spring was hooked on. Plug out...kicker installed...turned engine over three times and returned fine...on fourth kick (by hand) the kicker would not move. Don't want to force anything in case it breaks! Any clues? Please?

Singles / Is it a B40 lump?
« on: 15 May, 2020, 20:13:58 »
Hi Folks,
Just easing myself back into BSA ownership as the big Jap multis are just too quick for me now!
Anyway, I have a pre OIF B25 frame with, what I believe to be, a 350 side points B40 engine. ( Serial Number 1973)
I've taken off the timing side cover as there was gearbox oil slowly seeping from the kickstart shaft when on the centre stand. When I removed the lowest fixing bolt it seemed to act as a drain from the gearbox...Is this right?
I've looked at the Haynes and Rupert Ratio's book and can find no mention of this drain bolt anywhere?
Also the only drain hole I can see on the inner case is about 1/8th diameter and located behind the kickstart quadrant.
Did BSA just drill these willy nilly or was there a set pattern?
There was some gear oil in the casing too so I'm guessing that it was maybe overfilled? Defo not engine oil.

Sorry for all the questions but I just want to make sure I've got the engine I think I've got???  :o

Many thanks in advance,
