Singles / B31 head onto B33 Barrel
« Last post by sidewaysid on 20 February, 2018, 17:11:24 »

I'm sure Andy Ingham can put me straight. I have a B33 barrel and piston but my B31 head won't quite fit, would it be fine to turn a little out of the diameter (it's only about 2 mm) is this common practice ?

Hi Thumper. I have almost the identical 1971-72 diagram, it does not show the black switch that is on the top of the headlight shell. It would appear that mine was factory fitted ? Can't find it in the Lucas manuals either, a right puzzler ? Just looked on Dragonfly site, they list the switch in the headlight 19-1095 as a Kill Switch and in the price list they call it a lighting switch.

It sounds as the two-position ignition switch and separate lighting switch relate to those of a 1973 A65 as shown?

Singles / 1950 B31

Hi All
More help for my 1950 B31 please.
In one end of the big end crankpin is a grub screw, what does it do and does it need to come out and be cleaned behind.
On the drive side crank shaft is a ball race, spring ring, distance collar, roller race and oil flinger BSA list a engine shaft shim 66-661. Were does this go there wasn't one on there when I stripped it.
All the best

I am about to buy a new ignition switch for my 1971. I was lead to believe that all OIF's had a four position switch. I too have a switch on the headlight shell. Does anyone have a definitive answer on these 1971 and 1971 OIF's, sorry to hijack thread.
Which BSA do you ride? / new to the forum and classics

I'm a bit new to bikes, however my Dad was into them in his day.  Unfortunately he passed away a short while ago and I've been reminded his M20 is still sitting in my workshop.  Technically its my brothers now, but he has no mechanical ability so it looks like its resurrection will fall to me.

I know very little about the bike other than my dad got it before i was born in early 70's;  all its history and reg  are missing although i remember my dad getting it on the road back in the early 90's for a couple of years before an accident stopped him riding.

The bike has been off the road since early 90's however it ended up sitting out in all weathers for a few years before i moved it to my place about 7yrs ago.  It is siezed solid right now so looks like i've got my work cut up for me!

I restore classic cars (mainily minis) myself and do have a degree of mechanical ability, but bikes are a new think to me. Plenty of reading and research ahead

Thanks Arther
Actually the light has been very high since rebuild.
I can't see how to adjust but will take your advice and obtain another bulb.
In that case, as said by Julian, you may have to adjust the alignment ring on the headlight. When you do this, you need to adjust the alignment of the dipped beam to make sure it satisfies the MOT alignment template for your bike. The main beam should then be ok unless there is a problem with the bulb.

They should be flat sealing washers. There would have to be a bevel in the mating surfaces to allow an O-ring to be used.

If you have thestandard nacelle there are 2 screws on the black rim , shown on the parts list photo below, which fit in elongated hole which allow some adjustment of the beam.
