Singles / B40 star best set up for wrong carburetor
« on: 12 November, 2017, 18:55:53 »
My 1965 B40 has a Amal 627 (428) concentric carb. 20 years ago Dave Smith of BSAOC said its from a Trident but is ok and recommended the set up as:

Main Jet: 140
Pilot jet: 20
Slide 3
Needle position 2
Needle jet .106

( I don't actually know how its set up)

I notice that the concentric that was fitted on some later B40's was a 626. So was Dave Smith right that my 627 as set up above should be fine. ?

I am presuming after 18 years of doing nothing in a garage I'll probably need to check/clean/service it. I did take it apart once but only checked if for crud & cleaned jets ( oh yes then had to emery the flange flat that my make over tightened).

I will see if I can the bike going, but would be useful to know if the 627 should be ok.

yes like that. I hadn't even realised it was integral with the air filter mounting plate (obviously come off on mine under previous owners). The one shown on the link seems to have gone. So will need to carry on looking.

Thanks both for comments.

Bess, thanks for your link. Not sure how I missed that - as I went to the site. I actually have the gauze, the rubber  ring that that goes round it, the circlip....... but not the housing (that from the diagram I've seen) it fits within.    If anyone has a spare one or happens to see one at an auto jumble let me know !

Will have to take the suggestions and for the time being rig up something in the tool box area so that it looks right.

Kind Regards

Singles / B40 Star air filter - what's the best option now

I have no air filter on my B40 star and on googling you don't seem to be able to get a copy of the original filter unit that goes inside the battery compartment/behind the air filter mounting plate.

The carb is an amal 627 and there's only about 15-20mm between it and the air filter mounting plate/hole into the battery compartment.

Anyone able to advise on my best options for an air filter ?

A good few years ago it was suggested to me that conversion to 12v was probably the way to go. But I think there are more options available in 6v & 12v   e.g Pazon sure fire

So still interested if anyone has experience with 6v electronic ignition systems ?  I shall wait and see if anyone is able to report on any.

(In the mean time I've other matters to attend to to see if I can get it started/running in any way).

Bulb is 6V. So I'm not going mad then.

So any comment on suitable/best electronic ignition kit available ?


Singles / 1965 B40 Star battery & ignition
« on: 03 November, 2017, 20:46:43 »

I have a 1965 B40 star that's been sitting in the garage for 18 years and I now want to get on the road.

The battery had died and was binned. On a quick search of web sites they seem to suggest it should be 12 v ? But I am absolutely sure it was a 6v  as when I had it running I had to get a 6V charger.  So were 1965 stars 6V? 

Also I notice that there are 6V electronic ignition kits.  Any advice on the best for a B40 star ?
