Singles / Fuse ratings
« on: 19 March, 2018, 21:59:57 »
I notice that in my Haynes workshop manual, at the start of chapter 6, Electrical Equipment, the fuse loading is given as "35 amps - all models except the earlier Star series." I'm not sure whether my 1965 B40F is an "earlier Star series" - I guess so. The Haynes book doesn't say what the fuse for them should be. But I was wondering: why 35 amps for some models?  Seems a lot to me. I was thinking of maybe about 15 amps for mine. Obviously I'd need to add up all my wattages before finally working out the rating. But 35 amps seems a lot. Is it because the horn is included perhaps?   Phil (novice)

Singles / Electrical things

Pilot light bulb had blown so I got a new one. Didn't work. Armed with my new multimeter and almost no knowledge, I tested between the live battery terminal and the pilot light connection: about 6v, so I guess okay. Tested continuity of bulb on my resistance (ohms) setting: about 0, so presumably okay. Tested continuity from headlamp hole (where spring clip of pilot light clips in) and battery earth point: about 0, so I guess okay. Across the battery terminals I get a reading of about 6v, so I guess okay. If I press the rear brake pedal, the brake light comes on. So why doesn't the bulb work? Am I missing something blindingly obvious?  Phil (novice)

PS If I am asking too many questions on this forum, please could someone let me know - I won't be offended!

The Star and Garter / Nuts and bolts

Can anyone recommend a supplier of very small quantities of nuts, bolts, screws, etc, including imperial sizes?  Thanks.

Singles / Petrol tank removal
« on: 13 March, 2018, 16:59:35 »
Yes I know, I have to ask just about every step of the way. I need to remove the tank in order to examine the wiring on my 1965 B40F.  I have taken the two nyloc nuts and the metal strap off, and the tank appears to be loose both at the back and at the front, but something seems to be holding it in the middle. Peering up underneath I see foam, wires, and a plastic tie, but don't know if that tie is holding it, and can't think how it could be.  Don't want to tug too hard on the tank if something is holding it. Could it be?  Phil (novice.)

Singles / Twistgrip
« on: 12 March, 2018, 16:18:37 »
Could someone enlighten me please: there are two screws with locknuts - what are they for?  Thanks.  Phil (novice)

Singles / Throttle cable
« on: 12 March, 2018, 16:12:19 »
I've got problems with my throttle cable and twistgrip, and am embarrassed to say I don't know anything about them or how to adjust them. Should the item on the photo screw into the hole in the twistgrip housing?

The Star and Garter / Can't attach photos
« on: 12 March, 2018, 14:17:35 »
Does anybody know why I can't post a message with a photo - it always bounces back telling me the file is too large?  How can I do it?  Thanks in advance.  Phil.

Singles / Front lights not working
« on: 11 March, 2018, 14:01:45 »
I'm going to have to do a bit of investigating of this, but would be interested in, and thankful for, any thoughts in the meantime. On my 1965 B40F (6 volts) the front lights aren't working. I turned them on this morning (without the engine running) and got a glimmer of light for just a second and then nothing. The battery can't be completely dead because a) a test light comes on when connected across the battery terminals, and b) the bike starts, so there must be current getting to the coil. When the bike is running the ammeter indicates the battery is charging a bit, esp when the engine is revved.  Any thoughts? Could it be that there is enough in the battery for the coil but not enough for the lights? Thanks in advance for any suggestions. Phil (novice.)

Singles / Multimeter

Can anyone recommend a cheap, reliable multimeter?  Phil (novice)

Singles / Air filter hose
« on: 01 March, 2018, 15:48:49 »
The hose I've taken off my 1965 B40F, which joins the air filter (housed in the side panel) with the carb (Amal Concentric), is a bit worse for wear and I thought I might replace it. Its dimensions are roughly:  outside dia 2"; inside dia 1 and 5/8"; length 2" (although I might cut it a bit shorter so that the filter unit isn't jammed up so hard against the frame inside the side panel.)
Any ideas where I might get one please? Someone suggested getting some silicone hose, as used for car radiators etc, if I could find something that size.
Thanks in advance.

PS Turned out nice again!

Singles / 1. Air filter, and 2. carburettor
« on: 27 February, 2018, 13:45:24 »
I took the air filter off my 1965 B40F this morning. Inside the outer metal mesh are two slightly finer metal meshes, and sandwiched between them is a piece of some kind of cloth. Out of interest, is that a normal set-up? 

Also, I'm going to take my carburettor (Amal Concentric 626) off to see if I can solve why my bike refuses to run without a bit of choke and yet has a black sooty spark plug. I know nothing about carbs other than what I've read, but I have some info from Amal (thanks again, Julian S). My stupid question is: when I start to take it off, should I first remove the cables from the handlebar levers, or leave them attached even when I take the top cover off the carb? Should I just leave them attached both at the lever end and at the carb end, even when I take the slides out of the carb?

Thanks in advance,
Phil (novice)

Singles / No spark
« on: 26 February, 2018, 15:48:34 »
Looking to investigate the fact that my "new" 1965 B40F won't run without a bit of choke and yet has a black sooty spark plug, I thought I'd start by checking the timing, before moving on to air filter and carb. So, I've fitted a new set of points plus new backing plate and new condenser, and set the timing. I tried to start it this afternoon, and found I now have no spark at the plug. I've tried another plug. The points are opening and closing, and there is no spark at the points.  Gaps at points and plug are okay. Also front light won't work, although brake light and horn do. I have a loose wire hanging near the carb but don't know what it is or what it might connect to (maybe an accessory fitted in the past?) Any suggestions please as to why there's no spark at the plug?  Phil (novice)

PS I am realising, in the early days of my new retirement hobby of classic bike maintenance, that nothing is simple!

Singles / Tappet cover sealing washer/"O" ring
« on: 20 February, 2018, 13:38:11 »
When I took off the (hex-head) tappet covers on my 1965 B40F, they had flat fibre washers and goo.  I decided to replace them with new ones, but on enquiring was told they should be "O" rings, so that's what I bought. On fitting them this morning, I found that anything more than extremely gentle spanner pressure causes the ring to squash out of the side of the cover. There is no groove for the "O" ring. I am a bit concerned that the covers are not on any where near tight enough to be secure, but also that if I tighten the cover any more then the ring will distort out of the side of the cover. Should they be "O" rings or flat fibre sealing washers?  Phil (novice.)

Singles / B40 side points 4CA base plate
« on: 15 February, 2018, 18:13:35 »
Anybody had difficulty fitting the 4CA points base plate because of the condenser wire connection nut catching on the wall? If so, how did you get the base plate to fit in the hole?  Elongate the screw clearance hole at the other end of the condenser holder? I'm not sure that will make enough difference.  Phil (novice)

Singles / Grease gun
« on: 09 February, 2018, 18:26:23 »
I'm looking to get a grease gun for my 1965 BSA B40 - maybe an old secondhand one from ebay? But how do I know what kind of gun will fit the grease nipples on my bike?  Phil (novice)
