Singles / winkers warning light.
« on: 16 June, 2018, 08:07:09 »
I had trouble seeing the winkers warning light on my B44 headlamp. I have a windscreen fitted.
I would arrive at home, to find the winkers still on!
I fitted a very bright LED bulb to the top of the speedo (Black vinyl tape). This was connected to the same wires as the original bulb.
I found it would only light in one direction.
This was because the supply to the bulb was be opposite polarity for each side.
I solved it by fitting a full wave rectifier in the line to the LED. This was just four tiny diodes in a pattern, in the line.

Singles / petrol gauge for any bike
« on: 17 May, 2018, 10:59:32 »
Easily made gauge. I cant see how much fuel I have in tank below 1/2 full.
Picture 1.
A plastic T junction is fitted in the petrol pipe.
Picture 2.
A small strip of tinplate is trapped under the tank fitting, holsd the pipe, with air bleed.
Picture 3.
In action. tank about 1/2 full.

The Star and Garter / Spanners!
« on: 11 May, 2018, 06:56:11 »
I like to carry a full tool kit on the bike, in case of breakdowns.
I want to keep it as light as possible, so ..
I use an open ended set,  with different sizes each end. 1/4" x 5/16", 5/16" x 3/8", and so on.
This gives me two of each size, to work on a bolt and nut at the same time. A short set for space
and weight saving. I can always get extra leverage by linking two spanners, end to end.
Buying new? 
It seems that now, spanners are sold as ring one end, open ended the other. So, to work on a nut
and bolt, you need two sets of spanners!! Also (of course) Whitworth ones are rare.
My solution was to buy second hand from Ebay, not buying each one seperately, but a whole set
which is cheaper. I paid 9 for a set. Another cheap source is boot sales.
Buying new spanners, I find that the cheapest ones work perfectly well, no need to spend a fortune on them.
Don't forget lads -  A donkey, a wife, and a walnut tree. The harder you beat them, the better they be!.

Singles / Winkers problem, and solution.
« on: 19 April, 2018, 10:45:53 »
My B44 has the winkers warning lamp in the top of the headlamp. It is partly shielded by my windscreen.
I have not done much riding yet, and I need to concentrate on the road.
The lamp is hard to see. I find that when I arrive at home, the winkers are still on!
What to do?  - I have fitted a bright yellow LED lamp on the handlebars, pointed at my face.
Problem. It would only light in one direction. Why? The original bulb runs on reverse polarity for eachdirection.
Normal bulbs dont mind about polarity, but LEDs only work one way.
So, I made a bridge rectifier to fit in the supply wires. |This is just four tiny diodes, in the same pattern as
the rectifier fitted on the bike. These are just a small bulge in the wiring. Component costs - About 2 quid!

Singles / Pannier bags for 15 from Argos!
« on: 11 April, 2018, 10:31:29 »
These are of good quality and robust enough for our use. The joining strap has to be widened with a stout piece of cloth, sewn in.
I attached to the (B44) bike under the saddle, just behind the rear saddle bracket. Rear movement prevented by two black bootlaces
round the frame. Quick and easier to remove when not needed.
I will probably improve the rear end with a metal bar support later, mainly for appearance.
Three photos- if I can get them to upload!

Singles / Twin front brake
« on: 10 April, 2018, 09:21:18 »
I just remembered what I did to my B33 in the sixties.
The front brake drum appeared to be just pushed on to the wheel hub.
I bought two spare wheels from the breakers. (second hand parts were dirt cheap then)
I dismantled one wheel and removed the brake drum from its hub.
I removed the long spokes from one side of the second wheel, fitted the second brake drum
and finished by fitting the short spokes to the second side.
So, I had a twin brake wheel, without buying any other parts.
I think I may have fitted a balancing arm for the brake cable.
Thats all I remember. I never drove hard enough to reach a limit on the standard brake.
but it was the fun of creating something new which appealed.

The Star and Garter / Feartherbed frame.
« on: 05 January, 2018, 10:24:35 »

Just  casual thought-
When (in the day) I changed my B33 frame (with superocket engine) for the featherbed, I noticed a great difference .
The beeser was fine, but the norton felt as though it was 'on rails'.
Has anyone else experianced  this? Are modern bikes better?

Singles / B44 rectifier
« on: 31 December, 2017, 13:11:48 »
My bike died on the road, took me 1  1/2 hours to push it home.
No spark. Battery flat. Not charging.
Alternator giving 18 volts AC.
Rectifier giving 4 volts DC.
Do I need to replace the Finned rectifier?

I could not find a Zener diode on the bike, this must be in the rectifier??

Singles / B44 riders
« on: 21 December, 2017, 16:09:55 »
What top speed can you get?
I can get 85 MPH on the clock.
BUT, check against a sat nav shows its only 75 MPH.
Are they all like that?

Singles / B44/C15 tool box under seat.

I have made this.
Anyone interested?
I will give details and pictures.

Singles / new look B44
« on: 30 November, 2017, 08:32:46 »
I have changed the tiny tank for one twice the size, and lowered the rear mudguard.
I like the look, what do you think?

The Star and Garter / improvement for bike lift
« on: 25 November, 2017, 16:11:52 »
 At my age, I can no longer bend or kneel down to work on the bike, so I bought a full length bike lift.
The lift has a small vice at the front, to clamp the wheel so the bike cannot roll backwards off the lift.
However, there is nothing to stop the bike tipping sideways.
You have to steady the bike with one hand, and fit straps each side to hold it. Not very convenient.
I made this addition to the lift, quickly and cheaply.
Two lengths of timber are fitted next to the front wheel. bolted together at the top, and secured to the base with hinges and bolts.
The width at the top is right to fit the top of the tyre, and so hold the bike upright. A small wooden wedge under the front wheel
 is a quick way to stop the bike rolling back.

Singles / B44 head steady
« on: 10 November, 2017, 07:31:54 »
My B44 has steel bar head steady, going forward to the sheet supports on the steering head.
BUT, there is a downward facing bracket at the centre of the single top tube.
What is this for?

Singles / bsa clutch hub
« on: 20 October, 2017, 09:50:11 »
On many BSAs I have worked on, I have always found that the splined clutch centres,(see photo) and also the  engine sprockets will slide apart by hand, easily.
With my B44, they are both VERY tight.

The clutch took about 20 heavy hammer blows to get off.
The primary chain would not come off the engine sprocket, because of the closeness of the rear case casting.
The sprocket resisted all attempts to pull or hammer off.
I finally got the blowlamp on it, trying to avoid burning the chain. This was successful.

I have now polished the outside splines on the inner clutch centre, and used a dremel grinder to polish the splines
inside the outer part.
Now, the parts will slide together part way, then lock up.
It will take hammer blows to push fully in. I do not want to assemble like this.

How can this be???
Suggestions please.

Singles / B44, Bigend, Piston. Bad vibration.
« on: 13 October, 2017, 10:24:38 »
My B44 vibrates badly on a light throttle opening, opening to accelerate stops the vibration,
closing throttle to overrun stops it as well. This is most noticeable at high RPM.
So bad, bits are dropping off or breaking.

I thought it must be bigend play, or possibly smallend or mains.
I have stripped the top end this morning.
No play to be found at all. I  cant mend something if it aint broke!

I wonder about balance factor?  The piston is 71/798, 1/2 mm oversize. It looks quite normal.
I see bsa part numbers. 41/794 standard, 41/795 + 10 thou, 41/797  + 20 thou (1/2mm)

The engine is not loose in the frame. I cant think what it can be.
I will order a new rocker gasket, and rebuild when it comes.
Any suggestions? Do they ALL have this fault??
