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??

Singles / B44 oil leak
« on: 26 September, 2017, 07:29:57 »
I had ridden my new B44 only a few times, maybe 50 miles.
Apart from a big end clanking, the gearbox sounded noisy.
I used a syringe to get oil in the tiny filler hole, up to the mark on the dipstick.
I wondered if the primary was also running dry.
I could not be sure which was the oil level screw. Rupert ratio did not seem to cover my model.
When I started up, oil was gushing out from the sprocket area.
I did a trip to a jazz concert, four miles away. The clutch was slipping badly, 50 mph max.
On the return it was almost back to normal.
I assumed that one of the seals was leaking, or perhaps missing.
I tried to order two new seals ,but could not find the part numbers for these.
I have difficulty bending down, but finally found the there were two small screws, together under the middle of the primary case.
These must be the level and drain plugs. I drained the excess oil and I think the problem is solved.
Then I read in the ratio book that the chain oiler was a problem, and should be removed. I will try that today.

Singles / insurance on B44
« on: 23 September, 2017, 07:08:19 »
I insured with BIKESURE.
They have insisted that I use a SOLD SECURE security device at all times.
I bought one of the cheaper options 20
It is a very large chain and padlock.
It weighs 9 lbs.
How am I supposed to carry this on a Scrambles style bike with no room for a carrier?

Singles / centre stand spring
« on: 15 September, 2017, 09:25:27 »
Fitting is very difficult. hear's how I did it.
Spring on the frame.
Bent pianowire hook on bottom of spring.
Both ends of chain on to wire.
A long crowbar, stuck in ground, pull the top end. 2 to 1 leverage.
Bike was laid over to give access.

Singles / B44 VS steering
« on: 14 September, 2017, 08:19:50 »
I have just bought one to replace my C15 SS.
First ride for 1/2 mile, up to 75 mph.
I found that the steering felt very light and I was afraid that a speed wobble might result.
Tyre's are 3.25 x 18 front and rear, normal pattern.
I wondered if a ribbed front would help, or could the fork trail be too little.

Singles / B44 centre stand
« on: 07 September, 2017, 07:52:52 »
I am looking to buy a B44, 441.
Do they have a centre stand, or can one be fitted?
I start my c15 on its centre stand. It is much more difficult off the stand.
I doubt I could start the bigger engine that way.

Singles / Advice wanted on choice of BSA model.
« on: 03 September, 2017, 08:29:24 »
I am 78 3/4 years old (The three quarters are important)
I rode bikes  in my youth, finally a Norton featherbed with super-rocket engine, built from parts.
I recently bought an A10, but it was too heavy for me to manhandle.
I bought a Bantam D175. Its top speed was 65 mph. Too slow for modern traffic.
I restored a C15 SS 80 mph machine, but it was no faster than the bantam. (but sounded much nicer)
I tried a Yamaha virago 250, which easily did 80 mph and was good, except for very heavy  low speed steering, and silly riding position.
I want that sort of performance from a lightweight British classic.
I am thinking B44.
What advice?
Anyone got one for sale?
I am in east anglia. There are several for sale, mostly 4 hours drive away.

Singles / Whats good about motorcycling?
« on: 24 August, 2017, 07:53:33 »
Whats good about motor cycling?
Forgetting that its cold (even in summer), its noisy (I like the noise).
Its dangerous. I like to pit my skill and roadcraft in riding.
Its uncomfortable. (I only do short rides now).
Whats good.
Getting it to start first kick every time.
Bends are fun. I feel I am using my body in a natural way
.similar to skiing or surf riding but much easier to do, at any time.
Leaning over. not just turning a steering wheel.
Overtaking any slow traffic stuck behind a Lorry.
Straight to the front at traffic lights.
But mainly nostalgia! When I was a Lad------.

Singles / C15 bore size.
« on: 22 August, 2017, 08:50:15 »
A quick question.
C15 bore is 67 mm. Mine is plus 40 thou. = 68 mm?
Is this correct?
I have found for sale, a 10:1 piston with a 70.85 mm OD.
