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

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 / new look B44

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??

Singles / b44 speedo

My 150 mph, rubber  clad speedo has a trip function, but no reset control!
How do I reset it?

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?
