It would be nice know what sort of prices are quoted for both ways!
I think rims are about 100 each, And sets of spokes near to that??

I have stripped the engine.
I dont think a new bigend was really needed. There is JUST perceptable movement.
Now I have it stripped, I will fit a new alpha bearing.
I suppose the whole job was a waste of time and money, but I still want to get rid of the vibration.
I might try making a weight, 58% of the rod and piston (is this correct? ) Then drilling the flywheels as needed.

answering my own question!
I checked again.
Gripping the piston with both hands, push up and down, moving around and sideways.
Finally found a point where a very small amount of play was felt. Enough to hear a small click.
Im guessing that that is the answer?? ANY play is not acceptable??

Suggestions for a good supplier for replacement bearing please.

Singles / B44, Bigend, Piston. Bad vibration.

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??

I tried a C15 tank. it is too long to fit.
I would like to try a c25 tank, one of the larger volume ones,
 but they are hard to find, and expensive to try.

Have heard that one make of tank protection varnish for glass tanks, is no good.
Anyone recommend a good one?

Singles / Re: B44 gearbox
« on: 10 October, 2017, 06:12:57 »
I had a bantam which would jump out of top gear.
I found the pins or dogs (what do you call them) were slightly rounded on the ends.
I ground away the edges to make the corners less rounded. only took of about 1 mm on each.
That was successful.
My B44 threw loads of oil out by the sprocket, after I overfilled the primary case.
When I discovered where the level screw was, the leak was cured.
I'm at PE15 9PR.
How can I upload a picture of mine?

I have just done my second ride, about 40 miles. Outward, following Bantams at 30 MPH
Return, alone at up to 80 mph.
I found an oil leak was apparent. It was from the gearbox filler at the top. Strange?
The vibration was great. I lost the heat shield from the silencer, one headlamp bolt,
and my complete toolkit which was strapped on the rear mudguard.  About 50 pieces.
I managed to replace the lot today, from the boot sale.

Interesting point.
I want to keep the weight and cost down. For many jobs on a bike (Say engine bolts)
you need two spanners of the same size. Most new spanner sets come with the same size each end, so you would need to buy two sets.
I found Whitworth open end spanners with different sizes each end. Short ones for weight and space saving.
Photo shows chain lock, Black tape and plastic ties.Carrier tray is cut from a 5 litre plastic bottle. Red spray shows that they are whitworth.
I use yellow for metric and blue for AF types.
