Happy Easter to All!

While waiting for barrel and piston I'm re-wiring my electric installation.

I will stay with positive earth since I bough DVR2 regulator for that setup. For now will connect for 12V. I heard that shall work with original dynamo.

All wires done in head lamp and deep switch, horn button.

Now move to dynamo regulator and back light.

Shall be ready before other parts arrive.

I have ordered as well deeper inner clutch
 basket . Currently I have just 4 plates. This will host 5 as it should be.

Some other small bits as well will arrive soon from UK (Ester time was hard to get my parcel send -no room)

High spirit to have it all put back together and have it working properly this time.

Take Care

Who have you bought the clutch basket from?
If it is Draganfly I would get a friend to add a couple of extra welds between the supporting ring and the fingers.
When I removed mine to fit the NEB clutch the ring was loose - the spot welds had failed.  I've still got it and if I had to I could still use it, but drill and puddle weld each tongue to the band vs spot welds.
My B31 came with the shallower clutch and it seemed to work well within the power contraints.  Asking it to cope with a ZB34GS engine was tricky and a DBD34 600 was right out!
The deeper 5 plate clutch on the ZB is quite sweet and seems to be working well (so far!)

Just for information. The B31 originally had 3 clutch plates. The B32, B33, B34 and ZB Gold Star models had 4 plates. The CB, DB and DBD Gold Stars and A7 and A10 models all used 5 plates. For 1958 when the B31 and B33 changed to alternator with a 4 spring clutch they both used 5 plates.
I would think Dan that your bike would originally have used a 4 plate clutch but it certainly won't do any harm to fit a 5 plate one.

Hello Neil and Derek,
My basket comes from Fairdeals2017.
I guess it will be quality of the one from Dragonfly or worse.

With that knowledge that 4 plates is how it shall be I will think twice before doing any change.

Many thanks for your assistance it's of a great value to me.

Take care...

Happy Easter to you.
I bought a "Gold Star' rep centrestand from Fairdeals having missed a couple of genuine ones (same as s/a B31 and B33 for mid 50s).
The construction and material seem ok (it was for a 57 Competition frame) but the holes were odd size and in between the size of just the through bolt (very sloppy) and the sleeve that should fit between the stand tube and the bolt.
I had it bored to size and spent a couple of hours dressing the stops with files (how I know it is decent metal!) to ensure it fitted to clear the chain and did not sag below horizontal to ensure 'off road' ground clearance.

Thanks Neil,
Looks like I will need to check thoroughly this clutch inner basket before fitting.

Motrcycle on the picture looks splendid!
Congratulations!

Cheers

Was the fin broken by the "expert" machining shop?

Ian,
I'm not sure. Hard to prove . Either way it is his fault because of a insufficient packing.

Guess what? He doesn't feel responsible!

Fin is already welded with braz.
Luckily my friend was around to do it.

I have to lap cylinder head and put this back together.
Set valve clearance and timing.
Refill with new oil and ....start!

Fingers crossed 🤞

Hello,
Question.
Anyone has spare mounting bracket for a deeper switch (Lucas black bakelite) ?
The one type which goes mounted on clutch lever.

I have original switch in working order but mountings are to the handel bar.
Managed to buy clutch lever console from Netherlands. That would look nice especially left side brake console with horn is fitted and works nice.

Cheers

A photo of what you have and what you want would be helpful. I have some spare horn, clutch and switch brackets around here. My road bike has chrome push screwed directly to clutch lever mounting. Off roader has same chrome switch/push on its own man bracket (and is actually more convenient than the one on the clutch (as a dip anyway)
