Welcome, and don't be afraid of asking silly questions, I often do - there really is a wealth of knowledge in the club.
Best tip I can give is collect a decent set of imperial spanners - open ended and ring and a decent metric socket set has also come in very handy.
Good luck
Chris

As ever, thanks for the info, looks like mine is indeed a tight wire advance, could be a pain in the a%*e if the cable snaps!

Steve, it's going well, engine complete as are the oil lines, the mag is on the bench being 'looked at'. Forks are ready to go on and the plan is to have a rolling chassis next month

Cheers

Singles / B31 Manual Advance/retard
« on: 11 October, 2017, 15:48:11 »
Hi All,
I wonder if anyone can help with this question.
I have a Lucas MO1 Magneto with the advance/retard cable housing on the left hand side (Looking from the drive end) Right hand side (When looking at the points)

I think that this is a tight wire advance set up and the timing should be set with the cable slack (Retarded) and the lever operated to advance the timing for normal riding.
Please see attached pic, not my mag, but lifted from a flea bay page.

I'd appreciate it if someone can confirm it is a tight wire advance.

Cheers
Chris

Hope you sort it soon, don't give up.
My advice is Spark, Timing, Fuel. Check and more important double check.
If it's sparking and the timing is OK, is there fuel?
Is the plug damp?
Have you blown the jets out?
Is there decent compression?

Good luck

Singles / B31 Engine sprocket shims
« on: 17 September, 2017, 21:32:36 »
Hi all,
I need some advice (again) & I wonder if anyone out there can help.

I need to align the engine sprocket to the clutch chain wheel and I am looking for some suitable shims. I can see shim kits for an A7 and I suspect they would also fit the B31, searches for specific B31 aligning shims seems to draw a blank.

Does anyone know if the A7 shims would fit, or where I could obtain specific B31 shims.

I have a 4 lobe spring shock absorber and I think I need to move the sprocket out about 30 tho (ish)

Thanks in advance,
Chris

Hi all,
I bought a compressor yesterday from lidl for 79 along with an air- gun and ratchet attachment

had a play with it in the workshop last night, and the air gun with various nozles is fantastic at blowing away all the bits of crud stuck in the hard to get to nooks and crannies, beats a tooth brush hands down.

The ratchet set is 1/2" drive and I think the max torque is 61 nm

Its 79, it only has a 25L tank and has a max pressure of 10 bar, but in my humble opinion for the average 'Shed bike builder' its a serious bit of kit.

Thought I'd share this as I suspect they will fly off the shelves.

Singles / Re: B33 Exhaust valve guide
« on: 12 September, 2017, 22:05:59 »
Hi Bess,
I am having problems with the exhaust valve on my B31 and shortly I want to get the head reamed and if necessary fit an over size guide
So the dimensions you have given are of great interest, but can I ask you to double check?
The outside diameter of a standard exhaust valve is 5/8" (15.875mm)?
But what is the diameter of the hole to accommodate the guide including tolerances?
Thanks in advance,
Chris

Hi all,
I am thinking of fitting a concentric to my B31 to replace the 276 which is now cream crackered, I was thinking about the Amal 626.
Any thoughts?

Cheers

Singles / Re: B31 loose valve guide
« on: 03 September, 2017, 22:09:41 »
Sorry to drag on but I am trying to get my head round this, as I understand things, the notional diameter of the valve guide is 5/16th? Taking tolerances' into account - in a perfect situation should the hole in the cylinder head be 5/16th and the guide itself be slightly bigger to accommodate the interference fit?

If the valve hole has worn what should the diameter of the hole be to accept +2 or + 4 though dependant on wear?

Thanks in advance,
Chris

Thanks for the replies, I'll get the hole reamed, checked and a new guide made.
If a job's worth doing it's worth doing right.
Cheers

Singles / B31 loose valve guide
« on: 31 August, 2017, 22:34:26 »
Hi all,
Head and barrel now stripped, the plan was a thorough clean and paint, but I have come across a problem, the exhaust valve guide was loose with about 1/8" play up & down.
I made a drift and knocked the guide out, after the initial play the guide was tight in the head.
When the valve was put in the guide it is "sticky" at the point where the valve would have been in its seat.
New valve and guide obviously required, but I am unsure what to do to make sure the problem does not reoccur.
New guide with Loctite and hope for the best? Can you buy oversize guides (I remember doing that to a Triumph years ago) or will the guide hole need reaming and a guide made to suit?
I'm a bit stuck on this one, and as ever any advice is really welcome.
Cheers
Chris

Singles / Re: B31 stand

I use a generic bolt on side stand mounted just behind the rear brake fulcrum (Rigid frame), works well with no problems.
