Don't seem to have the time to look through these posts very often these days. Saw this and it surprised me as I've sold over 200 of these ignitions with only two come back. One buyer didn't like the idea of a wasted spark, the other had clearly attached the battery across the sensor input wires whi...

How tight are your nuts?
What would be the correct, or a sensible, torque setting for these 26TPI 3/8" acorn nuts retaining the oil feed union?
(Asking for a friend)

Ian, I've checked the C15 19T sprocket next to a late B25 item and yes the C15 sprockets have a deeper boss which is correct. OTJ writes; "In 1969 the main bearing in the gearbox was moved about 0.060" nearer to the clutch and the sprocket boss made correspondingly shorter to maintain the same chain...

Red line was 8200rpm but in tearaway years I always found power bands were at 4200-4500rpm and again at 8500-9000rpm hence short engine life.
With a worn out MX camshaft (deliberate for reduced lift) and Omega piston, keeping up with Yam and S*zuki two strokes was easy while it lasted.

Does anyone know what magnesium content there is in those old CCM covers?

Chris Pellett

you can always tell a pattern oil pump as your engine would now be seized solid!

Sad but true.

Chris Pellett

Minety,
Are you wanting the Made in England sticker or do you want to write something else in that style?
I may have some waterslide decals if you are after originality.
We use a similar vinyl version on the electric BSA's, PM me if you want some

I like the idea of a sprint on Brighton Pier, but it's actually on the lower promenade road; Madeira Drive and pretty sure it a 1/4 mile.
They used to run two at a time but H & S ruled in favour of the cast iron lampposts.

So last week Mahindra & Mahindra bought the BSA name in order to make motorcycles through their subsidiary Classic Legends. Maybe jumping the gun but here is the Mahindra Mojo, a 300cc single being compared to the Royal Enfield Himalayan. big_419502_1465567469.jpg All adds to the interest. Incidenta...

I was told the forming rollers for the rear were stolen (they are brass) so there would be no more rear ones made (in the UK).
Best bet is an undrilled T140 cut down at the front but they are from Taiwan, distorted and thin.

Lucas horns use this: s-l1000.jpg Fixing bolts to the frame bracket were latterly rubber mounted. If you must use the central bolt for fixing your horn, many Chinese bikes use two 1mm thickness strip brackets rather than one 2mm stainless strip like yours was. Two strips should dampen the vibration ...

Yes fits standard Lucas reflector

Agree with Nambo, 250 OIF mid range stutter; richness due "thin?" modern fuel, restrictive silencer or worn needle jet. Triumph twins invariably need the needle to be dropped with modern fuel. Dumping the lozenge silencer has been the done thing since 1971. And needle & jet wears fast with the pulsi...

Didn't mean to worry you John, just that Talon made a batch with the bolt holes too small. IMO anyone who can't handle a pillar drill shouldn't be changing the sprocket on a BSA (or working for Talon). Just might be prudent to check that a 5/16" bolt fits the holes before selling. Yours might be fin...

Chris Pellett

No big deal but check the bolt hole size before trying to fit

Chris Pellett

Found on the salt

Did you get it back?

Chris Pellett

Too busy to take pics until most had left. There were less bikes this year as it clashed with the Ace Café Brighton run. Never the less a good time was had by all.

You might find the hot starting is a hot coil issue; efficiency drops with heat (and age). Try a different coil.

I know what you mean Mark and I'm guilty on all counts.

Sly, you say you have a Mk1 concentric: The early Mk1 had a short jet holder, and different needle/needle jets to later carburettors. Your experience is consistent with these three components being mismatched. As did Tom I had that problem with my Victor which was caused by having the wrong needle i...

There are undersize ones in circulation, however 1.361" ones are available if you want them.

I've got a Sparx switch on my TR5T.
It has a headlamp flasher facility by pushing the horn button up which I have not connected as the horn is before the switch on the TR5T (switch to earth) unlike the BSA and Bonneville which have the switch first and horn to earth.
