Wotcha.

I've just been playing at motorbikes
The smokey one does lean a tad further than the non smokey one.

The yellow one is the smoking machine.

I dragged the thing down to the river, I must admit the temptation to lob
the bugger in was great, but I resisted and performed a little experiment.
With the bike almost vertical, it does smoke a little, but that could be
residual oil in the down pipe.
When on the side stand, smoke starts within less than a minute.

My next plan of attack is to remove the "sump plate" and see if I can modify
both it and the oil pump pick up.

Once again - watch this space

Believe me, this has crossed my mind, but short of pulling the engine apart,
there ain't an easy way to measure 'em.

Ah well - back to the garage with it.

One last thought on differences, do you use the same oil on both?

While I think of it, what did you do about 4-star fuel? Did you get the
head done and if so where did you go?

There's a Texaco garage by me that still sells leaded four star - hell of a
price though.
I don't bother with it, although my mate bungs a few quids worth in his
Starfire every now and again.
I'll get the head done when the valve seats start packing up - same on the
Guzzi, and that's been running for about five or six years now with no ill
effects ( famous last words - you just watch the exhaust valve seat drop out
now ).

Yep - same oil in just about everything I run.

I just happen to have a spare B33 bottom end - which is the same as the B31.
This spare bottom end was sat, upside down on the bench, and used to compare
clearances with the smokey engine. It seems the flywheels are the same
size. Bugger ! I removed the oil pump and made an extension so that it now
reaches to the bottom of the sump plate. The whole plot was put back
together - and the result was a resounding failure Thinking that the
oil may have somehow been getting down the valve guides when the bike was
leaned over, the next move was taking the oil feed from the head and routing
it directly back to the oil tank. No difference at all. I then removed the
sidestand and modified it so that the bike sits more upright. OK - this
hasn't stopped it smoking, but it take a bit longer before it starts now.
I've sourced a new oil pump - so that will be going in as soon as I get it.
My 'project B33' needs a new pump anyway, so it's a win-win situation.

Anyroad - it's getting too chilly to be playing at motorbikes, so I'm
grabbing my tea, then hitting the pub.

One other point, some British singles had baffles in the crankcase
throat to limit oil splash, don't know if A: that was the case with the
B31 and B: if so they have been removed. If the baffles were originally
fitted they should be on a BSA parts list for the model.

Talking of Starfire's, I seem to have "volunteered" to help a neighbour with
a bad knee fix a rear wheel puncture in one...neither of us having any
knowledge of SOBrit bikes, is there anything awkward I should look out for,
apart from none of my spanners fitting, when taking out the back wheel? It's
an early 70's one, I think.

I deliberately turned the engine speed up - it moves the oil quicker ( to no
avail ) and also lets the bike run for a few minutes longer before the
amount of oil fouls the plug and the whole plot splutters to a halt. It
smokes just as bad if you turn the tickover back to normal when on the
sidestand.

Cheers.

No serious problems. It should be a "quick detach" wheel. Just remove the
spindle and spacer, from the right hand side, and the wheel will pull out.
It's on splines - the sprocket and brake drum remain where they are. Same
back wheel ( more or less ) as early B31 - B33.

No such luxury on BSA pre-unit singles, I'm afraid.

Cheers.
