Just thinking....how did he manage to balance it all up if the big ends didn't fit.... *conf2*
I assume he must have weighed the rods and bearings and took the weight up in the calculation?
Someone who knows may confirm or deny this or explain how a crank is balanced? I would like to know too.
I don’t see how you could run a crank on a balancing machine with the rods on. They would swing al over the place and the reading would be incorrect.

Here you go (static balance only)

you made a good decision there, I have been playing with two old abused amals on and off for years. then a mikuni sold as jetted for my bike that was ok once I got the bike started but was a pain hot or cold. the new carb has got the bike back to a first kicker no matter what. yesterday the girlfriend noticed the bark and crack of the exhaust note. BUT the best bit was when we got in the house and she said " betsy was so well behaved I didn't have to move my leg for you to start her again at junctions and traffic lights she just kept going BA DUM BA DUM BA DUM, music to any BSA owners ears *grins*

41 years ago i found out when stripping the engine that the the crank had snapped , after collecting another engine i took that one to pieces and started on the present day café racer bike build, i found a couple of pics from 1980 when i started putting things together again. of course i haven't yet started using the modern phone so these were taken on the foggy phone

Update. Bottom end together and looking good. Pistons on. Barrels on. Head on and doing up the bolts. Got to number 9 and promptly stripped the thread. So....Head off barrels off and back to Mr. Fleabay to purchase a helicoil kit and drill press. Do remind me why I didn't buy an Xbox..  someone?

Tony,

Just for grins, maybe try sending a PM to our member Dutch, who is also in Brisbane. He may be able to help, either with the coils and press or, at least, with some good advice.

Dutch, if you're reading this and I am volunteering you against your will, I owe you a beer or four. (Tony, I'm sure it's going to be OK.)

Is that a fact, (or fake news) ?

Dutch's profile says his location is "BrisVegas," which I take to mean Brisbane.

G'day Tony.
Finding a shop to do a 3/8" BSF helicoil might be hard.The job itself is easy enough.
Haven't heard of duTch since January. I know he goes to BJ's Bikes and Bits, they may be able to help.
Cheers

Yeah, I think I confused word that he lives with him actually posting here, which he hasn't since 12/19. 

(BTW, I also read his last posts just to be sure it wasn't me that set him off *eek*. Maybe he'll return by saying. "I definitely was you, you dumb sot!")

 Depends on which hole it is. There may be sufficient depth of casting below to drill down and tap the original thread, and a custom bolt. UNF or a more modern ******ing Metric fine would be an easier choice, again with a custom stud or an ex car cylinder head bolt to suit. Sacriledge I know, but it would be your li'l o'l secret.

 Good to know the worst is over (el cranko etc)

 Cheers.

 Swarfy.

It's head bolt no.9. So at the back of the head on the timing side.  Managed to pick up a BSF 3/8 x 20 helicoil kit that comes with the correct drill bit and whatnot. To be fair it was a good excuse to get a decent drill press. Now.....what else can I destroy to justify a lathe  *smile*

 Per Swarfy's sacrilege point, on that very hole I have used a 7/16 UNF stud (originally from a Jaguar cyl head set), turned down to let the head pass without fouling, and threaded 3/8 BSF at the top for a suitable deep nut. It's done loadsamiles and no problem . Also, under the rocker cover, so hidden as well. Not a rolled thread obviously, but if a decent 3/8 high tensile die-cut thread can't take and hold 33-odd ft lbs we might as well all go and kill ourselves  . . . !
I committed the sacrilege because I felt I'd get a better result than with a thread insert, and also because I  prefer studs and nuts to bolts and setscrews on principle (even into cast iron). If there was the space for it all to go together with the engine in the frame I'd replace the lot with similar frankly.
Just another little nudge towards that lathe SuperF!

I have heli-coiled many barrels successfully.
