Hi All,
Im new here. Great to see so much on this bike. Bit confused now after reading some info here.
I bought this bike from a malaysian guy in Penang years ago and brought it back to Australia. knowing it was an A10. After checking the pictures on the net this bike looks more like an A7. i counted 7 fins on the barrel. The frame stamped ZA7 and the engine stamped ZA10. working great when I got it here.
Went thru a vicious divorce and had to pull it apart and store it on the farm.
After 10 years I got it back together with problem which I talk about latter. If someone help me to identify this bike, will be much appreciated. Thanks in advance.
Regards
Vitto

G'day Vitto, welcome along- they all have frames that start with *A7 except for the much later ones, and I think I see yours is a plunger, so that'll be ZA7 S ***** ('S' for spring frame).
I have later type big fin barrels and they have 8 fins, so dunno about small fins, but maybe someone has either whacked A7 barrels on A10 cases, and I daresay a crank to suit- or they've done a long-stroke short -rod conversion (which I doubt), like one of the guys has done....TT/RR/??? (lost track)
Just Re-read yours, and ZA10 cases, that maybe another story that someone else knows more about
*beer* *beer*

G'day Vitto, *welcome*
Yep, I'd say she's had a cases swap. 7 fins = A7.
Eng # ZA10-101 to 4000 = 1950 Frame # ZA7S-6001
ZA10-4001 to 12000 = '51 ZA7S-14001
ZA10-12001 to ***** = '52 ZA7S-26001
Cheers

Thanks guys. I guess its now its an A7. Is it any advantage with the A10 caseing. How do i work out now the gearbox. Is it to an A10 specs, i stuck a rod down the spark plug hole and piston was at its lowest point and measured approx 4.5 inches if dat means anything. *sad2*
Bit disapointed turned our to be a mungrel.

There's no such thing as a mongrel A7/10. Just modified to personal taste. *smile*
The cases are the same just a different # stamp. The gearbox, primary and most cycle parts are the same as well.
Just ride and enjoy.
Cheers

Gday Vitto,
If you're not happy, I'll swap you a bottle of stone's green ginger wine (10 years old) and a Queensland state of origin maroon wig for it.
Better be quick, you don't get offers like this every day.
cheers

I'll up the anty, how about a crate of Fosters --- seeing as you guys love it so much *smile* *conf*
,in the meantime nice looking mongrel !! Vitto stop worrying about the numbers ,they can all be sorted just ride it ,if you don't have a smile plastered across your mug after half a mile which will need to be surgically removed I WILL be forced to send the fosters !!! enjoy , best wishes BobH

I don't think much Fosters is drunk in Australia these days, Bob.
They couldn't give it away in NSW when they took over the local brewery.

Yes it's sent OS to keep them away from our good stuff. I only know one fellow who drinks it, he's a race horse trainer. Guess who sponsors horse racing?
Cheers

I think I said it before, but the local Doctor used to drink it, said it doesn't give a hangover so I gave it a whirl........first and last time I took his advice ....*sick*
But to be fair when I was in Rome (Melbun) a few years ago,I did what one does in Rome- the pub round the corner from the F-factory (Clifton Hill) had $1.90 schooners(15oz.)- can't go too far wrong, and surprisingly not as bad, but only had one more for confirmation and let the sleeping dog lie, so it could keep all its' hair..... *conf*
Oh yeah Vic- if it has two wheels, makes a noise and has BSA(A10) on it, is worth using *smile*
Holler if yea need a hand..!
-
Bloody nice looking mungrel.... *good3* I'd be proud to own it... *beer* & welcome
-
Honestly guys I was only joking .... about the Fosters !! I wouldn't inflict on my worse enemys let alone mates plus I remember the outcry many months ago when I asked if anyone over there drank the stuff, wow I think I only just escaped being " moderated" for using offensive language.
Still one hell of a nice looking "A " Vitto,cheers BobH
-
You just made it Bob, by getting back on topic. *smile*
So Vito, tell us a bit about the bike.
Cheers

Thank guys you al very encourageing. The guess now " The song remains the same " no more A's of confuse. I will get it going though ' im over the hill and far away".
Regards
Vitto

Just be aware that over 60 years of meddling, anything is possible.
My A10 has 7 fins and is still a 650 A10!
but I use short rods...

thanks for 'fessin up RR, I thought it was you.....!

Vitto, just a thought but have you slackened the tappet adjusters off prior to refitting the r/box ( or has it will soon become known as " that piece of ally sent to seperate me from my sanity ") it can make it easire but if it is to slack the p/rod could get free ,I've heard that click a few times mostly its just slipped in but obviously the reverse can happen. You could get a pushrod comb but I think its a a waste of time as it moves the gaskets, this job gets easier with practice ,some times you can virtually sling it back together and it'll be great other times it's a real PITA ,just keep trying it will fit back ,best of luck, BobH
