Oh yes, the Fizzys that were around in my early days may have been able too burn my M33 (Nixsey) off at the lights but the sound we made was truly awesome and I consider we “won “on shear sound! Godzilla on steroids! RAHG

Are you sure that this is a B33? Doesn’t having the heavyweight gearbox, as do M20s and M21s, make this actually an M33? Certainly that looks like an M series frame too. There are internal differences between a B33 engine and an M33 engine. The connecting rods are a slightly different length and therefore the gudgeon pin hole is higher or lower on one or the other (I can’t now remember which way round is which). I found this out the hard way when I bought a new piston for the bike I bought which was advertised as a B33. Fortunately Les at Russell Motors had everything in stock. When I took it back and explained Les said, “Oh, you’ve got one of those!”. He even had original BSA oversized valve guides! The exhaust valves tend to run hot and can seize, necessitating replacing valves and guides often. Eventually the drilling in the cylinder head wears. BSA’s answer was to supply oversized valve guides which needed to valve guide drilling to be rebored to fit. Whether B33 or M33 they’re grand bikes. Have fun. If you ever see NXY 688, my 1st “big bike” on the road after my test, wish the current owner well from me and give my fond regards to “Nixsey” herself. We had a great time together with many cherished memories. RAHG

I have one for sal m 1942

AJS did an R10 500cc around this era...... if you re going to copy something lads at least have the courtesy to pick a new name !

It's misfiring on at least 1 cylinder. I can hear it.

My grandfather had one of these in the 30's. Amazing to be able to hear what it would have sounded like back then.

I have zundapp 61 but not move, because carburator problem

Can anyone please tell me what the thing on top of the petrol tank is? Not the petrol cap the thing that looks like a cut down German helmet. Cheers. Beautiful bike 👍

Awasome machine!

Nice collectors treasure does anyone knows how many 1936 flathead product before the knucklehead came out ?

What a beauty, What would the price be? Gorgeous..

hermosa tube una magnat debon 500 c.c modelo 1951

Не рекомендовал бы заводить на подножке. Сломается же.

Awesome; what a beauty👍

Piękny solidny motocykl . Motory z tamtego okresu to jest to co naprawdę lubię

Very cool!

No hand shift for the gears ?

I had one when I was younger, mine was a 1975 and a single

Piscia benzina il carburatore

Most of us who would view such a video know the many various four cylinder configurations. Is any current manufacturer offering such a configuration?

One way to gamble with an old classic motorcycle, take it out and drive it on the icy roads and snow. Motorcycles love moisture.

😍😍😍

Great bike !

Свечи для них уже не делают.

Beautiful

Cette moto est bien belle ! Hélas, c'est du deux temps avec son bruit de casserole ....

Nice, is it gear driven over head cam or chain?

Where do I get one cliff up in Charlestown had one of these bad Larry’s

I have started with restoration of beast like this . Can't wait to hear it roar after restoration .

loopt niet mooi hoor rookt veel te veel

I had one of these in Kiev. Rode it all over the city. Suicide shift was funny.

Now!!! That's what I call a motorcycle. Loads of character..and a FKG number plate to match.

It's a legend! Flat twin sound. Lots of weight, and load cap, and two wheel drive , alot to ask for a 750, and yet the bike was almost unstoppable

Sounds like retro construction machine 😂

Had one of these in the 70s, same colours, loved it to bits

That's one from 1973, the tank decoration proves it, but it's still a beautiful motorcycle.

I loving it..the uniquely design

my dad was blown off his 16H side valve Norton by the Vichy French mortar in ww2. Months in hospital. He loved that bike. Bloody frogs!

Do you know where we can find parts?

Again we invite these bikes

Tengo una modelo 1946 , con tarjeta de propiedad , cuanto ofrece $$$ , si le gusta coleccionarlas

Beautiful machine 😊
