Racing an A10

[chamber66]

Large journal. Which ones are these?

[muskrat]

LJ cranks were std in A10's from '58, the big end journals are bigger (1.461" = SL, 1.687" = LJ) and the flywheel is bolted by 3 radially.

I actually have a tribsa I dumped a T140E engine in a bsa frame some 20 years ago and its ok, I have also put a Trident T150V engine in an A10 frame and that really was quick. I have to be honest tho I actually prefer riding my Super Rocket.

I would certainly say that an A7 or A10 is at no disadvantage to its subsidiary companies twin cam products on the racetrack.
I'm no trail rider but would suspect lightening the rolling chassis would be the main emphasis.
Depending on the nature of the tracks you race on the ultimate lightweight would be to race a rigid frame, no good if you run on bumpy circuits, but good enough for the Daytona BSA twins to clean up all opposition in '54.

Hi,

I have an interesting A10 Ally Barreled 780cc Twin carb Scrambler I may just part with if the right offer was made

Hi Musky,
Yes I saw that after posting my reply, probably will make a lot more than the modded head ??
For a racer the modded head would seem better value?? carbs and all

Julian,
Are you tired of the "Beast" already ??? or are you onto the next project ?


Regards
John

Sorry Julian, firstly because my wallet isn't big enough, and secondly I don't think you're serious

I don't want to take the p**s out of anyone (well actually I do ), but I have seen it in the flesh, and I can testify that it looks a mean little bastard.
When standing next to it something tells you not to come any closer cos' it'll eat you alive.....remember Christine? Well, me damn sure I vaguely heard Buddy Holly's "Not Fade Away" while looking at it....

I think that motor would be far more suitable for a sidecar outfit 

[JulianM]

Not totally serious 
But ................

Naa, not fed up with it but I Always find building them more fun than anything else!

Got two Laverda SFs on the go, one std and one rather modified, so not short of things to do

Julian

Was good to see you Morris,

I've read your thread Julian, which is what got me thinking about using a BSA twin. I also, now i'm older enjoy the building more.Not that I have your skills or facilities, which I have to say are very impressive .
Anyway, no doubt i'm going to burn in hell for this, but I picked up a B44 instead of a twin. Seemed the sensible option considering that this is my first British bike build. And i've never done a 4 stroke before. I mean there's just so many parts in that engine, whatever do they do 

[tombeau]

B44 probably a very sensible option. Big fan of BSA unit singles here.

[JulianM]

do agree!

A B44 shows a lot of promise!  especially if you look at the last CCM versions of what was basically once a B44.

good luck and ask if you need to know where all those bits go, I have no idea but am sure we can guess
