Wanted: Pics of Jeff Smiths 1964 BSA

I think we all agree that the B40 should be included in pre65 Dave, providing it has the B40 frame and NOT the later b44 frame that the last B40's came out with. The problem with including the B44 in pre65 is that no one will want to ride the B40 up against the more powerful B44. Not when we're racing for sheep stations ...
As Firko said, the B44 is a very competitive bike in pre70 with a good rider controlling it. Even more so when it's had the big bore treatment.
I have to admit to having an interest in any attempt to move the B50 back to pre70 but I can't see that happening unless the date was changed to pre72, which, in my opinion, is a much more aligned date than pre75.
But, as the saying goes...If it ain't broken, don't fix it

I do agree pre 72 era, as it should be, b50, b44, came match it together, the straw can be broken and fixed to the right era, I think it deserves a shot. at national level, B40 into pre 65.

      -- Sorry i dont agree with the above on frames ,as stated back in reply #51  ive had my C15E(enduro) frame number's checked on database's before and it came up as 1964 , Then on reply #52  JC reckons those same later "competition" style frames were introduced in 1963 ! Iam thinking those same looking Non- Oil -In  early B44  frames were carried over from 63' up C15/B40s , and we all know B44 soon changed over to Oil- In frames  and B40 kept them right thru from 63' .

I think this may have been posted before but it's a good read

Great read! Plans for a Ti Bultaco frame look like being shelved. Just concentrate on the Carbon fibre guards and tank instead. J PS Is Frank still going?

I'm assuming you're referring to Frank Melling Jerry. As far as I know he's still kicking.....

        Hmmm  interesting ! a distributor motor/cases with side-point  inner and outer timing covers - no major upgrade there 

[sprint76]

Looks like there also mods to the cylinder and cylinder head. Larger than std exhaust would also indicate that there has been a increase in valve sizes.

  Looks like an optical illusion ! dont know that bike but army B40s use a std 1-3/8" header and  std  valves  ,the earlier SS90 uses" big valve" and certain other unit single heads right back to 1960' -all in rupert ratio book
