Fuel pipe arrangemnt for 1950 longstroke B.S.A A7 "Star Twin" (twin carb) .

[Stephen Foster]

Wonder if a Member may have a picture or diagram detailing the arrangement of the above please ?
Trying to decide which sections would be copper tube / bends / dimensions , etc ?
The above for a 1950 longstroke twin carb "Star Twin" .

Very little detail information relating to the above ?


Best Wishes,

rare model ive only ever seen one and that was fitted with twin type 276 , I don't know if that was correct but did not notice any copper just black fuel line and the feeds to the undersides where linked

[wetdog]

this looks more the job BSA would have made I think

The pics in the reprint of a 1952 Star twin roadtest show what look like flexible tube, neatly down to each floatchamber.
Could be copper pipe though. No loops, whirls or anything, just down then across to a horizontal connection.
Probably cross-connected across to each other too, but that is not so visible.

What does the Parts Book show ?
It will detail each bit, and possibly even illustrate it...

Many thanks for the helpful comments .

"R" My "Star Twin" is the early Longstroke (twin carb) version ..these were discontinued in 1950 in favour of the short stroke single carb model .
Do You have a copy of that road test please ?

Even the parts list is vague & doesnt have details or part numbers for Mine .

Very Best Wishes ,
Steve ...
