BSA Sunbeam
« on: September 30, 2006, 01:44:28 AM »
Hi, just bought a BSA scooter with no documents, i have read where the frame & engine numbers usually are on BSAs of this age but have so far been unable to find them.
Can anyone please point me to the exact position of them please?

The listed positions for the engine and frame numbers are:
Frame = somewhere on the main stand brace.

Engine = *should* be on the left side of the crankcase below the barrel joint.

Which model is it, the 250cc four stroke twin or the 175cc two stroke single?

You  maybe  interested  in  the  picture  of  the  BSA/ Sunbeam  assy  line  in  64  shop  at  Small  Heath.  It  shows  the  two  stroke  engines.   Both  types  where  built  together  (  twin  and  single )  I  am  secound  from  the  left  and  was  the  Inspector  in  charge.
