1931 Sloper threads.

Hi. What would be the normal(expected) threads on a 1931 550 sloper. BSF, BSW, CEI ??

Advice appreciated.

all of the above, CEI 20TPI and BA. Typically BSW for threads in alloy, CEI 26 TPI as standard thread, BSF in cylinder, BA for electrical (switches on combination levers (5BA), magneto etc), CEI 20 TPI on footrest rods and bigger studs.
