NOTE: BSA SERVICE BULLETIN DATED AUG 20, 1971 HAD A WARNING ABOUT THEIR RECOMMENDED CARB SETTINGS:
"The B50T/SS models are fitted with 220 main jets, and the needle position in the first notch. Tests indicate these settings are too lean and can cause piston seizure. RECOMMENDED ACTION: Install 240 main jet and raise needle to the middle position on all B50T/SS models."
ADDITIONALLY: "In high altitudes, the suggested 240 Main jet may be too large. In such cases -- raise the needle jet to the middle notch, and use the 220 main jet."
