'78 CB750K carbs vs CB750F carbs (PD42A vs PD42B)
« on: February 26, 2017, 08:08:49 AM »
Are the carb bodies on these interchangable? I need a #2 carb body to complete my CB750K carb set (PD42B) but can only seem to find #2 bodies from the CB750F model (PD42A).  Does anyone know if I could switch out just the carb bodies?

Don't know for sure, but willing to bet that you can. AFAIK the only differences are the pilot and main jet sizes, which you can swop over.

Try a PM to harisuluv for a definitive answer.
