My CB900C was very difficult to start after winter storage because the fuel
in the carbs would evaporate. Refilling the carbs is difficult to do simply
by cranking the engine over, because the amount of vacuum produced is not
quite enough to open the vacuum operated fuel shutoff valve fully. Unfortunately
this bike doesn't have a PRIME position on the fuel tap (even if it did, it
wouldn't help, because the vacuum fuel shutoff is separate from and downstream
from the tap itself). What I used to do was attach a Mityvac vacuum pump to
the vacuum line going to the fuel shutoff valve, or you can even apply vacuum
by mouth, depending on how much you suck
Even if you have sufficient fuel in the carb bowls, you may have plugged up
the idle circuits with fuel residue after the fuel evaporated. In that case,
it may take a good long time (or never) for the SeaFoam to work. The only
sure cure is to R&R the carbs.
