I am posting this for one of my local vmax riders here in MD:
He has a 1990 vmax that in stop-and-go traffic when the engine temperature rises, it begins running very badly and has poor off-the-line throttle response (lots of sputtering and spitting to get moving). It is not over-heating, and the cooling fan is working. But when this happens, the float (fuel) level in one or more of the carburetors drops significantly, which I believe is causing the running problems. Once I get moving again, the problem goes away. I don't know what could be causing the low fuel levels, but I think that the heat is causing the fuel to boil in the bowls. I have tried everything I can think of except replacing the fuel pump.
Any suggestions to relay to him would greatly be appreciated.
Thanks,
Mike
