90 Vulcan 750. Bike over heats yet gauge reads normal. Steam and coolant escape from cap. Replaced radiator cap and had system flushed professionally. Is it the thermostat or pump?
I am not sure as to your meaning that you had the system flushed "professionally" as I would expect any paid mechanic working on a coolant system would change the thermostat even if it was working just to be able to add to the billing process. Besides it is a simple procedure for a "professional" or anyone else with simple tools. Also, have your setup checked as you have at least two posting under this thread and yet are listed as only having one. The count doesn't matter much but maybe some of your postings are not making it onto the forum for membership responses. You can also try a post under the Newbie Check-In to let us know your riding/wrenching experience if you so desire. Most members do so. Good luck and try the boiling procedure that was described already.
and always remember, "Ride until you rot!"
