Fuel pump noise fzs600. No front wheel speedo drive ,lack off grease

[gerkin]

Anyone has to swap their fuel pump mine gets really loud at 30mph ,at least I presume its the pump
Its either a high pitched wine like wind through a visor or rattle like the relays fked

Odd. I would have thought the pump noise wouldn't be related to road speed.
Could be the speedo drive in the front wheel? Makes a terrible whine if not enough grease

As a test you could temporarily unplug the connector to the pump and listen if the noise goes away when it's unplugged. If the noise goes away the problem is most likely the pump, if it's still there you know the problem isn't the pump. The bike should still run ok with the pump temporarily disconnected
