high pitch whine

skyman · Apr 11, 2008

JUst got my FZ-6 a couple weeks ago and the bike is making a high pitch whine sound before and after starting. On my old bike I was told this was the CDI charging for the starter and it would go away after the bike was started. Does this whine exist on other peoples bikes after they start?

If this occurs when you turn the key on and the kill switch is set to run you may be hearing the fuel pump. This can also be heard after the bike is fired if you still have the stock exhaust.

That's what I was thinking, the fuel pump.

On a side note, let it cycle before you press the starter button, that way the system is ready to go before you begin cranking.

might just be the fuel pump, but mine seems to get quiet after the bike is started...

Drain the hippies out of the tank and that whining sound will go away.

After the first time that I rode mine (before it was mine) I stoped and it was still running and I thought what the hay....but it turns out that it was the fuel pump....

On another note, (a C# I think) I also hear the injectors as I am driving down the road...there are several new sounds on an EFI bike vs the carbs...

What do you hear in the injectors?

A soft clacking/ticking sound at idle. Sounds most like a partially collapsed hydraulic lifter, or pretty much the exact same noise my GM LG6 V6 injectors made.
