Ground Wire to Cylinder Head Cover Important?

I know the ground wire is important, but my question really is can there be any damage by not having it connected for some time.

Here's the story:

I took my bike in for a warranty issue on the Cylinder Head Cover Gasket (all the 07 zx6r's has this problem). I got it back and everything seemed fine.

Last weekend I decided to check the valve clearances (12k service) and while I noticed that the ground wire was not bolted onto the Cylinder Head Cover :wow It was just hovering over where it was supposed to be bolted.

It's possible that it was left out by the shop that did the warranty work, or it could have rattled out. I'm not trying to blame anyone for it, but I do want to know if I should expect any long term effects from the ground cable being disconnected for about 10k miles.

Thanks in advance,
-Josh

It's the engine ground.. you have a couple.. engine to chassis.. chassis to battery.. Not a big deal if everything is clean.. but I'd put it back on. Just make sure it's not connected to a bolt with a rubber grommet.

That's what I figured, but the cover seems very isolated from the rest of the engine. The gasket is entirely rubber, and all interfacing parts are rubber as well.

Actually, I guess it makes sense to ground it since it is so isolated. I definitely reconnected it though.

Thanks :thumbup

The more grounds the better! Electrolysis occurs when electrical current routes itself through the engine's coolant in search of electrical ground.

A poorly grounded engine and starter motor can zap enough current through the cooling system to blast apart a heater or radiator in a matter of weeks or even days, depending on how often the vehicle is started. A partially grounded electric cooling fan, on the other hand, may only shoot a small percentage of its supply voltage through a cooling system, and the effect may take months to reveal itself.:wow

If it was there from the factory. There is a damn good reason for it being there.
