If you are going to use this disconnect to protect your C10 from hydrolock, you might need some of these. http://www.amazon.com/gp/product/B0051TPJKG/ref=s9_top_hd_bw_g263_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-2&pf_rd_r=0GJ2WQ493R5F7P0AWN9X&pf_rd_t=101&pf_rd_p=2125357502&pf_rd_i=13400621

I'd probably need those more if I have tubes leaking fuel onto the floor of the garage... or anywhere else I park

Here's a link to one. The price has gone up!
I have one on both bikes and use it for my bench supply tank.
They work quite well.

amazing to me how every few years we rehash the whole hydrolock protection deal, only to come back to the same conclusion.

and to throw some actual facts into the conversation, all engines in the zg / zx family that came after the original zg1000 had a clutched starter drive gear to mitigate the forces that would bend a rod. zrx's still hydrolock, they just don't damage the rods when it happens. HTh, Steve

Steve, what's the cc volume of the zg1000 combustion chamber?

salnap · « **Reply #84 on:** August 11, 2015, 04:04:46 PM »

Stopping the flow of fuel sounds like the logical solution

iirc about 17cc for the head. Somewhere I have all the math for the entire swept chamber, but not digging for it now. Steve

So if 1 ounce = about 30 cc's and the chamber at full compression is about 17 cc's then less than a shot of good bourbon will hydrolock the cylinder. Interesting.

very interesting. stopping the flow from the petcock saves that good bourbon

and I bet these things would run better on good bourbon.

At least with overflow tubes you know where the drip is, and it is not dripping over a hot engine.

LOL but if your petcock doesn't leak.....

We can just keep going and going....

There used to be a commercial on TV for one of the "tech" schools, " I don't have any money because I don't have a job. I don't have a job because I didn't go to school...." or something to that effect. The words went in a circle.

Most petcocks don't leak ... until they leak. What's your next line of defense against hydrolock?

salnap · « **Reply #91 on:** August 12, 2015, 11:56:59 AM »

Fuel filter. Then float needles.
From all the reading I've done, manual petcock like pingel seems to work fine. Some people have added in line shut offs.

Round and round we go

Disconnect the fuel line. ;-)

I think I may have said that.

Daytona_Mike · « **Reply #94 on:** August 13, 2015, 06:59:17 PM »

I had a manual fuel disconnect once. I hydro-locked the engine with it. I had to turn it on or the engine would not run. That was was before anyone thought of installing overflow tubes.

salnap · « **Reply #95 on:** August 13, 2015, 08:06:14 PM »

With all the hydrolocking that goes on I'm surprised there's any zg's left at all

There's more left than there would be because the smart owners have had overflow tubes installed.

salnap · « **Reply #97 on:** August 14, 2015, 04:42:36 AM »

why wouldn't the smart owner maintain ALL the contributing factors?

And many do; but apparently that may still not be enough....

Thus the backward step of putting back in what was left out for whatever reason an "overflow" tube....

Purely speculating here. I would bet there are quite a few petcocks that would leak if given the chance right now. However, the float needles are doing their job for now, so this goes unnoticed. That day when a grain of rust or sand meets it's new friend the float needle, there will be trouble. Kind of hard to prevent other than replace or rebuild every few years. Connie owners are notoriously frugal. Why fix something that isn't broke......
