Petcock kit install
« on: May 27, 2013, 11:12:00 am »
I acquired a petcock rebuild kit and want to install it as a proactive measure. My 2005 Connie has never exhibited a problem related to the petcock but after almost 9 years it seems prudent to install new components. I know Steve's overflow tubes are the only real solution to potential hydrolock but the petcock kit seems a straight forward install. I have searched the topic and found a number of posts regarding poor results. Any tips on installing the kit? Should I even bother? Should I just order a new petcock from Murph?
Thanks guys, always a pleasure communicating.

More than a few have installed the old fashioned manual type petcock kit. Something to look at if you are thinking of other options. Not sure of Murph sells them or not.

Murph has some recommendations on his site:  http://www.murphskits.com/catalog/product_info.php?cPath=1_94&products_id=121

Murph does also sell a kit to convert the stock petcock to a manual one:  http://www.murphskits.com/catalog/product_info.php?cPath=1_94&products_id=483

I rebuilt my OEM petcock several years ago using a K&L repair kit.  It leaked immediately because the parts in the K&L kit were bogus.  I found that the diameter of the center poppet and O-ring were too small to seal the central passage in the petcock.  I got fed up and installed a Pingel manual unit and am happy happy happy.  It has been reported by some here on the forum that the genuine Kawasaki kits are better than the aftermarket ones.  Be sure to inspect all the parts in the kit you got and if they are not identical in all respects you may have trouble.  Obviously you'll want to do a leak check before you install the unit or put fuel in the tank.

I installed Murph's manual petcock conversion kit this weekend.  Easy-peasy and no leaks.  Murph advertises Permatex aircraft-grade sealant and I went for that as well:  outstanding stuff!

I hope you folks with manual petcocks have over flow tubes.  If not you are  much more likely to hydro-lock the engine than with the auto petcock
If you still have fuel in the tank, you are not lost yet

I just installed a Briggs & Stratton lawnmower shutoff valve. Always works and cost $3.50.

I'll continue to beg to argue that as false..... All one needs to do is turn on/off the tap; my job as a ship engineer requires that I follow precise procedures over and over again without fail or forgetting.

With that being said I believe that overflow tubes are worth far more than their cost as the human machine is subject to failure too.

As to rebuilding petcocks with factory parts yes... Rebuilding petcocks with K&L no way!

I am with Tony on this one.  I NEVER forget to turn it off.  Just a matter of learning to do it.  I mean, do you forget to put your foot down when you stop?  Do you forget to put it in neutral before you let out the clutch at a stop?  Do you forget to get gas when the tank gets low? 

I am confident that the manual shutoff is OFF when it is turned off.

The examples given above don't really help.  In each there is a very direct and immediate reaction for failing to do X or Y.  This is not the case with the fuel valve.  I suspect that each of you who "never" forgets to turn off their fuel valve have in fact done just that.  How can you even say for sure you didn't?  Maybe you just as easily forgot to turn it on.  What would have ever drawn it to your attention?  I still think that even subject to failure, the vacuum pet cock is more reliable than people, at the very least MOST people.  I certainly know myself well enough to know that (it) would be more reliable than me.  Maybe I speak for myself but that's just fine with me

jworth...you said "...I would be more reliable than me."  OK.  I guess.

Okay, I agree with your immediate consequences point.  So how about this one:  Do you ever forget to take out the ignition key when you leave the bike?  That is comparable to the petcock question. 

Speak for yourself...I NEVER forget that, and I am trained to associate the key with the petcock.  Other folks do what they do, but I was speaking for myself alone right from the beginning. 

The same kind of debris that could cause the vacuum shutoff to leak could plug the overflow tubes.  Then hydrolock!  IT HAPPENED TO MY BIKE TWO MONTHS AGO!!   The (new) manual shutoff really shuts it off!  Oh, and I have the tubes too.  But they are less than 100% reliable, by actual experience.

Well, you managed to hit on three reasons why I won't do the manual conversion.   ;D

Do you ever forget to take out the ignition key when you leave the bike?
Make that four reasons.   :rotflmao:

Remembering to turn off the fuel is not the problem. Even IF you always remember turn off the fuel your worse off than an automatic petcock and here are the reasons.
 Automatic petcocks shut off the fuel flow the very instant the engine is no longer creating vacuum. That goes for starting the engine as well.
Humans  are  no where near as fast as automatics and certainly not every single time you stop the engine to say: add fuel to  the tank or when you open the petcock just before starting the engine. All these short instances of start-ups and shut downs   which occur many times during a single  ride has your  manual petcock  flowing  full wide open even if it is for a few seconds and  that is all it takes at full wide open and full pressure (plus a leaky float valve) to cause a hydro lock.That does not happen with an auto petcock even on  a failed auto petcock. The very worst failures on an automatic petcock is a slow dribble at low pressure.

So again if you have an automatic petcock make sure it is maintained. If you have a manual petcock and even IF you always turn it off and ON as fast as you can EVERY single stop AND  turning the fuel flow on before  the starting   of your  engine your  increasing your risk 10 fold over automatics.  It normally takes overnight with a dribbling Auto pet-cock to cause hydro-lock  but  it only take just a couple of seconds with a wide open full flowing manual pet cock.
JMHO.  Thanks
 

If you still have fuel in the tank, you are not lost yet
