I ordered a kit, will let you guys know how it goes.

Question...
okay,..ranty question... Huh

If the purpose of the vacuum petcock is to prevent a stuck float from being able flood the bike while parked... isn't the flood going to instead occur after you get underway?...and wouldn't you rather breakdown in any parking lot, rather than on the road?...
And,.. if the vacuum diaphragm prevents such flooding, but when it fails it, automatically causes it,... is that a gain?...
and on top of that,... the flow is much stronger, and more direct, down the vacuum line, than through the float needle so it makes a worse one...

Now,... in an accident, if the bike ends up on it's left side and the float needle sticks, it will shut off the flow, as long as the engine dies when the bike goes down,... but gas will still leak out of the tank vent and the full float bowl ...
(if the bike falls on the right side, no gas will flow from the petcock anyway)...

So, basically as far as I can see,... it's a non-solution to an unlikely problem, with the side effect of adding cost and complexity, and giving a better way to cause the same problem it is designed to prevent in the case of failure... which it has a known propensity to do...

Huh?... Huh

...

PS,... and on top of all that, it's fugly, and makes the tank hard to get off... Grin

If the purpose of the vacuum petcock is to prevent a stuck float from being able flood the bike while parked and unattended ... isn't the flood going to instead occur after you get underway? crankcase flooding, not possible. flooding intake, noticeable. bike pissin' on shoes, priceless ...and wouldn't you rather breakdown in any parking lot, rather than on the road? No ...
And,.. if the vacuum diaphragm prevents such flooding, but when it fails it, automatically causes it,... is that a gain?... Is it negative that everytime you get off your bike you forget to turn off the petcock causing the float valve to fail someday?
and on top of that,... the flow is much stronger, and more direct, down the vacuum line, than through the float needle so it makes a worse one... and on top of that your bike is so ill maintained that the valve clatter and due to low oil level the bearings sieze?

Now,... in an accident, if the bike ends up on it's left side and the float needle sticks, it will shut off the flow, as long as the engine dies when the bike goes down, I never crash with a full tank of gas, bad form you know ... but gas will still leak out of the tank vent and the full float bowl ... only until the tank is half emptied
(if the bike falls on the right side, no gas will flow from the petcock anyway)...

So, basically as far as I can see,... it's a non-solution to an unlikely problem, with the side effect of adding cost and complexity, and giving a better way to cause the same problem it is designed to prevent in the case of failure... which it has a known propensity to do...
But look at all the maylasion rubber tree planters you're keeping employed. It's recommended that you replace the rubber under your hood every 7 years, does anybody do that? And yet a rubber diaphragm goes bad and you get all bent out of shape. I get an '02 with all original rubber. That petcock works great on the leaky '96.

HF sells a vacuum assisted brake bleeder for about $20 Hook that puppy to the vac port of the petcock and pump up 5 lbs of vacuum. If it holds steady, no leaky.

I expect that once it cleans the system the emission would be lower. Just wonder during use.....

One thing I will note, every petcock I've openned up has a coating of silt on the inside. How it gets in there I can't fathom. How seafoam will clean it out, I can't comprehend.

Comes with a gasket and 2 o-rings 1 o-ring fits the lever, the other is too big for anything. I'll have it in the bike tomorrow.
