new idea on fuel petcock
so i finally got my scoot from the bottoms area here in KC to our new house in the waldo area, fun drive for 1 in the morning, but to many hills for my taste. However i think my petcock went out on my way here, got home put the scoot in the garage and started to reek of gas.
haven't had the time to pull it apart to find out whats going on, but it got me thinking. what if instead of having a vacuum operated petcock that seems to love to fail, we just wire up a relay off the run switch to a fuel solendoid? this would negate the issue i would run into of not turning off a manual valve when i get off the scoot. because lets face it, i am stupid.
so then as long as your key is turned to run, and the run switch is set to run as well the fuel will flow. but if you take the key out, or turn the switch to stop, it will cut all fuel. i am not sure if this would put any strain on the electrical system however.
but here is the problem, anybody know where to get one that does not cost 100 bucks. i am thinking more in the range of 20-30.
tell me what you think, or if you can figure out any better way to do it.

Re: new idea on fuel petcock
I don't think you're going to find one anywhere near the price range of a replacement petcock, hence why Honda did it that way originally.

Re: new idea on fuel petcock
That solenoid is made for non explosives,water,air,diesel(yes you can get diesel to"explode",but under very high pressure/temp.).Like in an engine.This thing probably can cause a spark,thus potentially causing a great deal of excitement.Best look some more.....Always looking for more excitement,Carp.

Re: new idea on fuel petcock
A new petcock is $20, even that non-gas solenoid is $30.
You really can't go wrong with just a new petcock.

Re: new idea on fuel petcock
yeah, i guess the heat is getting to me. i thought this up while re insulating our new houses attic. this would probably be something that really would be better under the KISS method. one less part to go bad. or atleast if it does you can still run the scoot...
ok, still, that being said, any one find any nice fuel shut off valves? i may just go the hardware store route, but i would prefer a 1/4 or 1/2 turn valve.

Re: new idea on fuel petcock
It takes 200 psi to ignite diesel. Yes, I just imagine that would produce 1000 deg. F. Gotta get the heat from somewhere in a cold engine, and compression is the key.eliteguy50 wrote:at about 1000 deg. Fcarp wrote:(yes you can get diesel to"explode",but under very high pressure/temp.)
Flashpoint of gasoline is very low. It's more dangerous than gunpowder. Believe me, I deal with gunpowder and never had an explosion. I have had a few calamities with gasoline.

Don't be thinking of a shutoff for gas lines ,don't think they are made for gasoline( remember gasolineworks geat as a solvent).Carp

Re: new idea on fuel petcock
There are several petcocks on the Parts For Scooter web site.There is a link to it in the wanted/for sale forum under great places to buy(think that's it,4th one down).Look in accessories,big scooter gas tanks or atv/dirt bikes, $9-$17.They even have vacuum actuated ones(some have adapters available to make them more versatile).You might try Scooter Therapy(link same forum), or a lawnmower/landscaping shop.

Re: new idea on fuel petcock
Hey,what scooter are you talking about?Spree,Early/late SA50?My beater '95 SA50 has almost 7,000mi with the original petcock,that's not too unreliable.The guy here on the Spree/Elite forum that is making the Spree big bore and gear kits has an ebay store(alluneed) that has petcocks at a good price(heck find a post of his ,pm him asking how much w/shipping).Carp

Re: new idea on fuel petcock
sounds like yours is stuck open and the carb has float/needle/seat issues. You could try finding a manual motorcycle petcock.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.
Re: new idea on fuel petcock
My wife's elite E had same issue. I rebuilt a carb I bought off eBay, left the old petcock on it. I bought a petcock from alluneed, but didn't install it. With Carburetor repaired, I don't need it now... or should I say... not "for" now. Maybe later.Kenny_McCormic wrote:sounds like yours is stuck open and the carb has float/needle/seat issues.

Re: new idea on fuel petcock
If they were trying to KISS, then why didn't they just make it manual? Probably didn't fit in with the side plastics?

Idiot proof, same reason the choke is automatic.
