Traveller fuel cock

Hey there, this is my first entry.

Last april, at last I bought me a Skorpion Traveller.
Somewere on the web I had read that the fuel cock could be a bit tricky to reach. And on my Traveller it was almost impossible to turn unless I used both hands.
I had to buy a new fule cock. But still it was a bit hard to turn, particularily when it was time to turn it to the reserve.
I had to make som kind of lever.
A "hook" glued with Araldite and reinforced with wire.

One finger is enough.

I never turn mine off.....no issues.

I need a the cup and the filter for my spare petcock.

Any other MC uses this style of petcock ?

Did I understand correctly that the engine filled up with gasoline because the petcock was left on for an extended period ....?

i have a bad habit of not turning mine off

they should be turned off each time you stop

if carb leaks and intake valve is open a real mess can develope
in the crankcase

suzuki made a 3 cylinder 2 smoker in the 70,s SUZUKI GT380 and 550 72-77
that would fill up the crankcase
of one cylinder and when it started on the other 2 it would strip the piston right off the rod

it would do it if gas not shut off and also would dump the autolube oil tank
into crank case if left set in the winter

these were 2 of the best suzuki's i ever had but shut off the oil and gas
or you would be replacing a piston soon

"bad Habit?"

dunno.

when we're talking about old(fashioned) Amals or Dellortos or Bings just after the war, that is one thing and I know from experience not to trust them.
But modern carbs of good design and materials don't need to be shut off ever if you ask me.
I don't shut mine off - I don't even have a petcock installed. I habitually remove them, replacing them with a quick-release hose connector. In the case of the Skorpion, the petcock is notoriously too small, another reason to do away with it. The quickrelease makes removing the tank easier in any event and on any bike. On the Skorpion in particular, where the petcock catches on the wiring harness and has to be carefully forced thru every time. And the quick-release can of course do double duty as a shut-off where it it is necessary; you can't be better shut off than entirely disconnected.

NB: the SZR has no conventional petcock nor any vacuum or electric one.
It does have a sort of faucet, but that can only be reached once the tank has been lifted; it is only to be able to remove the tank.

this is the kind between two hoses:

and then there are those in which the valve part is threaded and screwed into the the tank. Both Ducati and Aprilia have these as standard equipment. I get mine from the Aprilia dealer and he also has the proper tap to thread the hole.

Bill

can you supply a brand name and part number for the disconnect you show
would like to have some but live many miles from any MC shop that would stock this stuff
a local ATV shop will order stuff for me if i know brand name and part numbers
ar dave

bmw shop 100 mile round trip closest they have ever been

most are 350 plus its 380 to look at ducati and triumph
the royal enfield from india is 650miles sold by the fellow that sold me the MZ
the MZ shop where i got the rt125 is 650 mile round trip

the reason i got to working on my own bikes was no dealer to serve me
so a mail order bike is the same as buying one from a dealer
you just miss out on the 500+mile round trip

Yet Another Warning- always shut off the petcock. If your float level isn't set properly, you run the risk of fuel dumping out through the float bowl drain hose. I'm not sure how the drain is set up on the Baggies, but I've walked up to my bike sitting in a pool of its own gas before.

Kind of brought up a good point though, I wonder if I have pluged or pinched vent hose for the fuel to go into the motor. Confused

Bill - do you have a picture and Aprilia/Duc part number for the fuel valve part as a replacement for the stock MuZ petcock.

Thanks

BTW - link to that great quick connect valve.
