Question of quick-connect fittings

[muggy X]

OK - I'm new here (hello everybody)

I've read about using the quick-connect fittings for the fuel lines, which I'm interested in.  I (think) I've also read about the bike being on prime and eventually overflowing the carbs ...

My question is - with respect to fuel flow: what's the difference between free-flowing quick connects and the stock petcock being on prime overflowing your carbs?

Sincerely,

quick connects let you disconnect the line without gas splillage and turning of the fuel on the tank.

The Petcock position has to do with vacuum operation (res, on) or non-vacuum (prime).

Quick disconnects are nice if you remove the tank a lot and have to get to the carbs etc. Changing the petcock changes where/how the fuel is coming from the gas tank. If its vacuum operated it will only pull gas when the engine is running and gas is stopped at the petcock, if its not vacuum operated gas will be free flowing only to be stopped by the needles inside the carbs.

Welcome to the board!

My question is - with respect to fuel flow: what's the difference between free-flowing quick connects and the stock petcock being on prime overflowing your carbs?

Just adding the quick connects into the current fuel supply system won't affect fuel flow at all; ON and RES and PRI will all work the same as before.

But let's say that you REMOVE or BYPASS the stock petcock altogether, and run a fuel line directly to the carbs.  That would be just like having your petcock on PRI all the time, with the gravity-fed fuel always available to your carbs.  (But they shouldn't overflow unless you've got a real problem in your carbs: dirt, worn-out seals, etc.  Some board members have run this way for many, many miles with no problems.)

If you're concerned about the possibility of "carb overflow" you could add in a simple ON/OFF petcock and switch it to OFF when the bike is parked.

Thanks for the responses guys...

Yeah Jason, trying to get this thing running right, I am having to remove the tank a lot!

Yeah - that's kinda what I had in mind - bypassing the stock petcock and the free-flow situation it would present.  So if it ain't gonna overflow - barring any problems, then I guess I'll give it a shot.
