ER - Yes, I'm afraid I worded that wrong. I simply meant that it was possible to prime the GZ; I mis-spoke when I said that you do that by setting the switch to "reserve".

Danny - you're wrong about the 2 tubes for Run and Reserve- you got it backwards. Nothing is sucked out of the tank.
The GZ has a gravity-fed fuel system. The taller of the two tubes is for the Run position, the shorter one, closer to the bottom of the tank, is for Reserve. When you run of out fuel in the Run position, and you then switch to Reserve, you now can draw fuel out of the lower portion of the tank from the lower opening of the Reserve tube, another 0.8gal for another 50 miles or so (if you are lucky).
Both Run and Prime are vacuum operated, the valve is open to let fuel flow when the engine is running. Prime opens the valve so it can flow with gravity. Don't leave it on here for more than a minute or two or there will be fuel all over the floor from an overflowing carb.

Do you mean : Both Run and Reserve are vacuum operated. Prime is used before the engine is running and has vacuum.

Both run & prime need vacume to operate, prime does not need vacume to operate.your bike starts on fuel already in carb bowel,when running vacume opens valve I carb is empty use prime to fill as it don't need vacume.

Sorry,ment to say "run & res" On older bikes their was no vacume on petcocks. You had to shut gas off every time you shut bike off.

You were doin' great.....up to here!

Unless there is a fault in the carb.....bad float or needle valve......leaving it on PRIme will not cause a fuel spill. It is not a good thing to do because it defeats the safety shut-off AND the reserve function but it should not cause any immediate problem.

I think that is what he said, isn't it......well, maybe not exactly. :cool:

I think the terminology has Danny confused. It might be better to say: In the Run and Res. positions, there is a vacume shut-off that blocks the flow when the engine is not running.

The actual flow of the gas is not "vacume operated".

Easy-Rider,right on.you said it much better than I did.

My feeble old brain only had to work on that unconsciously for about 6 months before it all became clear!! :shocked: :crackup

Battery Tender, the only way to go. When I'm done riding I park the bike and plug in the battery tender[ Summer and Winter] The bikes have never failed to start due to battery problems. CMS
