Hello all. I'm about to pcs and ship my bike. One of the requirements is absolutely no fuel in the bike. Curious what the best way to completely drain the tank is? Any suggestions would be appreciated.
Ride it until you think the majority of fuel is gone. Then remove the tank and pour the rest into a bucket. You will need to let the tank vent open for a day or two. If you don't want to remove the tank, you can siphon the fuel out, but there will likely be more residual that way.
I have seen a kind of cool way to drain gas by having two hoses one you place in the tank and the other you put in the tank and blow air into the tank. This causes the gas to start draining. As long as you keep the hose at the lowest point of the tank it will get it out. This YouTube video shows how to do it:
I've only needed them for one-time uses. I have bought a new one each time so they don't take up valuable garage space, so can't really comment on prolonged use. They are all plastic, with no rubber seals, so I imagine the gas would not be too harmful. I do know these will NOT work on anything thicker(oils) than water/gas.
You can also get a manual pump siphon at any of the big box hardware stores for a few bucks.
They work pretty well for a while (though there is likely to still be some residual gas that will need to vent out for a few days with any siphon method) but since they're plastic they tend to develop leaks after a few years. But for your purpose I think this is another alternative.
Well I got all my gas siphoned out. Tried the 2 hose method but the way our tanks are designed it would just vent everytime you blew in the hose even with the top completely covered. So that didn't work. Ended up finding a cheap little siphon pump for $5 and it worked great. Only issue I had was the permanent bend in the hose from packaging. Had to mess around with it but in the end I got it to work. Thanks for the advise guys. Saved me from pulling the take.
