Here’s a quick video on how to siphon a motorcycle tank. It’s Episode 3 of my Kawasaki Ninja 650R Rebuild Series (more like a restoration series, but whatever…).
Do you have a motorcycle that’s been sitting for a long time? If so, you should probably drain the gas, rather than run old gas through your tank. But removing a gas tank to drain it can be messy to do yourself, or costly to have a dealer do for you. So there’s a third option: You can siphon that old gas out. It’s an easy way to get old gas out of your gas tank, without having to disconnect fuel lines, lift up heavy gas tanks, or risk making a huge mess or damaging your tank.
As you ladies and gents who regularly check out the site already know, I bought a 2006 Kawasaki Ninja 650R with only 200 miles, for only $1,000. An absolute steal of a deal. The bike had been sitting for over a decade, so I knew I was going to be putting a little work into it. In previous episodes of the Kawasaki Ninja 650R rebuild series, I brought home the bike and got her running, but just because she can run, doesn’t mean she should run. The gas is old, the oil is old. It’s time to get some fresh fluids in there.
What am I up to today?
Today I’m going to be getting the old gas out of the bike, and then putting some fresh gas in. The downside of siphoning out gas rather than actually draining the tank from the bottom, is your risk leaving anything at the bottom of your tank down in there. However, once I determined that the tank had previously been drained, that stopped being a concern. To make life easy, I’m using the following:
1) Fuel transfer pump
2) Empty juice boxes (to drain the gas into)
3) Rags (to clean up any gas spills)
3) Black Widow motorcycle table lift from DiscountRamps
The fuel transfer pump is a breeze to use
Once set up, fuel transfer pump is pretty easy to use: There are a couple adapters for the hoses to keep them in place. Make sure to use the smallest tube in your kit for siphoning fuel out of your motorcycle gas tank.
Within seconds of when I started pumping, the gas just starting flowing out all by itself. In fact, it came out in a huge gush of gas at first that I had to clean up. If you’re trying this at home, have some rags on hand.
When you’re done, I recommend putting all the gas pump thingy bits in a big freezer bag so you’re not going to lose any of the pieces. Next, grab a Jerry can that’s rated to transport gas (you can buy some at most gas stations), fill up your tank, and make sure the bike runs.
I didn’t run the Ninja 650 for too long because I know that the oil in it is still a couple years old. Instead I’ll wait until I do the oil change tomorrow, and then let it idle longer and rev it up. Expect a “how to do an oil change on a Kawasaki Ninja 650R post” to come out soon!
